Made for Lenovo Yoga 11 and 11S

This lithium-polymer battery is built as a direct replacement for the Lenovo IdeaPad Yoga 11 and 11S ultrabooks. It matches the original 14.8V, 42Wh, 2840mAh specification so the system recognises it without extra steps. Buyers who need a different voltage or a higher capacity will need another part.

Steady output through a full day

The cell chemistry is chosen for stable voltage across the discharge curve rather than a brief peak. That means the ultrabook keeps its performance level during long work or study sessions instead of throttling when the charge drops. Users who regularly drain a pack in under two hours will not gain extra runtime from this unit.

Cool, quiet and light in normal use

Li-Polymer construction runs cooler than older cylindrical packs, so the chassis stays comfortable on a lap or desk. There are no moving parts, so operation is silent. The slim black shell adds minimal bulk, keeping the Yoga 11 or 11S portable. Anyone expecting a ruggedised or waterproof design should look elsewhere.

Questions about this item

How much heat does the 14.8V 42Wh Li-Polymer battery produce during all-day use?

The battery uses advanced Li-Polymer technology for stable output and efficient charging, which minimises heat generation during extended daily operation.

What must I already own for this L11M4P13 battery to work?

You need a Lenovo IdeaPad Yoga 11 or 11S Ultrabook that accepts the 4ICP4/56/120 form factor; the pack is a direct OEM replacement for those models.

Will this 2840mAh replacement work alongside the original charger I kept from my Yoga 11S?

Yes, the 14.8V 42Wh cell is designed to match the original electrical specification, so your existing Lenovo AC adapter will charge it normally.
