Sony VGN-CS308J Battery
Your Sony VGN-CS308J battery allows you to move freely about so as to work or play wherever you fancy. It is OK to buy a battery with more milliamps, 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. Not all batteries are the same, make sure and double-check the size and model number in order to make sure it is similar to the old one. The larger the battery, the longer it will last on a single charge.
