Laptop battery is its flexibility and stability of the fundamental, mainstream notebook standard rechargeable battery system. Rechargeable battery system includes rechargeable batteries and power management systems. The laptop battery is also embodied an important part of portability.

Batteries used in notebook computers are three main points: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Nickel Cadmium Ni-Cd, Ni-MH Ni-MH, lithium Li.

Is the first laptop to use Ni-Cd nickel-cadmium batteries, as battery technology was not advanced enough, so a lot of nickel-cadmium batteries with the shortcomings of headache, such as: bulky, heavy weight, small capacity, short life, memory effects, etc.. So basically the current nickel-cadmium batteries have been eliminated, the following detailed description is not it.

Then began to use nickel-metal hydride notebook (NlMH) battery that has a good cost performance and higher power, while "nickel-hydrogen battery is one of the most environmentally friendly battery, pay attention to environmental protection are strongly promoting the use of state nickel-metal hydride battery, as it is easy recycling, and have the least damage to the environment. But NiMH batteries with lithium Xiangbi, or have some disadvantages. charging time is long, the weight of heavy, Rong Liang also smaller than the Li Dian, the battery lasts discharge time Taiduan, there is memory effect, its memory even without the nickel-cadmium batteries so much, but still need to discharge, the user must be exhausted after the charge.

Ni-MH battery lithium ion quickly (Li-ion) battery replacement. Lithium will have a long time ago and began its use is not safe, there is often in charge when burning, burst, and this may be because the lithium element too active reason. Then there is the improved lithium-ion batteries such as Apple A1175 Battery, Apple A1185 Battery, Apple M9324 Battery, Apple M8403 Battery, Apple M7318 Battery, apple PowerBook G3 Battery, Apple PowerBook G4 Battery, Apple PowerBook G4 15 inch Battery, Apple A1012 Battery, lithium element added to inhibit the active ingredients, so that lithium truly achieve a safe, efficient, convenient, and also followed the old lithium eliminated. Distinction between them is simple, the label from the battery can be identified lithium as Li, lithium-ion battery Li-ion. Now, the notebook uses the so-called lithium, in fact, lithium-ion battery. Lithium-ion battery energy storage density, charge, and continued to discharge at any time a long time, usually about 3 hours. The size of the battery capacity from the marked mAh (milliamp hours) to determine the value, such as the 3000mAh, 4000mAh and so on greater value, the greater the capacity of the battery.

Of course there are defects in lithium-ion batteries, such as charge and discharge times of high prices and little more. Lithium battery charging and discharging of the number of only 400-600 times, specially modified products, but many times 800. Charge a per day basis, the best lithium batteries, but also more than two years. The NiMH rechargeable battery can reach 700 times more than some quality products to charge and discharge up to 1,200 times, such a comparison, Ni-MH battery live longer than lithium batteries, and NiMH batteries than the lithium battery prices much lower. Hence, there is no perfect laptop battery.

Most common brands of laptop batteries for the square. The market also has a small number of ultra-thin notebook using cylindrical batteries, such as SONY 505 series, Toshiba PROTEGE series. Battery weight varies according to materials and models, such as volume and shape of the same nickel metal hydride and lithium, but a difference of a lot of weight.

The size of the capacity marked mAh from the battery to determine its Chinese name is mAh. MA-hour size is directly related to the use of laptop time, but can not be generalized. Battery life notebook configurations with a great relationship, for example to speak, HP 6100 notebook with a PIII-M, MOBILITY RADEON graphics cards and many other energy saving technology hardware, with the 4000mAh battery, use the time up to 4 hours. Toshiba desktop CPU with 1800, although with a 4500mAh battery, use the time to 3 hours only. To meet the needs of the general going out to work. This also shows that the notebook is not only mAh battery related hardware, energy-saving technologies is very important.
