Sony VGN-BZ579TBB Battery
Your Sony VGN-BZ579TBB battery makes your laptop portable which gives you the opportunity to use it wherever you fancy. Buying a battery with a higher milliamp rating is fine, because it simply implies that the battery will last longer. What really is critical to a battery fitting your laptop is the connection type and physical size of the battery. Not all batteries are the same, be sure to check the part number of the new battery and compare it to the old one. The more power the battery has, the longer it will last when fully charged.
What are some indications that my li-ion battery is in need of a replacement?
- The laptop does not last longer than 45 minutes while unplugged
- The battery has its case swollen like its about to burst
- The Sony laptop is unable to boot up when not connected to the charger
