Sony VGN-BX645P Battery
Your Sony VGN-BX645P battery allows you to move freely about so as to work or play anywhere you please. Not all batteries are the same, be sure to check the part number of the new battery and compare it to the old one. 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 really is critical to a battery fitting your laptop is the connection type and physical size of the battery. The more power the battery has, the longer it will last when fully charged.
