Sony VGN-Z590 Battery
Your Sony VGN-Z590 battery allows you to move freely about so that you can use it anywhere you please. Not all batteries are the same, make sure and double-check the model number and compare it to the old battery. The more power the battery has, the longer you will be able to use the laptop when fully charged. Buying a battery with a higher milliamp rating is fine, as it suggests the battery will last a bit longer on one charge. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection.
How do you know when your Sony battery has to be replaced?
- The Sony laptop will not turn on while not connected to the AC adapter
- The laptop does not last longer than 45 minutes before it dies
- The laptop battery gets puffy and looks like it will explode
