Compatible Lenovo Yoga Book Battery

This replacement battery fits the Lenovo Yoga Book YB1 series including models YB1-X90F, YB1-X90L, YB1-X91F, YB1-X91L and YB1-X91X. It replaces original part numbers L15C2P31 and SB18C04740. The lithium-polymer cell delivers 8.5 Ah capacity in a black housing.

Lithium-Polymer Chemistry Constraints

Lithium-polymer cells require correct voltage matching and physical alignment with the Yoga Book chassis. Installation must follow the device service guide to avoid connector damage. The battery is not user-serviceable beyond standard replacement procedures.

8.5 Ah Capacity Decides Runtime

The 8.5 Ah rating determines how long the Yoga Book operates between charges. Buyers needing longer runtime than the original cell provided should verify the voltage matches before purchase. This unit does not increase capacity beyond the specified 8.5 Ah.
