Sony PCG-931A Battery
Your Sony PCG-931A battery makes your laptop portable which gives you the opportunity to use it inside, outside or anywhere your heart desires. The more power the battery has, the longer you will be able to use the laptop on a single charge. Because no battery is the same, make sure and double-check the physical connection and size and compare it to the old battery. Buying a battery with a higher milliamp rating is fine, because it simply implies that the battery will last longer. What is truly important is the physical size of the battery as well as the connection.
Signals your battery will not live much longer
- The laptop lasts less than half an hour before it shuts itself down
- The battery gets puffy and looking like it is going to burst
- The laptop is unable to boot up when not connected to the charger
