Sony VPCSA490X Battery
Your Sony VPCSA490X battery makes your laptop portable so as to work or play wherever you fancy. 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. More amps in a battery basically means the longer it will last on one charge. Not all batteries are the same, be sure to check the physical connection and size and compare it to the old one.
