Compatible replacement battery

This 4 cell lithium-ion unit replaces the original power pack in ThinkPad X1 Yoga fourth and fifth generation models and also fits X1 Carbon seventh and eighth generation laptops. It matches OEM part numbers L18M4P72, L18C4P71, SB10K97644 and 02DL006 for direct installation.

Voltage and capacity limits

The pack delivers 15.36 volts and 3230 milliampere-hours from its four cells, so runtime is fixed by that energy rating and cannot be extended without a higher-capacity design. Users who need longer unplugged time must carry a spare or use an external power bank.

Four-cell form factor

The battery uses a four-cell layout that determines its physical thickness and weight; machines designed for a different cell count will not accept this module. Buyers whose laptop requires a three-cell or six-cell pack must select the correct alternative.

Questions about this item

Should I pick the 4-cell 3230mAh version or a higher-capacity option?

This listing is the 4-cell 3230mAh pack rated at 15.36V; no higher-capacity variant is offered here.

What runtime does the 15.36V 3230mAh rating actually give in a ThinkPad X1 Yoga 4th or 5th Gen?

The 15.36V 3230mAh rating sets the energy capacity; real-world runtime depends on screen brightness, workload and power settings.

Does the L18M4P72 connector and 15.36V spec work with the internal charging circuit of an X1 Carbon 7th or 8th Gen?

Yes — the pack matches OEM parts L18M4P72, L18C4P71, SB10K97644 and 02DL006, so it fits and charges in those models.
