Sony PCG-FX220K Battery
Your Sony PCG-FX220K battery makes your laptop portable which gives you the opportunity to use it where you want. Buying a battery with a higher milliamp rating is fine, it just means the battery will go further on a single charge. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection. More amps in a battery basically means the longer it will last when fully charged. Not all batteries are the same, be sure to check the part number of the new battery and compare it to the one you are going to replace.
