57 Wh 15.36 V replacement battery

This lithium-ion battery replaces the original power pack in ThinkPad T14s Gen 3 and Gen 4 ultrabooks. It delivers 57 Wh at 15.36 V and fits the black chassis without modification. The unit ships new and carries a 12-month warranty from the supplier.

Voltage and capacity limits

The 15.36 V nominal output and 57 Wh capacity are fixed by the cell chemistry and form factor. Systems that require a different voltage or a higher watt-hour rating will not operate correctly with this pack. No firmware or hardware adaptation can change those electrical boundaries.

Replaces L21 and SB part numbers

The battery substitutes Lenovo part numbers L21B4P71, L21M4P75, L21C4P73, L21L4P73, L21D4P74 and the corresponding SB and 5B codes listed by the supplier. Upgrading makes sense when the original pack no longer holds a useful charge or shows swelling. It does not add runtime beyond the original 57 Wh specification.

Questions about this item

Which part number matches my ThinkPad T14s Gen 3 or Gen 4?

The battery replaces Lenovo part numbers L21B4P71, L21M4P75, L21C4P73, L21L4P73 and L21D4P74, covering ThinkPad T14s Gen 3 types 21BR, 21BS, 21CQ, 21CR and Gen 4 types 21F6, 21F7, 21F8, 21F9.

What does the 57 Wh rating deliver in daily use on a T14s?

At 15.36 V the 57 Wh cell provides the same energy capacity as the original Lenovo battery, giving comparable run time for typical office workloads on ThinkPad T14s Gen 3 and Gen 4 systems.

What connector standard does this battery use and what does it limit?

It uses the proprietary Lenovo internal battery connector for the T14s Gen 3 and Gen 4 chassis, so it fits only those models and cannot be adapted to other laptop families.
