One friend has this dell CC154 battery, and he has so many questions about the laptop battery. That strikes me to post this article. That is on batteries with different materials.

At present, li -ion battery is the most prevailing one. They are not only with light weight but with long life. There is slight memory effect of Li-ion battery. You can use it tens of thousand times. In addition, it won't get overheated if you over charge it. Moreover, they are thinner comparatively. And that is why it can be popularly adopted in current laptop. for this CC154 battery, it belongs to this type.
Besides the li-ion battery, there are Nickel-cadmium (NiCad) battery and Nickel Metal Hydride (NiMH) battery. They have their own advantages. For the NiCad battery, it is common in notebook computers of the old type. You can see this type of battery in the older laptops. However, because of memory effect, the continued use of the battery will increase the effect gradually. As time goes by, battery plate will produce bubbles. Thereby it reduces the capacity of the battery. The only way to solve this problem is to completely discharge the battery. Thus, this battery has a very conspicuous defect: explosion. That is really terrible. As to Nickel Metal Hydride (NiMH) batteries, it's the trans-product between lithium battery and the Nickel-cadmium battery. Later, it's replaced by the lithium battery. Just as this dell CC154 battery, it's made of lithium.
Many laptops equipped with lithium-ion battery claimed 5 hours battery life. That is not the truth. Hard disk drives, other disk drive and LCD display consumes a lot of battery power. Even through a wireless connection to browse the Internet will consume some battery power. Many notebook computers have installed the power management software to extend battery power is low or to save energy.

As the development of the technology, laptop battery has increased its quality and capacity. and its performance have leveled up. That provides more convenience to the businessman who travels a lot with the laptop. In new future, we can use higher quality batteries.
