Acer Aspire 4220 Battery
Your Acer Aspire 4220 battery makes your laptop portable so as to work or play anywhere in the house or even outdoors! Buying a battery with a higher milliamp rating is fine, as it suggests the battery will last a bit longer on one charge. What is truly important is the physical size of the battery as well as the connection. Not all batteries are the same, be sure to check the size and model number in order to make sure it is similar to the old battery. More amps in a battery basically means the longer it will last when fully charged.
