Sony PCG-GRT290Z Battery
Your Sony PCG-GRT290Z battery allows you to move freely about so as to work or play anywhere you please. Because no battery is the same, make sure and double-check the size and model number in order to make sure it is similar to the old one. It is OK to buy a battery with more milliamps, 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 more power the battery has, the longer it will last when fully charged.
Red flags Sony battery is failing
- The laptop is unable to boot up when not connected to the charger
- The battery has its case swollen and looking like it is going to burst
- The laptop lasts way less than it used to before it shuts itself down
