GOLDIX L16C4PB1 L16L4PB1 L16M4PB1 laptop battery 7.68V 6080mAh 48Wh

GOLDIX 48Wh lithium-ion replacement

This 7.68V 6080mAh lithium-ion battery replaces the original pack in Lenovo Yoga 720-13IKB and Yoga 730-13IKB ultraportables. It matches the factory voltage and capacity so the laptop reports correct charge levels. The black housing fits the existing bay without modification. Owners of listed part numbers 5B10M52739 or 2ICP4/43/110-2 can install it directly.

Lithium-ion chemistry and fixed voltage

Lithium-ion cells deliver stable output at 7.68V but degrade with heat and deep discharge cycles. The pack has no user-serviceable cells and cannot be upgraded to a higher capacity within the same chassis. Runtime depends on screen brightness, workload and power-profile settings. Users who need all-day operation away from mains power should carry a compatible charger.

Replaces L16C4PB1 L16L4PB1 L16M4PB1 packs

This unit substitutes the original L16C4PB1, L16L4PB1 and L16M4PB1 batteries when they no longer hold sufficient charge. The swap is worthwhile when the laptop shuts down unexpectedly or reports a permanent capacity loss. It does not add extra watt-hours beyond the 48Wh design, so heavier workloads will still require external power.
