Sony VGN-P799L Battery
Your Sony VGN-P799L 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 one. The larger the battery, the longer you will be able to use the laptop when fully charged. It is OK to buy a battery with more milliamps, as it suggests the battery will last a bit longer on one charge. What is truly important is the connection type and physical size of the battery.
Signs to watch for in a bad li-ion battery
- The battery has its case swollen like its about to burst
- The laptop is unable to boot up at all when unplugged
- The laptop lasts under 20 minutes before it shuts itself down
