Compatible Replacement for Efficia DFM100

The KingSener 989803190371 is a lithium-ion battery built to match the original 4ICR19/66-2 M6482 pack used in Efficia DFM100 and DFM-100 medical devices. It delivers the same 14.8 V output and 5000 mAh capacity in a black housing that fits the original compartment without modification.

5000 mAh Capacity and 14.8 V Output

Rated at 5000 mAh and 14.8 V, the pack supplies the design capacity in full with no inflated figures. High-quality cells and PCB provide stable voltage through the discharge cycle, giving extended run time for monitoring sessions; capacity will diminish only after repeated deep cycles or exposure to heat and humidity.

Direct Swap for OEM 989503190371

This unit replaces the original 989503190371 battery with identical dimensions and connector layout, so installation requires no adapters or case changes. The upgrade is worthwhile when the original pack no longer holds a charge or when a spare is needed for continuous operation; it is not suited for devices that require a different voltage or form factor.

Questions about this item

Will this 14.8 V 5000 mAh Li-ion battery fit the original slot in my Efficia DFM100 without modification?

Yes, it is built to the same dimensions as the original 989803190371 pack, so it installs directly into the DFM100 or DFM-100 battery compartment.

How can I confirm the pack is delivering its rated capacity after the first few charge cycles?

Fully charge and discharge it from low current two or three times; the runtime should then match or exceed the 5000 mAh design capacity.

Does the package include a charger or only the 4ICR19/66-2 cell pack itself?

Only the replacement battery is supplied; a compatible charger for the 14.8 V Li-ion pack must be purchased separately.
