Sony VGN-FW490J Battery
Your Sony VGN-FW490J battery makes your laptop portable so that you can use it anywhere in the house or even outdoors! Getting a battery with a higher amp rating is OK, as it just means the battery will last longer. What is truly important is the physical size of the battery as well as the connection. Not all batteries are the same, make sure and double-check the model number and compare it to the old battery. The more power the battery has, the longer it will last on one charge.
