Questions about this item

Which ThinkPad models accept the KingSener E555 battery with part numbers 45N1759 45N1758 45N1760?

The E555 replaces the original battery in ThinkPad E550, E550C, E560 and E565C laptops. It matches the listed Lenovo part numbers and fits the same bay dimensions.

Will the 10.8V 48WH E555 charge correctly with the original 45W or 65W ThinkPad AC adapter I already own?

Yes. The battery operates at 10.8V and is designed to charge from the standard ThinkPad slim-tip adapter supplied with E550, E550C, E560 and E565C systems.

After the first few charge cycles, how can I verify the E555 is delivering its rated 4400mAh capacity?

Fully charge, then run the laptop on battery until it hibernates. Check the reported full-charge capacity in the OS power report; it should read at or above 48WH.
