Replacement Battery for ThinkPad X1 Yoga 3rd Gen

This 15.36V lithium-ion pack supplies 54Wh and 3520mAh to compatible ThinkPad X1 Yoga 3rd Gen models. It matches the original L17M4P71, L17C4P71 and L17M4P73 part numbers listed by the supplier. The unit ships new and is ready for installation without modification.

Voltage and Capacity Limits

The fixed 15.36V output and 54Wh energy rating define the maximum run time available from a single charge. Capacity cannot exceed the stated 3520mAh, so workloads drawing sustained high current will deplete the pack faster than lighter tasks. No higher-capacity variant is offered under this model.

Black Polymer Housing with Original Mounting

The black casing uses the same screw points and connector layout as the factory battery, so it seats securely in the existing bay. Li-ion cells and the integrated PCB are assembled to meet the declared capacity without shortfall. Following the supplier's conditioning cycle of two to three full charge-discharge rounds helps stabilise runtime.
