Acer Extensa 7220 Battery
Your Acer Extensa 7220 battery makes your laptop portable so as to work or play anywhere you please. It is OK to buy a battery with more milliamps, 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. The more power the battery has, the longer you will be able to use the laptop on one charge. Not all batteries are the same, make sure and double-check the model number and compare it to the old one.
What are the clues to watch out for to know my battery is dying?
- The laptop lasts under ten minutes while unplugged
- The Acer laptop will not turn on at all when unplugged
- The battery has its case swollen and looks like it will explode
