Sony PCG-GRX770 Battery
Your Sony PCG-GRX770 battery makes your laptop portable so that you can use it where you want. Getting a battery with a higher amp rating is OK, as it just means 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. Because no battery is the same, be sure to check the part number of the new battery and compare it to the old battery. The more power the battery has, the longer it will last on one charge.
What are the signs that the battery has gone bad?
- The battery is puffed up and looks like it will explode
- The laptop will not boot up while not connected to the AC adapter
- The laptop lasts less than half an hour before it dies
