Lenovo ThinkPad A21M Battery
Your Lenovo ThinkPad A21M battery makes your laptop portable so as to work or play wherever you fancy. The more power the battery has, the longer you will be able to use the laptop when fully charged. Not all batteries are the same, make sure and double-check the physical connection and size and compare it to the old one. Getting a battery with a higher amp rating is OK, it just means the battery will go further on a single charge. What is truly important is the physical size of the battery as well as the connection.
What warnings are present when my primary battery is about to go out?
- The laptop does not run longer than one hour before it dies
- The Lenovo laptop will not turn on when not connected to the charger
- The laptop battery is puffed up and looks like it will explode
