Sony VGN-SR499DCB Battery
Your Sony VGN-SR499DCB battery allows you to move freely about which gives you the opportunity to use it wherever you fancy. More amps in a battery basically means the longer it will last on one charge. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old battery. It is OK to buy a battery with more milliamps, as it just means the battery will last longer. What is truly important is the physical size of the battery as well as the connection.
General indicators that your the li-ion battery is in need of replacing
- The laptop lasts way less than it used to before it shuts itself down
- The battery has its case swollen and looks like it will explode
- The unit will not turn on when it is unplugged
