Sony PCG-SR31K Battery
Your Sony PCG-SR31K battery allows you to move freely about which gives you the opportunity to use it anywhere you please. Buying a battery with a higher milliamp rating is fine, it simply means it is a stronger battery. What is important is the connection type and physical size of the battery. More amps in a battery basically means the longer you will be able to use the laptop on a single charge. Not all batteries are the same, make sure and double-check the physical connection and size and compare it to the one you are going to replace.
Main clues your battery is going to die
- The battery has its case swollen like its about to burst
- The unit does not turn on while not connected to the AC adapter
- The laptop lasts under 20 minutes while unplugged
