Replacement battery for ThinkPad T14 and P14s

This new lithium-ion battery replaces part numbers L21C4P71, L21L4P71, L21M4P71 and L21M4P72 in ThinkPad T14 Gen 3, T14 Gen 4, P14s Gen 3 and P14s Gen 4 laptops. It delivers 52.5 Wh at 15.44 V or 15.48 V and comes in black. The pack is a direct swap for the original internal battery.

Who this suits and who should look elsewhere

Owners of the listed ThinkPad models who need a fresh 52.5 Wh cell will find a compatible fit. Users with other ThinkPad series, different generation numbers, or machines that require a higher or lower watt-hour rating cannot use this unit. Buyers wanting an external power bank or a larger capacity internal battery should consider a different product.

Deciding specification: 52.5 Wh capacity

The single figure that determines fit is the 52.5 Wh rating matched to the 15.44 V/15.48 V voltage. Confirm that your original battery shows the same watt-hour value and one of the listed part numbers before ordering.
