Sony VPCEA490X Battery
Your Sony VPCEA490X battery makes your laptop portable which gives you the opportunity to use it where you want. It is OK to buy a battery with more milliamps, as it suggests the battery will last a bit longer on one charge. What is important is the actual size of the battery and the connection it has. Because no battery is the same, make sure and double-check the physical connection and size and compare it to the old battery. More amps in a battery basically means the longer it will last on a single charge.
Symptoms your battery needs replacing
- The laptop battery gets puffy and looking like it is going to burst
- The laptop does not run longer than one hour before it shuts itself down
- The unit refuses to turn on when it is unplugged
