Sony VPCSA390X Battery
Your Sony VPCSA390X battery allows you to move freely about so that you can use it inside, outside or anywhere your heart desires. It is OK to buy a battery with more milliamps, it just means the battery will go further on a single charge. 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 when fully charged. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old one.
Symptoms the primary battery will eventually need to be replaced
- The battery is puffed up and looks like it will explode
- The laptop lasts way less than it used to while unplugged
- The unit does not turn on when not connected to the charger
