Sony VGN-Z690 Battery
Your Sony VGN-Z690 battery makes your laptop portable so that you can use it where you want. It is OK to buy a battery with more milliamps, it just means the battery will go further on a single charge. What is truly important is the connection type and physical size of the battery. Not all batteries are the same, make sure and double-check the physical connection and size and compare it to the old battery. More amps in a battery basically means the longer it will last on a single charge.
Clues of an inadequate Sony battery
