GreenTech 90 Wh ThinkPad P16v battery
This GreenTech replacement battery fits Lenovo ThinkPad P16v Gen 1 and Gen 2 models including 21FC, 21FD, 21FE, 21FF, 21KX and 21KY. It is a new 4-cell lithium-ion pack rated at 15.52 V and 5799 mAh. The unit replaces OEM part numbers L22C4P71, L22M4P71, SB11H56274, SB11H56275 and the 5B11 series.
Who this suits and who it does not
It suits owners of the listed ThinkPad P16v machines who need a direct 90 Wh swap. It will not work in other ThinkPad families, smaller ultraportables or laptops that require a different voltage or connector. Buyers with a different chassis or a lower-capacity original battery should look elsewhere.
90 Wh capacity decides fit
The 90 Wh rating matches the factory specification for the compatible P16v models. A lower-watt-hour pack would reduce run time while a higher one would not fit the bay. Verify the 15.52 V and 5799 mAh figures against your original battery before ordering.

Questions about this item
What voltage does the L22M4P71 battery deliver, and what does that limit in practice?
The battery outputs 15.52 V, which matches the ThinkPad P16v Gen 1 and Gen 2 power rail and caps the maximum charge voltage the system will accept.
What are the physical dimensions of the 90 Whr pack, and which chassis does it fit?
The pack measures 13 x 3.2 x .5 and fits the ThinkPad P16v Gen 1 (21FC, 21FD, 21FE, 21FF) and Gen 2 (21KX, 21KY) internal battery bay.
How is the battery installed, and which step do people often miss?
Remove the base cover, disconnect the old pack, connect the new L22M4P71 connector firmly until it clicks, then re-secure the cover screws — many forget to reconnect the cable fully before closing the case.
