Notebook batteries

The use of rechargeable laptop battery is the relative advantage of one of the desktop, it can greatly facilitate the environment in a variety of laptop use. Introduced the first battery is a nickel-cadmium battery (NiCd), but the Hp F2024B batteries have a "memory effect", each charge to be discharged, very easy to use, and soon they were nickel-metal hydride battery (NiMH) replaced, NiMH not "memory effect", and the weight per unit to 10 percent more electricity. At present, the most commonly used battery is lithium-ion battery (Li-Ion), it has no "memory effect" compared with NiMH, receive more weight per unit of electricity, the price twice as high than the NiMH. In the same weight, the use of the three longer than the battery is 1:1.2:1.9. There is also a battery called polymers, very high capacity, small size, the majority used in Apple Computer.
At present, the use of notebook computer batteries in three main categories: 1. Ni-Cr battery, 2. Ni-MH battery, 3. Lithium batteries; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, lithium LI.
Purchase or replace the laptop battery when, for many users, the "Hp F4812A batteries" may be unfamiliar. First statement, batteries and battery are the two concepts. A battery is a number slightly larger than the thumb, cylindrical, about 7-8 cm, voltage of 3.6v small units, it is called professional called 18650, Sanyo and Samsung is the largest producer. Batteries , like a small battery, the combination of tandem, that is, we can see the battery. Then talk about how to judge the battery is the core of a few:
One way: unplug the battery number of contacts to see him, there are several that several of the core. But this is the "Minister" approach. We take a look at "Cao Chong" is how, "said the elephant" of: take a look at the number of your battery v nominal, such as 14.4v, and then divided by 3.6 to be 4, it proved to be in series with the battery 4. And then take a look at the capacity of the battery block, for example, 4400mAh, then proved to be the two groups mentioned above batteries in series, because the small battery capacity of 2000-2200mAh, or even more, and together the two groups can be reached 4400mAh. According to the two judgments, then the battery is 4 × 2 = 8 cores.
Composition notebook battery
Notebook batteries by the case, circuit board components and Sony VGP-BPS3batteries are lithium-ion battery. It is generally talking about batteries means the Sony Vgp-bps2 battery is the number of batteries, mAh refers to the capacity of notebook batteries.
The main circuit board by the protection circuit (or the second protection circuit), as well as the capacity of the two parts of the circuit composed of the instructions on the laptop battery charge and discharge management and safety.
Notebook battery standby time of major decisions by the mAh value. Under normal circumstances, a few more batteries, mAh value the greater the longer standby time. Notebook battery life mainly by the number of charge-discharge measurement, the quality of the products are generally qualified for 500-600 times. Therefore, the effective use of laptop batteries for 2 years, will expire aging batteries, standby time the impact of the drastic drop in the mobility of notebook computers.
