Replacement battery for ThinkPad P53

This lithium-ion pack is built to replace the original power cell in Lenovo ThinkPad P53 mobile workstations. It ships new and matches the form factor required by the listed part numbers. Buyers who need a battery for a different ThinkPad series or a non-Lenovo laptop cannot use this unit.

90 Wh capacity at 11.25 V

The cell delivers ninety watt-hours at eleven point two five volts, which defines the total energy available per charge. Runtime scales with the workload and power profile of the host machine, so heavy compute tasks will drain it faster than light office use. No higher-capacity alternative exists within this exact part-number family.

Part-number match decides fit

Compatibility is limited to the specific ThinkPad P53 models and the replacement part numbers L18C6P90, L18M6P90, 02DL028, 02DL029, SB10K97664 and SB10K97665. Verify the original battery label against this list before ordering; a mismatch means the battery will not seat or communicate correctly.
