Laptop batteries are made up of one or more cells. Laptop computers are actually small mobile computers that work just like desktop computers. Laptops can be carried anywhere, so they need to be wireless. Batteries help make this possible, so they are essential in a laptop.

Laptops usually run on batteries when a power source is not available nearby. Adapters can also help as the charge laptop batteries. With the improvement and advancement of technology, laptops are becoming very popular.

The introduction of laptop processors has solved this problem. This reduces the total power requirement drastically.

The most recent laptops use lithium ion batteries. Generally the life of a laptop battery is two to five hours, but if the laptop is being used very extensively, the life may get reduced to as little as one hour. The chemicals that are used inside the battery are usually degenerated when the life of the battery drops. It then needs to be replaced. Lithium ion laptop batteries can live long for one to five years. It depends greatly on the extent to which it is used.

If you want to go for a refurbished laptop then you are not making a wrong decision. Just check the battery before you buy it.
