Sony VGN-SZ340W Battery
Your Sony VGN-SZ340W battery allows you to move freely about so that you can use it anywhere you please. More amps in a battery basically means the longer it will last on one charge. Not all batteries are the same, make sure and double-check the physical connection and size and compare it to the old battery. It is OK to buy a battery with more milliamps, it just means the battery will go further on a single charge. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection.
