Replacement battery for ThinkPad S1 Yoga

This 4-cell lithium-ion pack is built to fit the Lenovo ThinkPad S1 Yoga and matches OEM part numbers 45N1706, 45N1707, 45N1705 and 45N1704. It restores mobile power for owners whose original cell no longer holds a useful charge.

Sustained runtime from a 14.8V 3180mAh pack

The four cells deliver 14.8 volts and 3180 milliampere-hours, providing steady energy during long work sessions away from a wall outlet. Capacity holds up through repeated charge cycles without the sharp drop-off seen in aged originals.

Internal fit with direct connector alignment

Designed as an internal notebook battery, it slides into the S1 Yoga bay and locks to the motherboard connector without adapters or cable routing. The precise moulding matches the chassis latch points, so the laptop closes flush and the trackpad click feels unchanged.

Questions about this item

How much heat does the 14.8V 3180mAh 4-cell battery generate during all-day use?

Lithium-ion cells produce minimal heat under normal loads; the pack runs at 14.8 volts and 3180 mAh, so warmth stays low during typical work sessions.

What must my Lenovo ThinkPad S1 Yoga already have for this 45N1706 replacement to fit and work?

The laptop must use the original 4-cell internal battery with OEM part numbers 45N1704, 45N1705, 45N1706 or 45N1707; no extra cables or adapters are required.

Will the 45N1706 pack charge correctly with the original 45 W ThinkPad charger I still use?

Yes — the 14.8V 3180mAh cell chemistry matches the factory specification, so the existing 45 W charger communicates and charges normally.
