Purpose-built replacement

This lithium-ion cell delivers 7.2V and 3350mAh for the Inspired Energy NF2037HD flaw detector. It matches the original 24.12Wh rating and uses part numbers RRC2037 and 21NR19/66 for direct compatibility. The black housing fits the instrument without modification.

Suits field technicians

Engineers who need a fresh power source for an existing NF2037HD unit will find this cell restores full runtime. It is not for users of other flaw detector models or for anyone requiring a different voltage or chemistry. Buyers without this specific instrument should look elsewhere.

Simple swap-in

The battery installs by opening the detector's compartment and inserting the pack; no tools or soldering are required. Alignment of the connector is the only step that can go wrong, so verify orientation before pressing home. The package includes one cell.

Questions about this item

Does the RRC2037 battery require a specific charger for the Inspired Energy NF2037HD Flaw Detector?

The 7.2V 3350mAh Li-ion pack is designed as a direct replacement for the NF2037HD detector, so it charges inside the instrument using its original charging circuit.

Will the RRC2037 fit the same battery compartment as the original 21NR19/66 part in my NF2037HD detector?

Yes, the RRC2037 matches the 21NR19/66 form factor and 7.2V specification, allowing it to seat correctly in the existing NF2037HD battery bay.

How can I confirm the RRC2037 is delivering its rated 24.12Wh capacity after installation?

Run a full charge-discharge cycle on the NF2037HD and verify the detector reports approximately 3350mAh or 24.12Wh of usable capacity.
