Toshiba Satellite L640 Battery
Your Toshiba Satellite L640 battery makes your laptop portable so as to work or play anywhere you please. Not all batteries are the same, be sure to check the physical connection and size and compare it to the old battery. The more power the battery has, the longer you will be able to use the laptop on one charge. Buying a battery with a higher milliamp rating is fine, as it signifies that the battery can last for a longer period of time on one charge. What is truly important is the connection type and physical size of the battery.
