Replacement battery for ThinkPad T14s Gen 2

This lithium-ion battery replaces the original power cell in compatible Lenovo ThinkPad T14s Gen 2 laptops from 2021. It restores mobile operation when the factory pack no longer holds a useful charge. The unit ships new in black and carries a 12-month warranty.

Capacity and voltage match the original spec

The pack delivers 57 Wh at 15.36 V, matching the energy and voltage ratings Lenovo specified for this model. Several part numbers including L20C4P72, L20D4P72, L20L4P72 and L20M4P72 are interchangeable, so the exact variant shipped may vary while remaining compatible.

Runs at standard laptop thermals with no extra noise

As a direct-fit internal battery it produces no audible sound and adds no active cooling load. Power draw follows the laptop's own management system, so thermal behaviour remains identical to the original component during normal use.

Questions about this item

How long will the 57Wh capacity actually run my ThinkPad T14s Gen 2?

The 57Wh lithium-ion pack matches the original specification, so typical office workloads should deliver a full working day on a single charge.

Does the 15.36V rating mean I must match that exact voltage?

The supplier notes that L20C4P72, L20D4P72, L20L4P72 and L20M4P72 are cross-compatible despite voltage differences, so any shipped variant will work.

Will this battery fit inside my T14s Gen 2 without modification?

Yes, it replaces part numbers 41CP5/67/67 and the SB10W and 5B10W series, which are the exact internal packs for the listed ThinkPad models.
