Laptops usually consume more power and the batteries should be lightweight and small to fit easily into the laptop. With a typical battery, your laptop can run for about ninety minutes. This will not be sufficient, as you may have to use your laptop frequently while on the move. You can use large and heavier batteries to solve this problem.

Laptop batteries are designed specific to the make and model of the laptop. Thus you require the appropriate battery for your laptop. Depending on the type of battery, the life of the battery will vary. However there are some common features that differ from the normal batteries used for household purposes: Laptop batteries can be recharged. They have many internal cells and there is a small PCB within each laptop battery. The location and shape of terminals vary across different models; Similar to all batteries, electrochemical reaction is created which forces a stream of electrons that traverse from one position to another in the laptop batteries and there are negative and positive terminals which send and receive electrons. However, rechargeable batteries are more complex than normal batteries as the power that is produced by the electrochemical reaction must be reversible. Therefore you should take care when recharging, for ensuring that they perform better.
