Compaq 511 Battery
Your Compaq 511 battery makes your laptop portable so as to work or play wherever you fancy. Because no battery is the same, make sure and double-check the physical connection and size and compare it to the old one. The more power the battery has, the longer you will be able to use the laptop on a single charge. Buying a battery with a higher milliamp rating is fine, it just means the battery will go further on a single charge. What is important is the physical size of the battery as well as the connection.
Major signs your battery is in dire need of a replacement
- The laptop lasts under ten minutes while unplugged
- The unit is unable to boot up while not connected to the AC adapter
- The laptop battery is puffed up and looking like it is going to burst
