ThinkPad T14 Gen 2 replacement battery

This 57Wh lithium-ion unit is built for the ThinkPad T14 Gen 2 and carries part numbers L21C3PD4, L21D3PD4, L21L3PD4 and L21M3PD4. It operates at 11.52V and comes in black as a direct swap for the original pack.

Owners needing a drop-in replacement for a worn cell

Users with other ThinkPad models or different voltage requirements should verify compatibility before ordering. The pack replaces part numbers SB11E33547, SB11E33545 and 31CP6/54/90, but the supplier notes the list is non-exhaustive.

57Wh capacity for typical mobile workloads

The 11.52V design delivers enough energy for a full day of office tasks, web browsing and video playback on the target laptop. Runtime will fall short for sustained heavy loads such as rendering or extended compile sessions where power draw exceeds the cell's rated capacity.
