Compatible replacement battery
This Total Micro Technologies 5B10W51877-TM is a new 4-cell laptop battery built for the Lenovo ThinkPad T14s Gen 3 and T14s Gen 4. It restores mobile power when the original pack no longer holds a charge.
57WHr 15.36V capacity
The single specification that decides fit is the 57WHr 15.36V rating combined with the 4-cell layout. Only ThinkPad T14s Gen 3 or Gen 4 models that accept this exact voltage and capacity will work correctly.
Suits owners of supported ThinkPads
Buyers with a ThinkPad T14s Gen 3 or Gen 4 needing a direct swap can use this pack. Owners of other ThinkPad series, different generations, or laptops requiring a different cell count or voltage should look elsewhere.

Questions about this item
What does the 57WHr rating mean for daily use on a ThinkPad T14s?

It uses the proprietary Lenovo ThinkPad battery connector designed for the T14s Gen 3 and Gen 4 chassis.
