Genuine ThinkPad T14s Battery

This lithium-ion battery is built as a direct replacement for Lenovo ThinkPad T14s Gen 3 and Gen 4 systems. It restores original run-time for mobile professionals who need reliable power away from a desk.

15.36 V Li-ion voltage constraint

The pack operates at a fixed 15.36 volts, so it only fits laptops designed for that exact potential. Systems expecting a different voltage will not recognise the pack or may refuse to charge it.

57 Wh capacity for daily workloads

A 57 watt-hour rating delivers several hours of typical office use on a single charge. Heavier workloads such as sustained video rendering or large compiles will exhaust the pack more quickly.
