Sony VPCY21DGX Battery
Your Sony VPCY21DGX battery allows you to move freely about so that you can use it wherever you fancy. Because no battery is the same, make sure and double-check the size and model number in order to make sure it is similar 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 really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection. More amps in a battery basically means the longer it will last on a single charge.
