Sony VGN-FJ290 Battery
Your Sony VGN-FJ290 battery allows you to move freely about so as to work or play wherever you fancy. It is OK to buy a battery with more milliamps, 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. More amps in a battery basically means the longer you will be able to use the laptop on a single charge. Not all batteries are the same, make sure and double-check the model number and compare it to the old one.
Main clues the primary battery is in need of replacing
- The battery is puffed up like its about to burst
- The Sony laptop will not turn on when not connected to the charger
- The laptop lasts under 20 minutes before it dies
