Sony PCG-9312 Battery
Your Sony PCG-9312 battery makes your laptop portable so as to work or play where you want. Buying a battery with a higher milliamp rating is fine, because it simply implies that the battery will last longer. What is important is the actual size of the battery and the connection it has. Because no battery is the same, be sure to check the physical connection and size and compare it to the one you are going to replace. The larger the battery, the longer you will be able to use the laptop on one charge.
Major signs of an inadequate battery
- The Sony laptop will not boot up while not connected to the AC adapter
- The laptop lasts less than an hour before it shuts itself down
- The battery has its case swollen and looking like it is going to burst
