ThinkPad X1 Carbon 5th Gen replacement battery

This new GreenTech lithium-polymer battery replaces the original Lenovo units for the 2017 ThinkPad X1 Carbon 5th Gen. It matches the OEM part numbers SB10K97587, SB10K97586, SB10K97588, 01AV429, 01AV430 and 01AV431. The pack is built to the same 11.52 V specification and carries CE, FCC and RoHS safety certifications.

57 Wh capacity decides runtime

The single figure that determines whether this pack will meet your needs is the 57 Wh energy rating, equivalent to 4947 mAh at 11.52 V. If your workload demands more stored energy than 57 Wh, this battery will fall short regardless of its voltage or cell count. Buyers who need a higher capacity pack for longer unplugged sessions should look for a larger Wh rating.

Three-cell polymer holds voltage under load

With three lithium-polymer cells the battery maintains a stable 11.52 V output during sustained discharge rather than sagging after a short burst. Low self-discharge and built-in circuit protection keep current steady over long work periods. The chemistry is tested for consistent performance across repeated charge cycles.

Questions about this item

What does the 57 Wh rating mean for daily runtime on my ThinkPad X1 Carbon 5th Gen?

The 57 Wh capacity matches the original battery specification, so you should see the same typical runtime you had when the laptop was new.

Does the 11.52 V output work with the ThinkPad's internal charging circuit without modification?

Yes, the 11.52 V rating is identical to the OEM design and the laptop's charging controller accepts it directly.

Will the three-cell polymer pack fit the internal battery bay of the 20HQ and 20HR chassis variants?

The pack is built to the same three-cell form factor as the original SB10K97587 and seats in the bay without adapters.
