Sony VPCY21CGX Battery
Your Sony VPCY21CGX battery allows you to move freely about so that you can use it inside, outside or anywhere your heart desires. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old battery. It is OK to buy a battery with more milliamps, as it suggests the battery will last a bit longer on one charge. What is truly important is the actual size of the battery and the connection it has. More amps in a battery basically means the longer you will be able to use the laptop when fully charged.
Warnings to watch for in a bad primary battery
- The laptop lasts less than an hour before it dies
- The battery is puffed up and looking like it is going to burst
- The unit refuses to turn on when it is not plugged in

Make sure to try and order parts from a site you know if you purchase through a website. It is in your best interest to re-check the model number so you order the correct battery replacement. Your Sony VPCY21CGX laptop will love you more for buying the right way!
