Compatible replacement battery

The Batianda L19D4PH3 is a 61Wh 4-cell lithium-ion battery built for Lenovo Yoga Slim 7 Pro and Slim 7 models including the 14ITL5, 14ARH5, 14IHU5, 14ACH5, 14IAP7 and 14IAH7 series. It replaces part numbers L19D4PH3, L19M4PH3, L19C4PH3, SB10Z49515, 5B10Z49514, SB10Z49516, 5B10Z49518, SB10Z49517 and 5B10Z49519. Buyers whose laptops use a different battery model or voltage should verify the original part before ordering.

Sustained capacity delivery

Rated at 15.44V and 3950mAh, the pack supplies its full 61Wh over a normal discharge cycle rather than only in short bursts. The four cells share the load evenly so voltage remains stable during extended work sessions, video playback or light compilation tasks. Capacity will gradually decline with age and charge cycles as is normal for lithium-ion chemistry.

Thermals and power draw

The battery operates at the laptop's designed 15.44V without additional converters, so heat generation stays within the chassis cooling envelope. No fan or active cooling is required on the battery itself. Power draw follows the system's demand profile; using the original charger ensures correct charge termination and cell balancing.

Questions about this item

How much heat or noise does the 15.44 V 61 Wh battery produce during all-day use?

The battery itself has no moving parts and generates no audible noise; any warmth felt comes from the laptop's own power draw during sustained workloads.

Which existing laptop model and original battery part number must I already own for this replacement to fit?

It replaces Lenovo part numbers L19D4PH3, SB10Z49515, 5B10Z49514, L19M4PH3, SB10Z49516, 5B10Z49518, L19C4PH3, SB10Z49517 and 5B10Z49519 in compatible Yoga Slim 7 Pro and Slim 7 series machines.

Will the 4-cell 3950 mAh pack work reliably alongside the original charger and motherboard in an older Yoga Slim 7 Pro?

Yes — install it with the connector firmly seated, charge with the original adapter, then cycle the new pack to 5 % and back 3–4 times to calibrate it with the existing hardware.
