GreenTech 57 Wh replacement battery

This GreenTech battery replaces the original 5B11H56383 pack in Lenovo ThinkPad X1 Carbon Gen 12 and X1 2-in-1 Gen 9 laptops. It delivers 11.7 V and 57 Wh from a three-cell lithium-ion design. The unit is brand new and carries CE, FCC and RoHS safety certifications.

Fits 12th Gen Carbon and 9th Gen 2-in-1

The battery matches the listed 21KC, 21KD, 21KE and 21KF chassis codes and the extensive sub-model list supplied by the manufacturer. It will not suit earlier Carbon generations, other ThinkPad families or non-Lenovo ultrabooks. Buyers needing a different voltage or a higher capacity pack should look elsewhere.

11.7 V three-cell lithium-ion chemistry

The 11.7 V nominal voltage and three-cell lithium-ion construction are the decisive electrical characteristics for compatibility. The pack measures 11.2 x 3.9 x 0.25 inches and weighs 0.75 lb, matching the original form factor. Verify the part number against your service manual before ordering.
