Replacement battery for ThinkPad X1 Carbon 5th Gen

This 4950 mAh lithium-ion unit is built as a direct replacement for the Lenovo ThinkPad X1 Carbon 5th Gen. It restores mobile power to a compatible notebook that no longer holds a charge with its original pack. The black three-cell design matches the factory form factor for a straightforward swap.

Capacity and voltage headroom

Rated at 11.52 V and 4950 mAh, the pack delivers the same energy envelope as the original battery. It comfortably supports typical office workloads and media playback on the target laptop. Runtime will decrease under sustained heavy loads or as the cells age through normal charge cycles.

Three-cell lithium-ion chemistry

The battery uses a three-cell lithium-ion construction fixed at 11.52 V. This cell count and voltage combination determines physical fit and electrical compatibility with the X1 Carbon 5th Gen. Systems requiring a different cell count or voltage will not accept this pack.

Questions about this item

Will the 11.52V 4950 mAh battery fit my existing ThinkPad X1 Carbon 5th Gen without any chassis modification?

Yes, the SB10K97587-BTI is built to the original form factor for the ThinkPad X1 Carbon 5th Gen and slots into the same bay as the factory pack.

How can I confirm the new pack is delivering the rated 11.52V and 4950 mAh after I install it?

Use Lenovo Vantage or the BIOS power section to read the reported design capacity and voltage; they should show 4950 mAh and 11.52V when the battery is fully charged.

Does the box include any installation tools or a replacement screw set for the X1 Carbon 5th Gen?

The package contains only the 3-cell lithium-ion battery itself; no screwdrivers, screws or adhesives are supplied.
