Sony VGN-FW373J Battery
Your Sony VGN-FW373J battery makes your laptop portable which gives you the opportunity to use it where you want. Not all batteries are the same, be sure to check the model number and compare it to the one you are going to replace. More amps in a battery basically means the longer you will be able to use the laptop on a single charge. Getting a battery with a higher amp rating is OK, as it signifies that the battery can last for a longer period of time on one charge. What is important is the actual size of the battery and the connection it has.
Major clues your battery is dead
- The Sony laptop does not turn on when it is unplugged
- The laptop does not run longer than one hour before it shuts itself down
- The laptop battery gets puffy like its about to burst
