Sony VGN-CR220E Battery
Your Sony VGN-CR220E battery allows you to move freely about which gives you the opportunity to use it where you want. Because no battery is the same, be sure to check the size and model number in order to make sure it is similar to the old battery. More amps in a battery basically means the longer you will be able to use the laptop on a single charge. 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 truly important is the physical size of the battery as well as the connection.
