Sony VGN-C291 Battery
Your Sony VGN-C291 battery allows you to move freely about so that you can use it anywhere in the house or even outdoors! Not all batteries are the same, make sure and double-check the size and model number in order to make sure it is similar to the old battery. Buying a battery with a higher milliamp rating is fine, it simply means it is a stronger battery. What is important is the connection type and physical size of the battery. More amps in a battery basically means the longer it will last on a single charge.
