Sony VGN-BX540W Battery
Your Sony VGN-BX540W battery allows you to move freely about so that you can use it inside, outside or anywhere your heart desires. It is OK to buy a battery with more milliamps, as it signifies that the battery can last for a longer period of time on one charge. What is important is the physical size of the battery as well as the connection. Not all batteries are the same, be sure to check the physical connection and size and compare it to the one you are going to replace. More amps in a battery basically means the longer it will last on a single charge.
