Sony VGN-SR290 Battery
Your Sony VGN-SR290 battery allows you to move freely about which gives you the opportunity to use it inside, outside or anywhere your heart desires. Not all batteries are the same, be sure to check the size and model number in order to make sure it is similar to the old battery. More amps in a battery basically means the longer you will be able to use the laptop on a single charge. 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.
Some clues of a declining Sony battery
- The unit refuses to turn on when it is not plugged in
- The battery gets puffy and looking like it is going to burst
- The laptop lasts under ten minutes while using the battery only
