Replacement battery for ThinkPad P50 P51 P52

This 77+ lithium-ion battery replaces the original Lenovo packs used in ThinkPad P50, P51 and P52 series mobile workstations. It delivers 90 Wh at 11.25 V and matches the black finish of the factory unit. The part number SB10H45078 cross-references to Lenovo numbers 00NY490 through 00NY493 and 01AV477, 01AV495, 01AV496. Builders who need a higher-capacity option or a different form factor cannot use this pack.

Voltage and capacity limits

The cell chemistry is fixed at 11.25 V and 90 Wh, so the pack cannot be re-configured for other voltage rails or extended runtime beyond its rated capacity. It is not compatible with ThinkPad models outside the P50, P51 and P52 series, and it will not fit systems that require a different physical outline or connector keying. Users who need hot-swap capability or a secondary battery bay must look elsewhere.

Installation notes

The battery ships as a single unit with no tools or mounting hardware included. Installation requires removing the bottom cover of the notebook, disconnecting the old pack and securing the new one in the same location. Common issues include failing to seat the connector fully, which prevents the system from recognising the battery, and forgetting to reset the battery gauge in the BIOS after the swap.
