Sony VGN-AR690U Battery
Your Sony VGN-AR690U battery allows you to move freely about so that you can use it inside, outside or anywhere your heart desires. Not all batteries are the same, make sure and double-check the model number and compare it to the one you are going to replace. More amps in a battery basically means the longer it will last on a single charge. Getting a battery with a higher amp rating is OK, because it simply implies that the battery will last longer. What is important is the actual size of the battery and the connection it has.
Subtle cues of an inadequate li-ion battery
- The laptop lasts less than an hour before it dies
- The Sony laptop does not turn on while unplugged
- The battery is puffed up like its about to burst
