Sony VPCEA390X Battery
Your Sony VPCEA390X battery makes your laptop portable which gives you the opportunity to use it where you want. Getting a battery with a higher amp rating is OK, because it simply implies that the battery will last longer. What is important is the connection type and physical size of the battery. More amps in a battery basically means the longer it will last on a single charge. Because no battery is the same, be sure to check the size and model number in order to make sure it is similar to the old battery.
Main clues your battery is not going to last much longer
- The laptop does not turn on when not connected to the charger
- The battery is puffed up like its about to burst
- The laptop lasts under 20 minutes before it shuts itself down
