Sony VGN-AR720E Battery
Your Sony VGN-AR720E battery allows you to move freely about so that you can use it wherever you fancy. Not all batteries are the same, be sure to check the model number and compare it to the old battery. The more power the battery has, the longer you will be able to use the laptop when fully charged. It is OK to buy a battery with more milliamps, as it suggests the battery will last a bit longer on one charge. What is important is the actual size of the battery and the connection it has.
Major clues the li-ion battery needs replacing ASAP
- The unit does not turn on while unplugged
- The battery is puffed up like its about to burst
- The laptop does not last longer than 45 minutes before it shuts itself down
