Sony VGN-TT290 Battery
Your Sony VGN-TT290 battery allows you to move freely about so as to work or play inside, outside or anywhere your heart desires. It is OK to buy a battery with more milliamps, as it suggests the battery will last a bit longer on one charge. What really is critical to a battery fitting your laptop is the connection type and physical size of the battery. Because no battery is the same, make sure and double-check the size and model number in order to make sure it is similar to the one you are going to replace. More amps in a battery basically means the longer you will be able to use the laptop on a single charge.
Warnings the primary battery should be replaced
- The laptop battery gets puffy like its about to burst
- The laptop lasts under 20 minutes while using the battery only
- The Sony laptop refuses to turn on when it is unplugged
