Laptop batteries are very particular about the way that they are treated. If you treat them well, you should have no trouble getting a long life from them. However, if you don't charge your battery correctly or if you don't know how to take care of it, it will die long before its time and force you to pay a lot of money to replace it. In order to charge your
laptop battery right, you have to start from the first time that you purchase your computer and turn it on. Anyone who buys a laptop should know to turn the computer on and let the battery die completely before charging.
Letting the computer drain itself until the machine actually shuts off will drain the battery completely and get rid of any residual charge so that you can get a fuller charge in the first place. The reason that this is important is
because of how batteries work. A battery charges itself and maintains a charge based on what it remembers. If you charge your battery from half-full all the time, it will only remember how to be half-full. Therefore, the battery life will wear down faster than if you get a full charge every time. Once you have an initial full charge, you can begin using your machine.
