Do not on the battery in the computer clean boot the computer. For the first time in the use of laptop computers, battery-activated for Operation

In the process of charging the battery, do not unplug an external power supply.

The use of battery time, as far as possible will be used up before all the electricity charge and a charge of electricity will be full, not half way on the charge or discharge. This will keep your battery at its best.

If you do not use a computer for a long time (more than 2 weeks), please take out the battery.

For the storage battery out, you easily stay away from the conductive material (such as water or metal) so as not to lead to short-circuit the battery can not be used.

Separate battery storage time should not exceed the maximum recommended a month, and to ensure that every month or so on batteries recharged.

A separate storage battery, please ensure that the battery power is greater than 80%.

It is recommended that you put the battery temperature range -10 - 35 degrees Celsius in dried storage environments, avoid sunlight.

Laptop batteries after a long period of use, the battery on your proposal to initialize (detailed reference to the operation of laptop Manual).

Since the lithium-ion battery will pollute the environment damaged, but also a certain degree of risk. Please do not arbitrarily demolished, abandoned. Please contact with local authorities to understand that waste.

“There are people,” was published on November 5, “how to deal with waste laptop battery for electric vehicles”, to reflect Mr. Yang, Foshan City, part of the region from December 1 ban on electric bicycles on the road. There are a lot of home electric vehicle battery of people would like to step down when cycling, I learned that the pollution batteries very concerned the proposed guidelines on the proper disposal of waste batteries for electric vehicles.

Moderator of this column will be fed back to the issue of City Environmental Protection Bureau, Environmental Protection Agency to respond as follows: At present, there is the vast majority of the electric bike is used lead-acid batteries contain toxic heavy metals such as lead, the lead-acid batteries used in a special hazardous waste, Its collection, transport links must be included in the hazardous waste management.

Waste electric vehicle battery of 90% of what can be recycled, in particular the plate, bus, the lead column, dell Inspiron 6000 battery waste of Lead, acid or toxic or corrosive, random dumping, scattered, secondary pollution on the environment. In 2003 the State Environmental Protection Administration, in conjunction with relevant ministries and commissions issued a “waste battery control policies”, pollution prevention and control of lead-acid batteries provide clear guidelines should be spent lead-acid sony vgp-bps5 battery recycling, prohibit the use of other disposal methods. Electric vehicle manufacturers and vendors must take responsibility for recycling of used batteries.

According to the “policy”, lead-acid batteries, such as abandoned rechargeable hp f4809a battery (hereinafter referred to as “spent rechargeable batteries”) should be the manufacturer of rechargeable batteries, rechargeable batteries to use products manufacturer, commissioned the production of other battery manufacturers to use their The trademark owner of the rechargeable NB-4L battery recycling business commitment, “spent rechargeable batteries”. Rechargeable batteries and use of these batteries electrical goods sales in its business should be to set up sales outlets of the separation and recovery of waste hp f4812a battery recycling facilities, and standards relating to the establishment of a clear identity.

Knowledge battery maintenance four: pay attention to other matters

To minimize the use of the number of batteries

The number of dell 2M400 battery charging and discharging a direct bearing on the life of each charge a battery to retire a step forward. If you often several times a day in Plug Power, and notebook computers equipped with a battery, battery on the greater damage. Because each access to external power supply is equivalent to charging a dell 2P700 battery , battery on the nature of the Zheshou. While the above theory of the case, but every time the battery is removed very convenient, plus no batteries, if all of a sudden power-down would lead to data loss. Therefore, we recommend that users do not have to use the notebook battery removed. However, if the customer would very much like to save the battery, the vast majority of the time or the use of power, but also to avoid the risk of power, you can choose to use an external power supply when the dell 312-0279 battery is removed.

After the exhaustion of power charge and avoid charging time is too long

After a long period of storagedell 312-0383 battery , dell 312-0386 battery , dell 312-3250 battery , dell 3149C battery , dell 3H625 battery , dell 3R305 battery , dell 4E368 battery , dell 4E369 battery , dell 4P894 battery , dell 5081P battery , dell 5208U battery , dell 53977 battery , dell 66912 battery , dell 6H410 battery , dell 6T473 battery , and battery discharge has a natural process, natural discharge has been finished, it does not affect the capacity of the battery.

Battery maintenance knowledge of the three: Unplug the external power supply when no battery

admin — Sat, 08 Nov 2008 03:33:47 +0000

We often get such a proposal in an external power adapter, the dell XPS M140 battery should be removed, that the use of power, the battery will charge on top, not only to increase the number of charge and will charge-off caused by the phenomenon, and Damage the battery life.

The fact is that whether the pool removed, the conflict focused on the use of an external power supply when the dell 0X217 battery is charging up the issue. To know that the number of battery charging and discharging a direct bearing on the life of the general set of lithium battery charge and discharge the number of fixed and charge only the number of 400-600, specially to improve the product but also 800 times, once for each charge on the battery Retired to step forward. The first point of view is nothing but fear the use of power, the dell 01X284 battery will charge on top, not only to increase the number of charge and will have sufficient cause.

But the big brand models, full of battery power on the computer, using an external power supply when it will no longer charge. In fact, a lot of notebook manufacturers are taking into account the vulnerability of the dell 0XR693 battery and products to add to the protection of battery technology, and therefore different from the corresponding brand notebook battery charge protection technology is different, as some large companies in this area very It is true that as: IBM, Hewlett-Packard, Toshiba, Compaq and so on. One of the most thoughtful consideration is IBM, IBM laptop battery discharge can detect the situation, ThinkPad notebook battery power only less than 95% of the time will automatically charge. This battery can play a good role in the protection, quite a number of other companies have to follow. Therefore, such as batteries, you do not need to use the time to pull down, because only when less than 95% of electricity when it will charge.

But even then, if you are using the computer for a long time, or the battery will be removed to better notebook for a long time because the heat generated when running on battery to a certain extent of the injury. However, some other “brand” of dell 0XR693 battery , may not enjoy such treatment because it has not done inside the battery protection technology. I like to use a certain brand of notebook computer, a battery on top in the use of an external power supply certainly have to charge about electricity, because the battery when the store will have wear and tear can not be 100%, and as long as it is not 100% , Connected to the power supply on the charge. Every time an external power supply on access to the equivalent of battery time, although only a small charge will be the time. Therefore, we proposed the use of the time according to their own machine case may be, look at notebooks statement, choose to use an external power supply when the dell 1691P battery is removed.

Tips: brand model by adding a battery of battery protection technology, generally do not have to worry about external power supply can cause the dell 1K500 battery to the charge-off, small brands may not be such a treatment, so that everyone in the use of the time based on their own machines The case may be, look at notebooks statement, choose to use an external power supply when the dell 1X793 battery is removed.

The second battery maintenance knowledge: There stresses discharge charge

admin — Sat, 08 Nov 2008 03:26:26 +0000

General rechargeable dell Latitude D800 battery through a chemical reaction to store electronic energy, so it may be because the capacity of the temperature, not the length of time, load and the use of the environment and the number of affected. We usually get such a proposal, the use of dell Latitude D820 battery power should always be used after all, so that notebook computers automatically shut down power to recharge every time must be filled.

However, the actual situation is generally used when the batteries need recharging when the computer prompts another charge, of course, prompts the time set, the default is 3%. Whether the use of laptop power lithium or Ni-MH battery, these batteries have been the memory effect, Ni-MH dell Latitude D810 battery has a memory effect is obvious, but the lithium power will be the same memory effect, but its memory effect than Ni-MH small number of them. Lithium is no power on the memory effect that no more than exaggerated advertising business irresponsible behavior is totally misled. Since then the dell Latitude D830 battery has a memory effect, charging it when it should be noted, as far as possible and then run out of charge, but there is no need to deliberate must say that the computer automatically shut down, so did not use up any harm (as with a notebook battery charge Discharge protection, the general notebook automatic shutdown is less than the standard dell Latitude PPL battery discharge protection), but you do not feel so tired? In fact, less than 3% of the charge in this way on the good, there will certainly be the effect of memory, compared with the natural wear and tear, nothing should be.

Suggest you to the battery every few months to carry out a deep discharge the battery in order to optimize performance. This is accomplished through use of battery-powered, the dell Latitude PPX battery capacity has been used to 0% (this time the system will automatically enter standby or hibernation state, according to the BIOS settings in different). And then connected to the AC charger has been full of up to 100%.

Tips: When the batteries are generally used in the computer prompts the need for re-charging charge, of course, prompts the time set, the default is 3%.

Full charge and discharge the right way is first of all in the Bios in the closure of energy-saving options, and then Windows “power scheme in” all elections are “never” and “alarm” option to remove the hook of all, when Electricity consumption about 5% of the left when to restart the computer, the screen display information based on self-keyboard Pause button to suspend and then shut down the screen to allow low-current dell Precision M65 battery in the case of automatic discharge until the shutdown recharge, a charge that is fully completed.

To extend battery life, in daily use should pay attention to the energy-saving, you can Bios of power options “Maximum dell XPS M1210 battery Life”, in addition to the Bios you do not shut down a number of commonly used equipment such as parallel port, infrared, etc. ; Windows in the “power management” in the dialog box choose your power program; of course, some of the CPU can use the software so that the CPU cooling down to conserving energy.

Terms:

StandBy mode (standby): displays, hard drives, audio has been shut down. By Fn F3 operation.

Suspend mode (hang): All the tasks have been stopped and saved to memory, in addition to the memory of all the equipment outside have been stopped. By Fn F4 operation.

Hibernate mode (dormant): All the tasks have been stopped, and the current state of memory and hard disk to be stored in the system shutdown. By Fn F12 operation.

Battery maintenance knowledge of the cell to activate the new one

admin — Sat, 08 Nov 2008 02:49:51 +0000

When talking about the use of new dell Latitude D500 battery , we often see this kind of perspective: “we buy a new battery, there will be more than 3% of the electricity, the battery’s power than is used up, until the shutdown, and then External power supply charge. Recharge time must be more than 12 hours, repeated three times to do in order to activate the cell. ”

Is this view is correct or not correct? In fact, most of the cases, we do not have been so troublesome to activate a new battery. This is because most of the brands in the factory when the dell Latitude CPID battery , dell Latitude CPIR battery , dell Latitude CPM battery , dell Latitude CPT battery , dell Latitude CPX battery have been completed and the activation of the work of the notebook battery factory with a bit of electricity to avoid natural wear and tear caused damage to the battery. The battery should be activated in the absence of the protection circuit of manner, with its own lithium battery circuit protection circuit, this circuit is designed to avoid over-charging and discharging of the battery, battery in a general, the charging indicator light to turn off time , On the battery charge is not into power, then you plug in the power plug on the face of rechargeable batteries to carry out what is the use?

From the dell Latitude D800 battery will be able to see the situation on the battery charge there, and teach you a simple way to be able to determine there is no battery during charging, the battery will have time to heat, when the battery is full after an hour (power Do not pull the plug), then you try the battery to see if the battery does not heat hot yet? The results must be cold, not because the battery charge and discharge status, of course, not heat.

Notebook makers in the factory when the proposed new dell Latitude D620 battery for more than 10 hours. This may be the words so that some users have had the first wrong, this writer’s view is that notebook makers should be taken into account some new users to use a new battery when not fully grasp the skills of charge, so that they can simply charge 10 hours, so it should be the business expediency.

Tips: In fact, most of the cases, we do not have been so troublesome to activate some new dell Latitude D505 battery , dell Latitude D510 battery , dell Latitude D520 battery , dell Latitude D600 battery , dell Latitude D610 battery .

Proton exchange membrane fuel cell research since the humidifier

admin — Thu, 06 Nov 2008 08:45:19 +0000

Abstract: Analysis of the proton exchange membrane fuel cell in the way of transfer of water and put forward the need for fuel cell humidifier, introduced the study is being applied from the humidifier Technology Research, pointed out that since the humidifier technology is the future of Proton Exchange Membrane Humidifier fuel cell technology development, with good prospects for research of laptop battery .

Proton exchange membrane fuel cell (PEMFC) as a highly efficient, environmentally friendly power generation equipment, research in recent years become a hot spot. At present, the PEMFC for the proton exchange membrane are in need of water can exist proton conduction, and the only fully hydrated state with only the best proton conductivity,Dell battery the proton exchange membrane must contain sufficient water, In a good state of hydration. On the other hand, the battery is too high in water content would lead to the electrode catalyst in the flooded stains, the loss of reactivity; at the same time will lead to its associated gas diffusion layer of water channels have been blocked to prevent the reaction of the gas into the Gas or contact with the catalyst so that the density of air decreases, the sharp decline in sony vgp-bps5 battery performance, the battery in water management has become very important, is a humidifier to solve the battery problems of water management one of the effective ways.

1 PEMFC the need for humidifying

PEMFC anode electrode reaction: H2 → 2H + +2 e -

Cathode electrode reaction: 1/2O2 +2 H + +2 e-→ H2O

Water in the electrode in the process of migration mainly in two ways
⑴ electromigration: H + arising from the anode through the proton exchange membrane to the cathode migrate, it will bring some of the hydration water molecules to form protons (H3O +), electromigration of water, batteries and current density of the proton and relevant number of hydration IBM battery .

⑵ concentration anti-proliferation:HP battery cathode generated electrochemistry occurred in the water, as well as the role of electromigration will cause the cathode side of the water content increased in the anode and cathode between the water concentration gradient. In the role of the concentration gradient, the water from the cathode to the anode will be counter-proliferation, counter-proliferation and migration of water, the water concentration gradient in the water and proton exchange membrane in direct proportion to the diffusion coefficient.

In actual operation, on the one hand, as the current density increases, more and reverse the spread of water are lower than the electro-osmotic migration of water, which means that when the Asus a42-a3 battery cathode Zone has also maintained a fairly good water conditions , The battery anode because of the relocation of the water has reached a dry, high current density, which is particularly obvious. On the other hand, when a larger flow of gas into the battery, air intake in particular the Department cathode intake of proton exchange membrane was dry, resulting in increased resistance of the cell, PEMFC sharp decline in performance, it is essential that the battery into the response Humidifier gases.

At present, people entering the Compaq battery pack response to the air humidifier for dealing with the general use of outside and inside the humidifier humidifier way way way to be both humidifier to use humidifier systems, proton exchange membrane of the water directly from the battery into the The gas to control the reaction. Self-humidifying technology as a new technology, the ability to remove a large, complex support system humidifier to become the focus of attention.

2 Self-humidifying Technology Research

2.1 Since the composite membrane humidifier

PEMFC in the operation, due to the spread of the phenomenon of cross-existence of a small amount of hydrogen will penetrate through the proton exchange membrane electrode to produce oxygen mixed potential, resulting in decreased efficiency and at the same time there are potential safety problems. If so that the response to the proliferation of gas in the synthesis of water-electrolyte membrane, not only to eliminate the adverse effects of the above can also achieve real-time membrane humidifier. Since the new type of composite membrane humidifier of the above-mentioned study is based on the idea Apple laptop battery .

Self-humidifying fuel cell battery operation is to use water to generate its own response to the realization of the membrane humidifier. Since the adoption of humidifier technology, lower production costs, streamline the operation of the battery system to increase fuel cell power than the volume and quality of power than the current people’s self-humidifying the study focused on 3 aspects.

(1) Self-Pt-doped composite membrane humidifier design some scholars consider the adoption of Pt-doped to change the traditional method of solid electrolyte membrane of the micro-structure, makes proton exchange membrane into the air in response to the Pt catalyst for the next generation of water reaction to wetting Membrane.

Watannabe [7] and others try to spread in thin electrolyte membrane Pt nano-particles into the spread of the electrolyte membrane oxidant and reductant Pt particles in the gas-electric Department synthetic water, so that the membrane to maintain adequate hydration status. However, Pt particles in the film scattered unevenly in the network will be formed electronic channel, could lead to the sony pcga-bp2v battery self-discharge occurred because the battery is failure.

Tae-Hyun Yang [8] to consider the two-electrolyte membrane between the introduction of a vacuum sputtering Pt particles layer, penetration into the membrane in response to Pt gas through the catalytic reaction to generate water, wetting the film completed. This approach by a system of the Pt film is more evenly distributed, but the thick membrane (200μm), it will increase the battery internal resistance, gas permeability amount too little, too little water to generate membrane, almost lost since the humidifier The significance of

Fu-qiang Liu [9] In the study, based on Yang’s use of the porous PTFE membrane to Pt particles dispersed, so that the dispersion of Pt layer near the side of the anode, which is conducive to the anode of the humidifier at the same time making Pt content and easy-to-thickness control Self-humidifying membrane changes in the scope of the power applied to smaller sony PCGA-BP2R battery ; However, the production of this film a long time, the relatively high cost, relatively large proton resistance, there are still difficult to avoid the issue of electronic short-circuit, which limits the use of fact Of.

(2) doping substances in water from the composite membrane humidifier design

In the electrolyte membrane in a number of doping absorbent material, the absorbent material can absorb water to form the battery electrolyte membrane wetting.

Watanabe oxide absorbent to SiO2, TiO2, or their mixture of doping in the proton exchange membrane, and through N2H4 restore [Pt (NH3)] Cl2 in the film deposited in Pt particles (1 ~ 2 nm). Experiments show that the sony PCGA-BP71 battery in the low current density of these oxides will work in water, and high current density when the release of water so that it can regulate membrane of the water balance.

L. Wang [10] and others Pt/SiO2 catalyst particles will be evenly distributed among the Nafion resin, the solution adopted by the method of casting a system Pt-SiO2/Nafion/PTFE enhanced composite film, Pt/SiO2 particles on the membrane into the electrolyte and H2 O2 has played a catalytic role in the response generated by water can be absorbed SiO2 particles, which played wettability on the role of the electrolyte membrane.

Rong Zeng [11] and others will PFSI solution and silica mixed, after the cast method obtained PFSI / Silica Composite membrane, researchers found that the silica gel in the film is distributed more evenly in the compound of the proton conductive membrane was a very The large increase in the absence of external humidification, single-cell test performance is better.

2.2 Self-humidifying membrane electrode design

Self-humidifying membrane electrode assembly (MEA) through the gas diffusion layer, the catalyst for proton exchange membrane, as well as to optimize their combined or modified to enhance product of the electrochemical water to the anode of the anti-proliferation, to achieve self-humidifying.

Mao Qiang, Yang Tao made an asymmetric membrane electrode structure is based on the idea that they were on the oxygen electrode and hydrogen electrode for hydrophobic and hydrophilic treatment, strengthening the cathode to the anode water reverse the spread of the net from the cathode to the anode transfer The water can hydrogen electrode in a humid, so the film can maintain water balance.

In the electrode structure on the basis of the above, Wang Cheng, such as sol - gel Nano SiO2 gel, the anode catalyst layer scattered in the membrane, such SiO2 particles / Nafion thin layer of polymer to further enhance the cathode to the anode of the water Anti-proliferation effect.

Some scholars consider the gas diffusion layer (GDL) for the matrix, with the GDL in catalytic coating layer by layer between the carbon and PTFE prepared by the porous layer (MPL) to solve the battery problems of water management. JinhuaChen [15] in the gas diffusion layer and the catalyst layer between the design of a new type of water management (WML), he will PTFE powder and the nano-carbon hybrid spread-the spread of the matrix, from import to export sony pcga-bp2ny battery WML composition of the gradient distribution in Figure 2 (a) as shown.

PEMFC tradition in the relative humidity is increasing, and therefore easily lead to the air intake in the vicinity of the proton exchange membrane was drying, this WML of the PEMFC, from the intake Koudao exports relative humidity in the range of between 80-100% fluctuations, Therefore, proton exchange membrane can maintain good hydration status and better proton conductivity in order to avoid the drying up of the membrane and cathode water, and gas in response to low relative humidity, can increase the hp f4809a battery performance.

2.3 Self-humidifying the structural design of flow field

Since the humidifier is a flow of the main flow to rely on the special board designed to maintain or transfer part of the product of the electrochemical water, batteries for the membrane electrode to create a relatively moist environment, to guarantee its good proton channel.

hp f4812a battery at the entrance of the gas is very dry, the flow of gas through the process, water generated by the battery wetting, in the exit of a certain humidity. F. N. The use Fuchi such as the characteristics of the current use of the air means the battery from the humidifier function.

Wood and others devised a “cross-finger-like flow” of the flow field structure in Figure (3) as shown. The flow chart as a maze of export of gas by forced convection mechanism to reach the catalyst layer cell involved in the response. In the role of shear stress, the flow of water as part of the air out of batteries, reducing the possibility of flooding electrode; the other part is the infiltration of water into dry film membrane wetting.

Some researchers and bipolar plate materials on the surface have been studied. Shelekhinr made in the bipolar plate flow along both sides of the laying of water, the water by the hydrophilic inert materials, such as filter paper, glass fibers, and other components; work when the battery cathode side of the water be absorbed evenly and storage of surplus water , The battery when the water hydrophilic be stored in the water supply membrane electrode in order to achieve self-humidifying membrane. S. H. Ge will be 2-absorbent polyvinyl alcohol sponges were placed on the cathode side of the flow of the upper and the lower part, to absorb the electrochemical reaction to generate the water to wet the dry air entrance.

3 outlook

The PEMFC humidifier in recent years has become an issue of research hot spots. Since the humidifier can be removed due to the technology of its huge, complex external support system aimed at simplifying the system battery, hp dm842a battery to reduce manufacturing costs, since the humidifier research more practical significance, is considered the most promising fuel-cell applications.

Since the humidifier in a comprehensive research results, I believe that since the humidifier in the current research is focused on the design of composite membrane humidifier, if the humidifier from the composite film, since the humidifier membrane electrode, since the flow humidifier The design of the three

MSI Wind NB 9 Cell Battery really emerged

admin — Thu, 06 Nov 2008 08:24:27 +0000

Some people see before the Wind NB 9 Cell laptop battery , although at that time with Annti official said no such plan, but has been able to buy on eBay in Britain, asking for a group of 115 U.S. dollars, equivalent to about RMB 786 yuan. Wind NB mounted, looks a bit small really fat, but the MSI Wind NB forum in which to get some people have a dell battery , the actual testing of up to 7.34 hours, and good-looking than the DIY version of the more.

PS. It is said that this is very much like Sony battery manufactured by Medion, as Medion has launched looked like the Wind NB light of the provincial electric pen, pulling even ~ ~ MSI is not officially out, and so on and after that they can ask Xiaobian Known.
