Sony VGN-FW140E Battery
Your Sony VGN-FW140E battery allows you to move freely about so that you can use it where you want. The larger the battery, the longer it will last when fully charged. Not all batteries are the same, make sure and double-check the model number and compare it to the old battery. Buying a battery with a higher milliamp rating is fine, as it just means the battery will last longer. What really is critical to a battery fitting your laptop is the actual size of the battery and the connection it has.
Clues to watch for to know your battery needs replacing
- The unit does not turn on when it is unplugged
- The laptop battery gets puffy like its about to burst
- The laptop lasts way less than it used to while using the battery only
