1: notebook computers do not need to buy back three times repeated charge-discharge
Unless you buy a notebook computer inventory is more than a year of the product, otherwise we will not need it, because the batteries in the laptop battery when the factory had already been started, and batteries in laptop batteries packaged as time […]

And the type of battery charger does not match: If buying a lithium laptop battery, using a nickel-metal hydride rechargeable battery charger, or lithium battery chargers for nickel-hydrogen batteries. Lithium-ion batteries and nickel-metal hydride rechargeable batteries do not require the same way, (the rechargeable lithium batteries for the way: first constant current charging to protect […]

1, how the new batteries
     In the use of lithium batteries should be noted that some time after the battery is placed into the dormant state, at less than normal capacity, thus shortening the time. However, lithium batteries can easily activated, as long as three to five times the normal charge-discharge cycle can be activated […]

   This summer, music from the streets and alleys in a group of young people are active volunteers. A total of 200 of these volunteers, they are a number of groups at various locations for “replacement” activities: the recovery of batteries at the same time, presented to the public the latest influx of “green handbag.” […]

Development of battery life
In a remote control model of history, nickel-cadmium batteries (Nica) is the oldest battery energy, change in the use of materials for nickel-hydrogen batteries (Nimh), the battery and use the energy of a very substantial increase, both Of the laptop battery has a great stability, both in the high current charge, the […]

With notebook prices continue diving and improvement of living standards, more and more people use a notebook, and some people even use notebook has gradually replaced the desktop. However, the notebooks are all the various components of life, which is the most Jiaoqi inside, I am afraid that the LCD screen. To know that a […]

     The battery itself complex electrochemical reaction leading to its transient voltage response. Figure 1 a show that the lithium-ion batteries from the beginning of the electrode charge transfer basic steps (with the other steps similar to the laptop battery). 
       Charge must first of all through the electronic storage of energy in the form of […]

1, lithium-ion laptop battery nominal voltage 3.7 V (3.6V), charging cut-off voltage 4.2 V (4.1V, batteries under the brands have different design). (Li-ion batteries standard argument is: lithium-ion battery)
»» 2, the demand for lithium-ion batteries (GB/T18287 2000 norms): First of all constant current charging that certain current and rechargeable battery voltage with the process of […]
