Replacement Battery for ThinkBook 13s and 13x

This 56Wh lithium-ion unit operates at 15.52V and is built new for Lenovo ThinkBook 13s G4 ARB and IAP models. It also fits the ThinkBook 13x G2 IAP and ThinkBook Plus G4 IRU series. The black pack replaces part numbers L21B4PD0, L21C4PD0, L21M4PD0 and the associated SB and 5B service codes.

Compatibility Limits

Buyers with ThinkBook models outside the listed 21AS, 21AR, 21AT and 21JJ type codes cannot use this battery. It is not suitable for laptops requiring a different voltage or connector layout. Users needing a higher capacity pack should look for an alternative specification.

56Wh Capacity Decides Fit

The 56 watt-hour rating at 15.52V is the single figure that confirms whether this part matches the original equipment. Verify the Wh value printed on your existing battery before ordering. A different capacity indicates a different internal cell configuration and will not install correctly.
