Diferent Batteries of Laptop

There are different types of batteries like HP

, DELL,GATEWAY, APPLE and so on. While here I prefer to give a description of the different materials of batteries, in order to have readers know more about your battery.

Lithium battery

Lithium batteries, on the one hand, are taken as a storage system memory or configuration information backup power; on the other hand is in the handheld computer as the main power supply. It uses lithium as the anode, the synthesis of a special alloy of manganese dioxide as cathode. Lithium battery's shell has three years span life. Higher ampere-hour lithium level can work in a long time to maintain the basic stability of the voltage output.

Nickel-cadmium battery

Nickel-cadmium batteries are for notebook computers and laptop computers in the main source of energy. As the nickel-cadmium battery manufacturing the original basic shape and size from the restrictions, therefore, use it for special battery configuration is especially good.

Nickel-cadmium battery is a rechargeable battery; it uses nickel-hydride as the anode, made of cadmium with a special compound as cathode. Ampere-hour battery is in an advantage of this high rate. Drawback is the lower energy density and must be frequently charged.

Nickel metal hydride battery

Nickel-metal hydride battery is a new concept of rechargeable batteries; design of this battery is intended to provide more than the nickel-cadmium battery energy density. Since 1990, the first time in a small computer to use this battery has up to now; nickel metal hydride battery has been substantial performance improvements, while also lowering the cost of many.

Nickel metal hydride batteries and nickel-cadmium battery manufacturing and the operation principle is very similar. The difference is, nickel metal hydride battery using a metal hydride alloys to replace the nickel-cadmium batteries of cadmium, it uses a proprietary electrolyte, so that it can be sustained in 9A or more discharge current to 0.8Ah to 2.40Ah discharge rate of more than provide 1.2Vdc voltage. The battery energy is of density of more than 80Wh/Kg (38.1Wh/Kg). As the nickel-metal hydride batteries with such outstanding technical indicators, it will have broad application prospects.
