Sony PCG-NV290 Battery
Your Sony PCG-NV290 battery makes your laptop portable so that you can use it anywhere you please. Buying a battery with a higher milliamp rating is fine, it just means the battery will go further on a single charge. What is important is the actual size of the battery and the connection it has. More amps in a battery basically means the longer it will last 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 old one.
Chief elements of an inadequate li-ion battery
- The laptop lasts way less than it used to while unplugged
- The laptop battery is puffed up like its about to burst
- The laptop will not boot up when it is not plugged in
