Sony VGN-SZ450N Battery
Your Sony VGN-SZ450N battery allows you to move freely about so as to work or play wherever you fancy. Because no battery is the same, be sure to check the physical connection and size and compare it to the old one. Buying a battery with a higher milliamp rating is fine, as it just means the battery will last longer. What is truly important is the physical size of the battery as well as the connection. The larger the battery, the longer it will last when fully charged.
How do you know when your li-ion battery is about to stop working?
- The Sony laptop refuses to turn on while unplugged
- The battery gets puffy and looks like it will explode
- The laptop does not run longer than one hour while unplugged
