Sony VGN-A690 Battery
Your Sony VGN-A690 battery makes your laptop portable so as to work or play anywhere you please. The more power the battery has, the longer it will last on a single charge. Not all batteries are the same, make sure and double-check the part number of the new battery and compare it to the one you are going to replace. It is OK to buy a battery with more milliamps, 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.
Major clues the primary battery is in dire need of a replacement
- The laptop battery gets puffy like its about to burst
- The laptop does not turn on at all when unplugged
- The laptop lasts less than an hour before it shuts itself down
