Sony VGN-SR140N Battery
Your Sony VGN-SR140N battery makes your laptop portable so that you can use it wherever you fancy. It is OK to buy a battery with more milliamps, it just means the battery will go further on a single charge. What is important is the connection type and physical size of the battery. The more power the battery has, the longer it will last on a single charge. Not all batteries are the same, be sure to check the size and model number in order to make sure it is similar to the old battery.
Warnings of an unhealthy battery
- The laptop lasts under ten minutes before it dies
- The laptop will not turn on when not connected to the charger
- The battery gets puffy like its about to burst
