Direct replacement for Lenovo Yoga 3 14

This KingSener L14S4P72 battery is built for owners of the Lenovo Yoga 3 14, Yoga 700 14ISK, Yoga3 14-IFI and Yoga3 14-ISE models. It matches the original L14M4P72, 5B10K10224 and related part numbers exactly. The 7.4 V lithium-ion pack delivers 45 Wh and 6230 mAh in the same physical footprint as the factory unit. No modifications or adapters are required for installation.

Brand-new cells and protection circuit restore

The pack uses new Li-ion cells and a fresh protection board, so the usable capacity meets the 45 Wh design rating without the shortfall common in aged originals. Stable output voltage supports consistent performance through the discharge cycle. The supplier advises two or three full charge and discharge cycles at low current to condition the cells, and warns against leaving the AC adapter connected continuously while the battery is fitted.

45 Wh capacity suits typical mobile workloads

At 45 Wh the battery provides enough energy for several hours of document editing, web browsing or video playback on the target ultraportables. Heavy multi-tasking, sustained high brightness or demanding applications will deplete the charge more quickly. The 80 % storage guideline means the pack should be topped up at least once a month if the laptop is shelved for an extended period.

Questions about this item

Does the 45WH 7.4V Li-ion pack need any periodic recalibration to keep its reported capacity accurate?

Yes. Fully charge and discharge it from low current two or three times when new, then repeat once a month if the battery is removed for long periods.

What is the first limit reached during continuous discharge — the 6230mAh capacity or the 7.4V voltage floor?

The 6230mAh capacity is the hard limit; once those milliampere-hours are spent the voltage drops below the usable 7.4V threshold and the laptop shuts down.

How much heat does the battery generate when the Yoga 3 14 or Yoga 700 14ISK runs all day on mains power?

The supplier warns against leaving the adapter connected for long periods while using the battery, as sustained trickle-charge heat can damage the cells.
