just myself

Some friends in the cell phone battery to charge, charge that the longer the use of the longer, in fact, this is not right. We look at the most commonly used in the original lithium-ion battery, is generally used (GB/T18287 2000 norms), first of all constant current charge, that is, a certain current, and battery charging voltage as the process of gradually increased, when the laptop battery terminal voltage to achieve 4.2V (or 4.1V), to constant current charge for charge voltage, that is, a certain voltage, current batteries based on the degree of saturation, with the charging process to continue to gradually reduce, when reduced to 0.01C, charging that Termination. (C batteries based on current nominal capacity of a control method that, if the battery is a 1000mAh capacity, 1C charge current is 1000mA, attention mA is not Ah, 0.01C is 10mA.)

Why is that the charge for the end of the 0.01C: This is a national standard GB/T18287-2000 provided as well as the discussions. Previously it was generally for an end to 20mA, the Ministry of Posts and Telecommunications YD/T998-1999 industry standards provided for in the same way, that is, no matter how much powerbook battery capacity, to stop all current 20mA. GB 0.01C provided help to more full charge, through the identification of a party manufacturers benefit. In addition, the national standard provides for the charging time is not more than 8 hours, that is, even if not yet reached 0.01C, 8 hours, and that the end of the charge.
So, no problem with the quality of the batteries should be 8 hours to reach 0.01C, the poor quality of the battery, and then filling it is also meaningless. Lithium-ion or lithium polymer rechargeable batteries in the best rate of 1C, which means a 1000 mAh battery of 1000mA to the current fast charge to charge such a rate can be achieved in the shortest time charge, but will not reduce the Battery performance and shorten the useful life. For the ever-increasing capacity of the battery pack, want to achieve such a satisfaction rate of charge to increase the charge current value is inevitable.

Lithium-ion battery nominal voltage 3.7V (or 3.6V), charging cut-off voltage 4.2V (or 4.1V, the batteries under the brands have different design). What is the difference between battery 4.1V or 4.2V: consumers do not have the distinction, depending on batteries manufacturer of the product specifications. Some brands of batteries are 4.1V and 4.2V common, such as A & TB (Toshiba), the domestic manufacturers is the basic 4.2V. The rechargeable batteries of 4.1V to 4.2V happen: will increase the capacity of the A42-A3, with a good feeling, and standby time, but will reduce battery life. For example, the original 500, reduced to 300. By the same token, to the 4.2V batteries have been sufficient, it will lower its short-lived. Lithium-ion batteries is very delicate. Since the battery within a protective plate, we can rest assured that it had: No, because the board to protect the cut-off parameter is 4.35V (this is good, the bad to 4.4 to 4.5V), protection of the board is to meet in the event, if per Times have been sufficient, the battery will decay quickly.

Therefore, the charge is generally eight hours a disproportionate amount of time is not useful at all.

In the use of lithium batteries should be noted that for a period of time after the battery is placed into hibernation, lower than normal capacity at this time, the time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycle of the battery can be activated, the resumption of normal capacity.
As the laptop battery lithium own characteristics, its decision is almost no memory effect. Therefore, cell phone users in a new lithium battery in the activation process does not require special methods and equipment. Not only is the theory that, from my own practice, from the very beginning, the use of standard methods of charging that “activation” is the best way.
Lithium batteries for the “activation”, a large number of claims: the time to charge more than 12 hours, repeated three times to do in order to activate the battery. “The first three necessary and sufficient to charge more than 12 hours”, it is obvious from the nickel battery (such as nickel-cadmium and nickel metal hydride) inherited. This is why it can be said is the beginning of miscommunication. Lithium batteries and nickel battery charge and discharge characteristics of a very big difference, but also very clear to tell you that I have had access to all the serious official stressed that all technical information and charge-off will discharge lithium batteries, especially lithium liquid Ion battery causing great harm. According to the charge and therefore the best time and method of charging standards, in particular for not more than 12 hours of super-long charge. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of charging.
In addition, the lithium battery in the phone or battery charger will automatically stop after a charge, there is no electricity nickel charger for 10 hours the so-called “trickle” charge. In other words, if your lithium batteries in full, on the white charger is also sufficient. And we can not guarantee that no one latitude battery charge and discharge protection circuit features and never change the quality of safety, so your batteries will be in the long-term hovering on the brink of danger. This is also another charge against the chief reason.
In addition to certain mobile phones, the charge for more than a certain amount of time, if not remove the charger, this time not only to stop charging system, will be the beginning of discharge - charge cycle. This is perhaps the manufacturer has its own purpose, it is clear that on the phone and battery / charger is the life span of a negative. At the same time, long charging would take a long time, often at night, and to our country’s power grid situation, at night in many parts of the relatively high voltage, but also volatile. Said earlier, the lithium battery is very delicate than nickel in the electric charge and discharge aspects of fluctuations in the capacity of resistance is much less, so this brings additional risk.
In addition, can not be ignored other aspects of a lithium battery that is not the same for over-discharge, over-discharge of lithium batteries is also very unfavorable. This leads to the following question.
2, in normal use should start when the charge
In our forums, often see this as the number of charging and discharging is limited, so should the cell phone battery power used up as much as possible and then charge. But I find on a lithium-ion 53977 charge and discharge cycle test table, on the life cycle of figures is as follows:
Life cycle (10% DOD):> 1000 times
Life cycle (100% DOD):> 200 times
DOD is the depth of the discharge of which the initials.
Can be seen from the table, the number of rechargeable and about the depth of discharge, 10% DOD at the time of the life cycle than 100% DOD’s a lot longer. Of course, if the actual charge equivalent to the total capacity of the relative:
10% * 100 = 1000
100% * 200 = 200, which is the complete charge and discharge, or better than some, but in front of friends do say that some of the amendments: Under normal circumstances, you should have a reservation in accordance with the remaining battery power and then run out of charge to the principle Charge, if your battery is expected in the first 2 days you can not
To adhere to the whole day, should start on time charge, of course, if you are willing to carry another charger to the office when Bielun.
And you need to charge in order to cope with the anticipated upcoming busy communications will lead to an important event, even if the 851UY is still
There are a lot more than power, then you just charge ahead of time because you do not have a real loss “1″ sub-charge cycle life, it
Is the “0.x” times, but often this will be a very small x.
The remaining battery power and then run out of charge to the principle does not mean that you go to the extreme. And charging the same length of a widespread,
“As far as possible the cell phone’s battery run out of power, it is best to use automatic shutdown.” This is only a matter of fact on nickel batteries,
The purpose is to avoid occurrence of memory effect, unfortunately, it is also spread of lithium batteries on this. It has been because the cell phone battery had

Later in the boot of charge and there was no response, had to give customer service overhaul. In fact, this is due to the battery as a result of the excessive discharge as a result
Low voltage that does not have the normal charge of the boot and conditions.
3, Li-ion battery for mobile phones boils down to the correct approach, I lithium batteries used in mobile phone charging and discharging of the most important tips are:
1, in accordance with the standards and procedures, charging time, even before the three to do so;
2, When the phone prompts when electricity is too low and should start charging as much as possible in a timely manner;
3, lithium batteries do not need to activate the special method, in a normal cell phone use in lithium batteries would be natural to activate. If you insist on spreading the use of “three times before the 12-hour long activation charge” approach, in fact there will not be the effect.
As a result, all 12 hours long pursuit of the lithium batteries and rechargeable cell phone used in automatic shutdown, are wrong. If you are used to be in accordance with the wrong done, please correct in a timely manner, perhaps not too late.
Of course, cell phones and chargers to protect themselves and control the quality of a good circuit, for the protection of lithium 8M815 or have guaranteed. Therefore, understanding the rules of the charge is the key, in some cases also may make some concessions. For example, you found your cell phone the night before bed charge, you can also start charging before going to bed. The crux of the matter is that you should know what is the right thing to do, and not in accordance with the deliberately wrong to do.

In the use of lithium batteries should be noted that for a period of time after the battery is placed into hibernation, lower than normal capacity at this time, the time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycle of the laptop battery can be activated, the resumption of normal capacity.

Said earlier, the lithium iBook G3 battery is very delicate than nickel in the electric charge and discharge aspects of fluctuations in the capacity of resistance is much less, so this brings additional risk.
In addition, can not be ignored other aspects of a lithium battery that is not the same for over-discharge, over-discharge of lithium batteries is also very unfavorable. This leads to the following question.

3, Li-ion battery for mobile phones boils down to the correct approach, I lithium batteries used in mobile phone charging and discharging of the most important tips are:
1, in accordance with standard procedures and charging time, even before the three to do so;
2, When the phone prompts when electricity is too low and should start charging as much as possible in a timely manner;

As a result, all 12 hours long pursuit of the lithium iBook G3 battery and rechargeable cell phone used in automatic shutdown, are wrong. If you are used to be in accordance with the wrong done, please correct in a timely manner, perhaps not too late.
Of course, cell phones and chargers to protect themselves and control the quality of a good circuit, for the protection of lithium batteries or have guaranteed. Therefore, understanding the rules of the charge is the key, in some cases also may make some concessions. For example, you found your cell phone the night before bed charge, you can also start charging before going to bed. The crux of the matter is that you should know what is the right thing to do, and not in accordance with the deliberately wrong to do.

1, lithium-ion battery nominal voltage 3.7V (3.6V), charging cut-off voltage 4.2V (4.1V, the batteries under the brands have different designs). (Li-ion batteries is the norm: lithium ion secondary battery)

2, to the requirements of lithium-ion rechargeable laptop battery (GB/T18287 2000 norms): First of all, constant current charge, that is, a certain current, and battery charging voltage as the process of gradually increased, when the battery terminal voltage to reach 4.2V (4.1V), Constant change Charge for the charging voltage, that is, a certain voltage, current batteries based on the degree of saturation, with the charging process to continue to gradually reduce, when reduced to 0.01C, that the termination charge. (C batteries based on current nominal capacity of a control method that, if the battery is a 1000mAh capacity, 1C charge current is 1000mA, attention mA is not mAh, 0.01C is 10mA.) Of course, that standard is 0.01 C5A, here I simplified.

3, 0.01C why that was the end of the charge: This is a national standard GB/T18287-2000 provided as well as the discussions. Previously it was generally for an end to 20mA, the Ministry of Posts and Telecommunications YD/T998-1999 industry standards provided for in the same way, that is, no matter how much battery capacity, to stop all current 20mA. GB 0.01C provided help to more full charge, through the identification of a party manufacturers benefit. In addition, the national standard provides for the charging time is not more than 8 hours, that is, even if not yet reached 0.01C, 8 hours, and that the end of the charge. (No problem, the quality of the batteries should be 8 hours to reach 0.01C, the poor quality of the ibm battery, wait and meaningless)

4, What is the difference between battery 4.1V or 4.2V: consumers do not have the distinction, depending on batteries manufacturer of the product specifications. Some brands of batteries are 4.1V and 4.2V common, such as A & TB (Toshiba), the domestic manufacturers is the basic 4.2V, but there are exceptions, such as Tianjin is the power of God 4.1V (but also by a 4.2V).

5, the rechargeable batteries of 4.1V to 4.2V happen: will increase the capacity of the battery, with a good feeling, and standby time, but will reduce battery life. For example, the original 500, reduced to 300. By the same token, to the 4.2V batteries have been sufficient, it will lower its short-lived. Lithium-ion batteries is very delicate.

6, since the battery inside a protective plate, we can rest assured that it had: No, because the board to protect the cut-off parameter is 4.35V (this is good, the bad to 4.4 to 4.5V), protection of the board is to meet in the event, If every time charge-off, the ThinkPad R51 battery will decay quickly.

7, much of the charge current is appropriate: In theory, the smaller of the more beneficial to the battery. But you can not order a battery charge, such as 3 days now. GB provides low-rate charge is 0.2C (standard arbitration charge), but also to the top of the battery capacity of 1000mAh, for example, is 200mA, so we have this battery can be estimated more than 5 hours to full charge. (MAh = current capacity mA × time h)

State technical supervision departments to identify capacity lithium-based high-rate charge of 1C to 0.2C low discharge rate, time to work out the value of capacity, the number of Test 5, 1st capacity to reach the end of the trial. (5 is the chance that if the first pass a test on the back of the 4th does not) allow for testing before the first cycle in advance, in order to 1C is the current charge that 4.2V to cease, and not behind the constant pressure to 0.01 C process, but not 14 hours.

8, Li-ion batteries can withstand much of the charge current: factory tests can be very high, but the elevation ratio requirement for the country 1C, also above the cell, for example, more than 1 hour can be filled. Such a charge current, battery can bear it? For the current lithium-ion batteries, is the only Xiaoyi Si. There are no national standards for the Chargers, enforced by the Ministry of Posts and Telecommunications is the industry standard YD/T998 1999 / 2, which provides for the current charger not to be more than 1C.

9, what is provided for in life: to put it simply refers to the ThinkPad T41 battery at 1C charge N after, 1C discharge, the capacity dropped to 70% at this time of the N is the life. Is not to say that 300 can also be used, the 301 can not be used. GB provides life shall be not less than 300. We usually do not detect the use of the conditions so harsh, life will be longer.

Along with the digital Blasting industry growth, Ni-MH battery for its benefits, environmental protection and the advantages of the players get more and more popular and bulk purchases, from the traditional use of small household electrical appliances: flashlights, clocks, lamps, radios, tape recorders, shaving To be a knife, washing phone, hair dryer, beauty, electric toothbrushes, and other widely used to our new MP3, PDA, WALKMAN, a digital camera, voice recorder, a video game, digital cordless phones and other products to China. A lot of friends through the Ni-MH laptop battery and battery box CRAB brands, with labels for different products for more than a match for the purchase of nickel-metal hydride batteries.
A number of domestic and foreign manufacturers continue to introduce the use of nickel-metal hydride battery of new products we have to speed up the procurement of heat, of course, her unique “quality”, such as energy density, the number of charge, a small memory effect, non-cadmium mercury and other harmful Metal advantage of a series of achievements have a nickel-metal hydride batteries in the market rising.
With everyone in the hands of the nickel-metal hydride batteries in the number of continuous increase in the use and maintenance of science gradually into the line of sight of the concern in the past. As we all know, brand Ni-MH battery life according to the official line is that the charge can be 500 -1000 times, in fact this is a good value, often less than this life. But as long as a reasonable use of the charger, a more in-depth understanding of the Ni-MH battery, we can still do her “longevity.”
1. Under normal circumstances, the new nickel-metal hydride batteries contain only small amounts of electricity, we must first purchase and then charge for use. However, if the battery factory relatively short time, the electricity is enough to recommend the use of first and then charge.
2.’s Purchase of the new nickel-metal hydride batteries generally go through 3-4 times the charge and the use of performance in order to play the best, a lot of friends met for the first time charge of the minor problems, such as charging for the first time after the shooting did not imagine the amount of PP You so much? In the 3-4 times charger and use after all be solved.
3. Although the Ni-MH battery memory effect of the small, we still recommend the use of as much as possible every time after the end charge and is full of one-time, I will not be sufficient for a moment and then charge. However, this “longevity” Oh, that’s important.
4. Rechargeable inspiron battery, charger should pay attention to the surrounding heat, too, what with the fan blowing deliberately not necessary, but bearing in mind that the charger is not to put too much around the debris. Ordinary users in the use of batteries, the batteries are not the exclusive use of storage bag; users to replace the battery after the customary battery placed at random, regardless of whether or not the release of the place clean, damp. The consequences of such a battery is easy to dirty and easy contact with the metal , for example, and other key contacts easily damp, and these are the enemy of batteries. : Users should set up a special cell to place, maintain and clean the battery. In order to avoid problems such as loss of electricity to keep the battery at both ends of the contact point and the internal battery lid clean and, if necessary, use a soft, clean dry cloth graze.
5. Not for a long time, remember that the battery from the battery out of position, under dry conditions recommended card into the battery box, to avoid short-circuit the battery.
6.’s Not a long-term nickel-metal hydride batteries will be stored in a few months later, the battery into the nature of a “dormant” status, significantly reduce battery life. If the nickel-metal hydride batteries have been placed for a long time, I suggest you first slow to carry out sufficient charge is appropriate. Here is another key issue involved: Ni-MH battery, the battery is fully discharged and then save, or save live? These two very different point of view, it should be adopted? Many people believe should be the former, but I think a more reasonable to preserve the battery charged. Because: It has been tested, Ni-MH battery kept charged is the best conditions to preserve about 80 percent. This is because Ni-MH battery self-discharge more (10 percent -15 percent a month or so), if the battery completely discharge and then preserved for a long time not to use, the battery self-discharge phenomenon will cause the battery Over the discharge would damage the battery. Do not believe it? What do you think of buying a new nickel-metal hydride rechargeable batteries is not all there is electricity, which is the reason. : More compared to rectify the wrong point of view, from the start in the right direction maintenance batteries, or else they will backfire.
7. Have made many friends in the post asked how the Ni-MH conduct discharge? The expert asked about the number of batteries, reached the same conclusion to remind friends. Do not try to nickel-metal hydride batteries, rechargeable lead-off put the failure to do so against much larger than their own Ni-MH Inspiron 8200 battery memory effect!
8. Multimeter battery is full of self-test or not. General in charge Ni-MH battery, 1.2V voltage below the normal voltage in full after about 1.4V. We use this to determine, it is easy to judge the status of the battery.
9. Charger can be broadly divided into fast and slow-filling charge. Slow flow of small charge, usually around 200mA, such as our common charge current is 160mA or so. Her charge for a long time and charging the 1800mAh Ni-MH battery to 16 hours or so. Although time is a bit slow, but the charge would be sufficient enough and does not hurt the battery. Fast flow usually charge more than 400mA, charging significantly reduce a lot of time ,3-4 hours you can get, and everyone’s favorite to win. Many types of fast filling, the prices vary. So often we all have doubts, are filling fast, and why the price is a big gap in it? Good charger in particular are filling fast with a good anti-over-charge protection, for example, we the Panasonic common charger Need BQ 390 in this regard was especially outstanding, excellent software, chip design capabilities in the battery charge, Also quick to charge batteries on the injury down to a minimum.
10. There is such a conflict: Slow injury is not sufficient battery charge time is too long, however; fast charge time can be saved, but the batteries have hurt, even if the world is the best surface of the Need for Panasonic BQ390 charger can only be good to reduce the extent of injury , But can not be completely avoided. This contradiction can be resolved is to buy a quick charge and a charge slowly. With sufficient speed and sufficient period of time, for example, at 5, 10, Chong Chongdian slow to switch to one or two. This will also return to the performance of battery-top condition.
11. Batteries are generally used Inspiron 8100 battery, that is, 4 or 6 series, this time to maintain the balance of each cell is very important, otherwise, because of a battery problem affected the entire battery pack. First, the battery capacity to ensure consistent, it is best to choose the same brand of the same type of battery at the same time to buy. Then, to keep the internal battery power, said simply, is that the battery power is either full or empty. If there are more cell group composed of a number of batteries, you can try to “select” look. That is specific to capacity, similar to parameters such as voltage battery series into a single set of batteries, due to inadequate conditions, under normal circumstances, let us test after the end point of voltage and power good voltage washed it.
12. To talk about the final charge and discharge.
The high-grade NI-MH battery charger using a detection-DELTA V battery voltage to determine whether the battery is full. When the battery voltage discharge curve and a little bit similar to the beginning of a more rapid rise, followed by the slow rise until sufficient good, fast start and voltage drop in the rate of decline is not great. Before commonly used nickel-cadmium batteries are also similar, but the decline in the speed and range than the NI-MH are great. The largest number of chargers on the market (that’s less expensive) is often used in value-charge pressure, such as Po-old GP is the 1.4V charge voltage value, that is, into the battery when the 1.4V voltage in the absence of the poor, charging the end of . Such an outcome often is not full of batteries, especially older ones, some of the batteries, due to increasing resistance, the real increase in Inspiron 4000 battery on a lower voltage. This charger current and often smaller, often have to charge more than 10 hours. The use-DELTA V automatic cut off of the charger, because it can accurately control the charging time, it can be more reliable to use the current charge. Current nickel-metal hydride rechargeable batteries for the damage we did not imagine the stakes, the opposite, the use of DC now, more high-current charge. The first is a matter of time, do not have to speak. Then, Ni-MH battery has a characteristic that you charge the greater the current, it can release the greater the current, DC power is a tiger, not a small current, relatively speaking, therefore, the use of relatively large Current charge is a wise choice, can increase battery _ clean. 5, the general charge current should not exceed 1.5C, C for the battery capacity is 1000MAH batteries, not more than 1.5A. I normally charge for use of 0.5C (my current adjustable charger). Discharge, under normal circumstances, DC after the black screen will be able to take charge of, NI-MH little memory effect. But after a period of time, as well as to balance the battery cell activation, to control the discharge of the Inspiron 600m battery voltage termination. NI-MH battery voltage of the termination of 0.9V, the discharge time careful not to over-discharge, on each battery 0.9V when you can stop the discharge. NI-MH battery has not tough nickel-cadmium batteries, the charge had been released and are more sensitive to high temperatures. Charge-discharge temperature. In general, do not let the battery temperature higher than 45 degrees. The battery is full, the batteries will be fever, a high current when the temperature should be about 42 degrees and not more than 45 degrees, otherwise life will quickly reduce the battery internal resistance will increase. In addition, the battery charge after a high temperature, cooling, and so only after their charge, the money would also charge the battery cooling, and so on. Not long after the re-use, the best sufficient to reactivate the battery release several times. The use of normal time to pay attention to maintaining the integrity of packaging paper, there can not be broken in order to avoid a short circuit. Do not tempering the impact of the battery, so do not fire.

What is the use of laptop batteries and maintenance of the taboo? Maintenance of notebook batteries in the end not to be pulled out books, out of power if the how to do? If the laptop battery maintenance of good words to use up to how long? See below, it will know.

Laptop battery life is longer, often dissatisfied with the charge, or even show damage, it must use some attention to the maintenance tips: Whether you use the laptop’s lithium notebook battery or Ni-MH battery, battery power as much as possible to use the basic And then do charge (less than 5% of electricity), which is to avoid the best way to the memory effect. In fact, the lithium-ion battery has some memory effect, Ni-MH battery is more than just a lot smaller. It should be noted that, however, charge, as far as possible to avoid too much time, the general control within 12 hours.

Battery life of notebook batteries, not by the total length of time, but by the charge and discharge to determine the number of times. Here is the notebook maintenance. If the battery will always be loaded to a notebook instead of taking down, even if the machine shut down and remove AC power, the battery would not like to imagine what it has been full of electricity when the state. As the laptop battery in the battery in the integrated control circuit, so even if the computer is shut down when power is power. As the one connected to AC power, will begin charging the battery, when turned on or off the power when your notebook battery will be recharged repeatedly and discharge affect battery life.

To this end, the use of external AC power supply when it is best to unplug the inspiron battery, or notebook battery for a long time in a state of fever have an impact on their life. To maintain the battery, do not have long-term, at least 12 months a red discharge in order to ensure its activity. In the custody of the battery when there is a need to pay attention to. At present, the vast majority of notebooks used in lithium-ion battery for a long time, if not in use, often prone to excessive discharge, may no longer be able to charge batteries for notebooks. In order to prevent the excessive discharge, in a state of semi-charge save in cool dry place, and then once every six months, and then the necessary and sufficient electricity to half of the state.

In addition, the impact on battery life books of factors including the use of the environment temperature (30 ℃ suggested that the use of the following), storage batteries and the battery temperature suffered shock, such as size. Notebook batteries in use for some time would be after the aging (how maintenance is the same), the specific performance of the resistance is bigger in charge when both ends of the voltage rise faster, so that was easy to charge control circuit has been judged to be full of , The natural capacity is lower than before. Notebook battery is a correction to deal with the aging batteries effective way to a small number of notebook batteries have the exclusive use of correction software. If your laptop does not discharge the exclusive use of software, so the battery can be in accordance with the following steps for maintenance:

● screen saver will be banned;
● In the Windows power management will power scheme is set to “always open”;
● alarm at the tab will be “insufficient power warning” is set to 10% of the operation is set to “operate”;
● will be “a serious power shortage alert,” set to 3% of the operation as a “wait”;
● the screen brightness to the maximum;
● confirmed that all the windows closed, and save all the data before work;
● confirmed that the Inspiron 8100 battery charge in more than 80%, pulled out all external power supplies and equipment.

Discharge after the end of the notebook will automatically shut down after the power supply will be planted to allow notebook charge, the process can be repeated 2 to 3 times to enable the continued low current battery discharge, which discharge in the state of our day-to-day use is not possible Achieved, the effect of the discharge and those dedicated basically the same software.

Q: What kind of notebook can provide a longer battery life time?

DELL engineers: only low-value CPU frequency is wrong thinking to choose, because the selected components such as LCD can achieve energy-saving, and CPU can be dynamically adjusted according to application frequencies, it can not value the “Ultra Low Voltage.” In comparison, high-capacity battery configuration of the mainstream Centrino notebooks performed well, if conditions allow, can be equipped with the best recommendations of the second block the use of batteries. Usually use the same battery, the time to go out with the original Inspiron 4000 battery . In fact, to buy a piece of notebook batteries are not expensive, you can find those brands are specifically to help manufacturers who wish to purchase. Those manufacturers because there is no pressure on the brand, so prices less than the general.

1, sometimes their own cell phone charger and the battery is full display, and the actual use of a very short time, there is no battery power, how it is going on?

There are laptop battery memory effect, such as: the aging batteries and nickel-cadmium batteries will lead to more cases. For example, a full glass of water, it is frozen, liquid water would be gradually turned into solid ice. Although the ice is not drink the water. Memory effect is similar to “freeze the liquid water into solid water” so that power can not be used, above, due to the effects of memory or battery state, so that power can not be translated into, so although the phone shows the battery power Full capacity, but only a very short period of time.

2, how to prevent the battery memory effect?

Very simple and takes only a per-use mobile phones when the battery completely finished on the use of the line. This will greatly extend the battery life.

3, when the battery memory effect can try this approach?

① battery with a newspaper to wrap a plastic bag and then put into freezer Overwrapping good for three days (newspaper can absorb excess moisture).

② out after three days at room temperature for two days decentralization.

③ two days after the compaq battery charge, full charge after the mobile phone rolled into the test (estimated to save 80% -90%).

4, non-rechargeable battery of common sense and reason to solve the problem?

(1) and the battery charger connection is not correct, the right to be connected;

(2) Contact the battery charger or not clean, need to clean and dry;

(3) battery has been aging and need replacement batteries.

5, battery power faster than normal, common-sense reasons and solutions?

(1) weak cell phone signal in the negative coverage area so that the power consumption accelerated in the normal coverage area, no problem.

(2) mobile phone antenna in use did not open, so that the power consumption to accelerate the use of cell phone antennas formed out of the habit of saving can be.

(3) a new Business Notebook nc6000 battery or a long-term non-use of batteries used in the first three times before they could cross to the normal standards of performance.

(4) of the old battery, or battery memory effect of battery power will be finished within a very short time consumption, the need to replace batteries at this time.

(5) batteries used in extreme temperature, low temperature or high temperature can greatly affect battery performance, often take charge.

6, battery maintenance of a few common sense?

(1) in order to extend battery life, the charging time can not charge more than the necessary period (5-7 hours); but the first three of the new battery to be used to discharge the phone automatically shut down after the 8-12 hour rechargeable ! In order to ensure that the battery capacity was sufficient to stimulate them;

(2) only when the purchase of the original factory charger;

(3) the EVO N400c battery does not contact with the metal with oil or contact accessories, pay attention to moisture;

(4) batteries should not be dipped into water or thrown into the fire;

(5) Do not put batteries, such as low-temperature refrigerator, such as high temperature next to the stove;

(6) to deal with the battery, use of special facilities;

(7) For the battery exchange, only recognized by the cell phone battery types;

(8) to have the memory effect of batteries, each should end the use of electricity, rechargeable, battery Otherwise, there will be memory effect, greatly reducing battery life.

(9) battery life is normally sufficient to calculate the number of release, and therefore, adequate electricity, run out of electricity, to the maximum extend EVO N410c battery life.

Notebook battery maintenance mode. . . . What is the use of laptop batteries and maintenance of the taboo? Maintenance of notebook batteries in the end not to be pulled out books, out of power if the how to do? If the laptop battery maintenance of good words to use up to how long? See below, it will know. Laptop battery life is longer, often dissatisfied with the charge, or even show damage, it must use some attention to the maintenance tips: Whether you use the laptop’s lithium notebook battery or Ni-MH battery, battery power as much as possible to use the basic And then do charge (less than 5% of electricity), which is to avoid the best way to the memory effect. In fact, the lithium-ion battery has some memory effect, Ni-MH battery is more than just a lot smaller. It should be noted that, however, charge, as far as possible to avoid too much time, the general control within 12 hours.

1. Nickel-cadmium, nickel hydrogen, lithium-ion batteries are three characteristics:
In common: many times can charge and discharge, the number of cycle (life) in more than 500 times.
Different points: nickel-cadmium batteries, nickel is very, very negative cadmium rechargeable batteries. Because there are reasons for cadmium, memory effect; heavier; low capacity; low prices; environmental pollution; to be finished before power can take charge. Ni-MH laptop battery, nickel is very, very negative energy of hydrogen rechargeable batteries without memory effect; more emphasis on lithium-ion battery; a high-capacity nickel cadmium battery; because they do not use cadmium and other harmful elements, and environmental protection; no first use of pre-discharge, but the use of Over time better discharge; moderate prices. Lithium-ion batteries, cathode using lithium compounds, carbon extremely negative 3.6V rechargeable battery. Charging, lithium-ion is in the negative shift between, so-called lithium batteries. No memory effect; lightweight; environmental protection; charge and discharge at any time; of the three highest-capacity batteries; price but more expensive; charger for the more demanding and dedicated charger.
2. The new battery is subject to the general 2 — 3 times charge-discharge process in order to achieve optimum capacity.
3. A new battery or a few months has not used rechargeable batteries that may arise, “full of” show the false impression that the battery can be won, set aside 5 minutes after the charge until normal power showed that when the charge.
4. Lithium-ion rechargeable battery Needless to discharge the former general charger should not lithium-ion rechargeable batteries, rechargeable lithium-ion toshiba battery charger when the use of special.
5. Identification of lithium-ion batteries and nickel-metal hydride battery of visual methods: Ni-MH battery charging there was a slight fever, and lithium-ion rechargeable battery will not heat.
6. Cell phone battery should be full of shine principles for a new battery or the depth of discharge the battery, the initial charge should be taken slowly to reach the maximum capacity before using fast charge.
7. In order for mobile phones consume less battery power, please refer to the use of the following recommendations:
A. The use of mobile phones to make full-day money will be pulled out, so that the signal stability;
B. The network is extremely weak signals, to avoid calls for a long time;
C. Please necessary to set the lowest possible number of mobile phone models (with the exception of power), set the pattern, the more power the greater;
8. Brand cell phone batteries are available in-house over-current protection, short-circuit when the accident when the internal battery will power, not until the short-circuit in order to resume work. Once the counterfeit mobile phone batteries short-circuit, and some even burning fever.
9. From the weight, the weight of the batteries is not necessarily good quality batteries, with the volume of nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion batteries, nickel-cadmium batteries heaviest, the lightest lithium-ion batteries are usually fake The PA3107U-1BRS is rechargeable nickel-cadmium batteries Ni-MH battery, nickel metal hydride rechargeable lithium-ion battery cells.
10. Standby time refers to a cell phone in standby mode under the stand-by time. Manufacturers are given the standby time is based on the phone in standby mode conversion to electricity consumption, and this is just a test data. Standby time is affected by a number of factors, such as: battery capacity, the use of mobile phones, network signal strength and the use of SIM cards, network settings, and other features. Call for the standby power consumption is about 10 times more than when. As a result, the cell phone talk time in a row is about one-tenth of standby time. If the stand-by in the course of the call, dial-up, games operation, standby time as a result of these operations will consume more electricity, while significantly deviated from the targets of standby time.
11. Cell phone quality is good or bad, depends on one of the following major factors:
A. Battery capacity: the capacity of the battery (the effective discharge capacity) indicators of standby time and decided to let pass the length of time. High-capacity, and standby time, talk a long time.
B. The battery performance: the impact of the battery performance of the two main factors: the internal resistance of batteries: batteries have a certain amount of resistance, the resistance will affect the charge and discharge performance, resistance too easily lead to “down” and even customs Machine. The performance of PA3285U-1BRS discharge: refers to the smooth discharge and the average discharge voltage. The smooth discharge of the better energy batteries, the higher the effective utilization. Lithium batteries in general than the Ni-MH battery discharge stable and good.
C. Circuit protection functions: to ensure that the batteries in normal working condition.
D. Battery life cycle: The life cycle refers to the battery charge and discharge repeated use of the number of times, the more the number of cycle, the longer the battery life.
12. The selection of cell phones:
A. Choose well-known after-sales service and a clear commitment to the brand
B. Point of sale options: reputable store or shopping
C. Battery neat appearance, comfortable feel.
D. Battery electrode below the corresponding position marked “+” “-” tag
E. Into the phone battery when the hand is good, up and down with ease
F. Battery charging and discharging a good performance
G. Battery manufacturers on a clear outline of the mark
H. Anti-care logo, and carefully identify
13. To the proper cell phone battery?
A. Charge, nickel-metal hydride batteries and lithium batteries do not need special discharge.
B. Charge, as far as possible in order to slow Chong Chongdian to reduce the fast charge mode.
C. Please use the original or the reputation of a good brand charger, lithium batteries use lithium battery charger dedicated, and follow the instructions that would otherwise damage the battery or even dangerous.
D. After three to five times the PA3191U-1BRS fully charge and discharge cycles, the internal chemicals will be activated all, to achieve the best results. Therefore, the initial charge after the results of the battery is not the best reflection of the quality.
E. Phone battery self-discharge exists, when not in use nickel-metal hydride batteries will be a day of surplus capacity by about 1% of the discharge, lithium batteries per day by 0.2 %—- 0.3% discharge.
F. You used to determine the use of, respectively, to choose their own thick, thin batteries, under normal circumstances, the more thin battery, the capacity of the smaller, thicker battery, the greater capacity.
G. Inexpensive charger, low cost, using only a simple circuit design, there is no insurance agencies, large charge current. On the surface, charging time is very short, the more applicable, in fact hidden danger and damage the battery.
14. Attention to the use of batteries:
A. Replacement batteries, cell phones must be shut down power.
B. Do not put batteries in a fire burning, so as not to cause an explosion.
C. Do not touch electrical conductors are very film PA3166U-1BRS, so as not to cause a short circuit.
D. Do not make the damp cell, and even into the water
E. Do not store the battery is higher than 60 ℃ or lower than -20 ℃ environment
F. Not to use counterfeit charger charging, in order to avoid dissatisfaction Sufficient power or damage to the battery.

Laptop battery life is longer, often dissatisfied with the charge, or even show damage, it must be used when the attention of a number of tips: Whether you use the notebook lithium or Ni-MH electric power, to the extent possible, after the exhaustion of the basic electricity charge (electricity Less than 5%), which is to avoid the best way to the memory effect. In fact, the lithium-ion battery has some memory effect, Ni-MH battery is more than just a lot smaller. It should be noted that, however, charge, as far as possible to avoid too much time, the general control within 12 hours.

Battery life rather than by the total length of time, but by the charge and discharge to determine the number of times. If the battery will always be loaded to a notebook instead of taking down, even if the machine shut down and remove AC power, the battery would not like to imagine what it has been full of electricity when the state. Notebook computer batteries due to the integrated battery in a control circuit, so even if the computer is shut down when power is power. As the one connected to AC power, will begin charging the battery, when turned on or off the power, the battery will discharge and recharge again and again, the impact on battery life.

To this end, the use of external AC power supply when it is best to unplug the battery, or battery for a long time in a state of fever have an impact on their life. If the batteries do not have long-term, at least 12 months a red discharge in order to ensure its activity. In the custody of the toshiba battery when there is a need to pay attention to. At present, the vast majority of notebooks used in lithium-ion battery for a long time, if not in use, often prone to excessive discharge, may no longer be able to charge for. In order to prevent the excessive discharge, in a state of semi-charge save in cool dry place, and then once every six months, and then the necessary and sufficient electricity to half of the state.

In addition, the impact on battery life of factors including the use of the environment temperature (30 ℃ suggested that the use of the following), storage batteries and the battery temperature suffered shock, such as size. Battery used in a period of time will be aging, the specific performance of the resistance is bigger in charge when both ends of the voltage rise faster, thus easily be found for the charge control circuit has been filled, the capacity is a natural decline in the . PA3191U-1BRS is a correction to deal with the aging batteries effective way to a small number of notebook batteries have the exclusive use of correction software. If your laptop does not discharge the exclusive use of software, according to the following steps:

● screen saver will be banned;

● In the Windows power management will power scheme is set to “always open”;

● alarm at the tab will be “insufficient power warning” is set to 10% of the operation is set to “operate”;

● will be “a serious power shortage alert,” set to 3% of the operation as a “wait”;

● the screen brightness to the maximum;

● confirmed that all the windows closed, and save all the data before work;

● confirmed that the battery charge in more than 80%, pulled out all external power supplies and equipment.

Discharge after the end of the notebook will automatically shut down after the power supply will be planted to allow notebook charge, the process can be repeated 2 to 3 times to enable the continued low current PA3166U-1BRS discharge, which discharge in the state of our day-to-day use is not possible Achieved, the effect of the discharge and those dedicated basically the same software.
