Every laptop battery carries a certain “reservoir,” or capacity of charge per cycle. Much like your car’s gas tank, you fill it up every so often and then use the gas bit by bit. In the case of a laptop battery, the tank usually holds 2,500 to 4000 milliAmp hours.
Just like your car, your laptop computer battery lasts longer depending on how you “drive” your laptop. Many laptop users are familiar with the Power Management settings icon in the Control Panel, which allows the user to control use of the laptop battery. This control forces your laptop to conserve its fuel by limiting the operation of the highest energy-consuming functions. Unfortunately, there is a trade-off between computer performance and energy conservation.
