Sony VGN-FW488J Battery
Your Sony VGN-FW488J battery makes your laptop portable so as to work or play wherever you fancy. Not all batteries are the same, make sure and double-check the model number and compare it to the old one. It is OK to buy a battery with more milliamps, as it just means the battery will last longer. What really is critical to a battery fitting your laptop is the connection type and physical size of the battery. The larger the battery, the longer it will last when fully charged.
Some warnings the li-ion battery is on its last leg
- The laptop lasts way less than it used to before it shuts itself down
- The battery has its case swollen like its about to burst
- The laptop refuses to turn on when it is not plugged in
