Sony PCG-GR390 Battery
Your Sony PCG-GR390 battery allows you to move freely about which gives you the opportunity to use it where you want. Buying a battery with a higher milliamp rating is fine, as it just means the battery will last longer. What is truly important is the actual size of the battery and the connection it has. The larger the battery, the longer you will be able to use the laptop on one charge. Not all batteries are the same, make sure and double-check the size and model number in order to make sure it is similar to the one you are going to replace.
Warnings Sony battery should be replaced
- The laptop will not turn on when not connected to the charger
- The battery gets puffy and looks like it will explode
- The laptop lasts under ten minutes while unplugged
