Sony VGN-B55C Battery
Your Sony VGN-B55C battery makes your laptop portable so that you can use it where you want. Getting a battery with a higher amp rating is OK, because it simply implies that 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 more power the battery has, the longer you will be able to use the laptop on one charge. Not all batteries are the same, be sure to check the physical connection and size and compare it to the old one.
