Sony VGN-CR390 Battery
Your Sony VGN-CR390 battery allows you to move freely about so as to work or play anywhere you please. The larger the battery, the longer it will last on one charge. Buying a battery with a higher milliamp rating is fine, as it just means the battery will last longer. What really is critical to a battery fitting your laptop is the actual size of the battery and the connection it has. Not all batteries are the same, make sure and double-check the part number of the new battery and compare it to the old battery.
How can I tell if my battery is dying?
- The laptop lasts less than an hour before it shuts itself down
- The laptop battery has its case swollen and looks like it will explode
- The laptop will not turn on at all when unplugged
