Sony VGN-NR290E Battery
Your Sony VGN-NR290E battery makes your laptop portable which gives you the opportunity to use it inside, outside or anywhere your heart desires. The larger the battery, the longer you will be able to use the laptop when fully charged. Because no battery is the same, be sure to check the part number of the new battery and compare it to the old one. Buying a battery with a higher milliamp rating is fine, it just means the battery will go further on a single charge. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection.
Elements of an inadequate li-ion battery
- The Sony laptop does not turn on when it is unplugged
- The laptop does not last longer than 45 minutes before it dies
- The laptop battery gets puffy and looks like it will explode
