Acer TravelMate 7720 Battery
Your Acer TravelMate 7720 battery makes your laptop portable so as to work or play inside, outside or anywhere your heart desires. 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 really is critical to a battery fitting your laptop is the connection type and physical size of the battery. 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 it will last on one charge.
