Lenovo ThinkPad A22M Battery
Your Lenovo ThinkPad A22M battery makes your laptop portable so that you can use it wherever you fancy. The larger the battery, the longer it will last on a single charge. Because no battery is the same, be sure to check the model number and compare it to the old one. It is OK to buy a battery with more milliamps, as it suggests the battery will last a bit longer on one charge. What is truly important is the connection type and physical size of the battery.
Key signs to watch for in a bad primary battery
- The laptop refuses to turn on when it is not plugged in
- The laptop does not last longer than 45 minutes before it shuts itself down
- The battery is puffed up and looking like it is going to burst
