Sony VGN-CR520E Battery
Your Sony VGN-CR520E battery allows you to move freely about so that you can use it where you want. More amps in a battery basically means the longer it will last when fully charged. Not all batteries are the same, be sure to check the physical connection and size and compare it to the old battery. Getting a battery with a higher amp rating is OK, as it signifies that the battery can last for a longer period of time on one charge. What is important is the physical size of the battery as well as the connection.
