Sony VGN-AR290G Battery
Your Sony VGN-AR290G battery makes your laptop portable which gives you the opportunity to use it anywhere you please. Not all batteries are the same, make sure and double-check the model number and compare it to the old battery. The larger the battery, the longer it will last on a single charge. Buying a battery with a higher milliamp rating is fine, because it simply implies that the battery will last longer. What is important is the physical size of the battery as well as the connection.
Major signs the li-ion battery will die soon
- The laptop battery has its case swollen and looking like it is going to burst
- The laptop will not boot up when it is not plugged in
- The laptop lasts less than an hour before it shuts itself down
