Replacement battery for ThinkPad T14 and P14s

This 11.52V lithium-ion pack replaces the original Lenovo battery in ThinkPad T14 Gen 1, T14 Gen 2, T490, T495, P43S, P14s Gen 1 and P14s Gen 2 models. It matches part numbers L18M3P73, SB10K97646, 02DL008 and the related L18C3P72, L18M4P73, L18M4P74 series. Buyers who need a different voltage or a higher capacity pack will not be served by this unit.

Three-cell construction

The battery uses three Li-ion cells in a black housing and connects through the regular internal ThinkPad interface. No adapters or cable modifications are required during installation. The physical layout follows the original design so the laptop chassis closes normally. Users who prefer an external hot-swap battery or a modular slice battery cannot use this internal pack.

Rated at 51 Wh with low self-discharge

The 51 Wh rating delivers typical mobile runtime for the supported ultraportables. Lithium-ion chemistry keeps self-discharge low when the machine is stored unplugged. Operating temperature stays within normal laptop limits because the pack draws the same current profile as the factory unit. There is no active cooling and no additional power draw beyond the cells themselves.
