Sony VPCZ21BGX Battery
Your Sony VPCZ21BGX battery allows you to move freely about which gives you the opportunity to use it wherever you fancy. Buying a battery with a higher milliamp rating is fine, as it signifies that the battery can last for a longer period of time on one charge. What is truly important is the actual size of the battery and the connection it has. Not all batteries are the same, be sure to check the model number and compare it to the old one. The larger the battery, the longer you will be able to use the laptop on a single charge.
