Sony VPCF12JFX Battery
Your Sony VPCF12JFX battery makes your laptop portable so that you can use it anywhere you please. Getting a battery with a higher amp rating is OK, it simply means it is a stronger battery. What is important is the physical size of the battery as well as the connection. Because no battery is the same, make sure and double-check the physical connection and size and compare it to the old battery. The larger the battery, the longer it will last on one charge.
Clues of a bad primary battery
- The battery is puffed up and looks like it will explode
- The laptop does not run longer than one hour while unplugged
- The laptop will not turn on when it is not plugged in
