  • TypeBattery
  • Replacement ready for multiple Lenovo Yoga models

Ready for Lenovo Yoga 4S and 900S

This lithium-polymer battery replaces the original 5B10J50660, 5B10J50662, 5B10J66116 and L15M4P20 packs. It fits Yoga 4S, Yoga 900S, Yoga 900S 12ISK and Yoga 900S-12ISK models including the 80ML001WGE, 80ML001XGE, 80ML001YGE and 6Y75 variants. The black casing matches the chassis colour of those ultraportables.

Direct internal fit with no extra parts

The pack slides into the existing battery bay using the original connector and screw points. No adapter cables, mounting brackets or firmware tools are required. Its 267.78 x 127.70 x 3.35 mm footprint occupies the same volume as the factory unit, leaving all ports, vents and the keyboard deck unchanged.

Steady 7.4 V output through long sessions

Rated at 6900 mAh and 51.06 Wh, the cell maintains a stable voltage during extended workloads such as video playback or document editing. Li-Polymer chemistry resists voltage sag better than older chemistries, so the laptop stays powered until the charge is genuinely depleted rather than cutting out early.

Questions about this item

How long will the 51.06 Wh capacity last during a full day of continuous use?

The 51.06 Wh rating gives the total energy stored; actual run time depends on the laptop's power draw, which varies by workload and screen brightness.

Does the Li-Polymer 7.4V 6900mAh cell generate noticeable heat when the Yoga 900S runs all day?

Li-Polymer chemistry runs cooler than older types, but any battery warms under sustained load; the slim 3.35 mm profile leaves little room for airflow inside the chassis.

Which Lenovo Yoga models are confirmed compatible with part numbers 5B10J50660, 5B10J50662 and 5B10J66116?

The battery fits Yoga 4S, Yoga 900S, Yoga 900S 12ISK and Yoga 900S-12ISK variants including 80ML001WGE, 80ML001XGE, 80ML001YGE and 6Y75.
