Sony VGN-FW290J Battery
Your Sony VGN-FW290J battery allows you to move freely about so that you can use it where you want. More amps in a battery basically means the longer it will last when fully charged. Not all batteries are the same, be sure to check the model number and compare it to the old battery. Getting a battery with a higher amp rating is OK, as it suggests the battery will last a bit longer on one charge. What is important is the connection type and physical size of the battery.
Main clues the li-ion battery is not going to last much longer
- The laptop lasts less than an hour while using the battery only
- The battery gets puffy like its about to burst
- The unit does not turn on at all when unplugged
