86Wh 4-cell replacement battery

This 86Wh lithium-ion pack replaces the original Lenovo battery for ThinkPad T16 Gen 3 and Gen 4 models as well as ThinkPad P16s Gen 4 systems. It delivers 15.44V from four cells and is built to the same physical outline as the OEM part. The unit is new and carries CE, FCC and RoHS safety certifications.

Verify your exact sub-model before ordering

The battery fits a long list of specific machine-type codes including 21MN, 21MQ, 21QN, 21QQ, 21QE, 21QF for the T16 and 21QR, 21QS, 21RX, 21RY for the P16s. Cross-reference the sticker on your current battery or the service tag against this list; other ThinkPad families or earlier generations are not supported. If your device uses a different voltage or cell count, this pack will not work.

Direct swap with no extra cables or software

The package contains only the battery itself; no tools, screws, adapters or driver discs are included. Installation is a mechanical swap — remove the old pack, insert this one, and the system firmware recognises it automatically. Buyers who need a complete service kit or diagnostic utilities will have to source those separately.
