Sony VGN-AR770 Battery
Your Sony VGN-AR770 battery allows you to move freely about so as to work or play inside, outside or anywhere your heart desires. The more power the battery has, the longer you will be able to use the laptop on one charge. Getting a battery with a higher amp rating is OK, it just means the battery will go further on a single charge. What is truly important is the physical size of the battery as well as the connection. Because no battery is the same, be sure to check the model number and compare it to the one you are going to replace.
Simple signals the li-ion battery has very little life left
- The laptop does not turn on when not connected to the charger
- The laptop does not run longer than one hour while unplugged
- The laptop battery is puffed up and looks like it will explode
