Sony VGN-NW320F Battery
Your Sony VGN-NW320F 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 physical size of the battery as well as the connection. The larger the battery, the longer it will last on one charge. Because no battery is the same, be sure to check the part number of the new battery and compare it to the one you are going to replace.
