Sony VGN-BZ570 Battery
Your Sony VGN-BZ570 battery makes your laptop portable so as to work or play anywhere you please. Buying a battery with a higher milliamp rating is fine, it simply means it is a stronger battery. What is important is the connection type and physical size of the battery. 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 one you are going to replace. More amps in a battery basically means the longer it will last when fully charged.
Important clues of an inadequate li-ion battery
- The laptop lasts less than an hour while unplugged
- The unit will not boot up when not connected to the charger
- The laptop battery gets puffy and looking like it is going to burst
