Replacement Battery for ThinkPad T and P Series

This 72Wh lithium-ion battery replaces part 01AV427 in Lenovo ThinkPad T470, T480, T570, T580, P51S, P52S, A475, A485 and TP25 models. It delivers 6600mAh at 11.1V to restore mobile runtime for professionals who rely on these systems daily.

Sustained Operation with Circuit Protection

A built-in protection board manages charge and discharge cycles to prevent over-voltage, over-current and short-circuit events during extended work sessions. A++ grade cells maintain stable output and low self-drain so the pack stays ready after periods of storage.

72Wh Capacity Decides Fit

The 72 watt-hour rating determines whether this unit matches the original specification for your ThinkPad. Buyers needing a lower-capacity 48Wh or 57Wh pack for thinner chassis configurations should verify the part number before ordering.
