Compatible ThinkPad models

This Dr. Battery replacement fits Lenovo ThinkPad T470 T480 T570 T580 P51s P52s A475 A485 and TP25 laptops. It replaces original Lenovo part numbers including 01AV452 01AV423 and the SB10K series. The 2100 mAh lithium polymer cell restores mobile power for business users who need reliable runtime away from a desk.

Lithium polymer voltage and capacity limits

The pack operates at 11.4 V and delivers 2100 mAh for approximately 24 Wh of energy. Lithium polymer chemistry provides stable output but capacity will diminish with charge cycles and age. Runtime varies with workload screen brightness and power management settings so heavy workloads will deplete the charge faster than light office tasks.

Physical fit and connector match

The battery measures 8.0 by 1.5 by 0.8 and weighs 0.4. It is built to the same form factor as the original Lenovo packs so it seats correctly in the battery bay and aligns with the system connector. Buyers whose laptop uses a different battery shape or connector will not be able to install this unit.
