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.

Questions about this item

Does the battery arrive ready to install or do I need extra tools or cables?

The battery is a complete 3-cell lithium-ion unit measuring 11.2 x 3.9 x 0.25 inches and weighing 0.75 lb. It slots directly into the X1 Carbon Gen 12 or X1 2-in-1 Gen 9 chassis with no additional cables or tools required.

Which part number matches my ThinkPad — 5B11H56383, 5B11H56384 or 5B11H56385?

All three numbers (plus 5B11H56386, L22B3P73, L22C3P76, L22D3P77, L22M3P77, SB11H56285, SB11H56286 and SB11H56287) are listed as interchangeable OEM replacements, so any of them will fit the compatible models.

What does the 57 Wh rating mean for daily runtime on my X1 Carbon Gen 12?
