Sony PCG-GR300 Battery
Your Sony PCG-GR300 battery makes your laptop portable so that you can use it wherever you fancy. Getting a battery with a higher amp rating is OK, 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 connection type and physical size of the battery. The larger the battery, the longer it will last on one charge. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the one you are going to replace.
Important signs the primary battery has very little life left
- The laptop battery has its case swollen like its about to burst
