Lenovo ThinkPad T440s 20AQ006HUS Battery
Your Lenovo ThinkPad T440s 20AQ006HUS battery makes your laptop portable so that you can use it where you want. Because no battery is the same, make sure and double-check the model number and compare it to the old one. More amps in a battery basically means the longer you will be able to use the laptop on a single charge. 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 connection type and physical size of the battery.
Indications poorly running li-ion battery
- The laptop lasts way less than it used to while using the battery only
- The unit does not turn on when it is not plugged in
- The battery gets puffy and looking like it is going to burst
