Replacement battery for Lenovo ultraportables

The KingSener L17L3P61 is a 3108 mAh, 11.58 V lithium-ion pack built to fit IdeaPad 320S-13IKB, Yoga 330-11IGM, Yoga 720-12IKB, Flex 6-11IGM and Xiaoxin 7000-13 models. It replaces original part numbers L17M3P61, L17C3P61, 5B10N87357, 5B10N87358, 5B10N87359 and 81AK. The black casing matches the factory aesthetic.

Steady output through a full workday

Rated at 36 Wh, the cell chemistry maintains consistent voltage under typical office loads such as document editing, web browsing and video playback. Internal protection circuitry guards against over-charge, over-discharge and short-circuit events during extended sessions. No active cooling is required; the pack runs at ambient chassis temperature.

Direct swap for degraded factory units

Owners of the listed Lenovo series whose original packs no longer hold a useful charge can install this unit without tools beyond a standard screwdriver. The upgrade is worthwhile when run-time has fallen below two hours or the system throttles due to battery health warnings. It does not serve laptops outside the named model families or users needing higher capacity than 36 Wh.

Questions about this item

Does the 11.58V 3108mAh battery generate noticeable heat or noise during all-day use?

Lithium-ion batteries produce no audible noise. Under normal load the 36Wh pack runs cool; only heavy sustained charging may cause mild warmth.

Must my Lenovo laptop already have the L17M3P61 or 5B10N87357 part number for this replacement to fit?

Yes — it replaces L17M3P61, 5B10N87357, L17C3P61, 5B10N87359 and 81AK. Verify the original part number before ordering.

Will the 11.58V replacement work alongside the original charger and motherboard in a Yoga 720-12IKB?

The voltage and capacity match the factory specification, so the existing charger and motherboard recognise it normally.
