Industrial power tool battery

The KingSener NI2040HD is a Li-Polymer replacement battery rated at 7200mAh and 10.8V. It is built for technicians who need a direct substitute for Inspired Energy NI2040 series packs in portable test instruments.

Thermals noise and power draw

Li-Polymer chemistry runs cooler than older nickel types and holds voltage steadily during the long measurement sessions typical of spectrum analysers and flaw detectors. No fan or active cooling is required inside the instrument.

Compatible part numbers and instruments

This pack replaces part numbers NI2040, NI2040HD, NI2040PH, NI2040XD, NI2040AG, NI2040ED, NI2040JD29, NI2040SL24 and LI204SX. It fits the Omniscan SX Phased Array Ultrasonic Flaw Detector and the Oscor Green 24G Spectrum Analyzer.

Not for users needing other voltages

Buyers whose equipment requires a different voltage or capacity cannot use this pack. Builders looking for a higher-capacity cell or a different form factor must source an alternative model.

Questions about this item

How do I install the NI2040HD battery into an Omniscan SX detector?

Power off the device, open the battery compartment, align the connector, insert the pack until it clicks, then close the latch. The step often missed is fully seating the connector before latching.

What maintenance will the 7200mAh Li-Polymer pack need later?

Store at roughly half charge if unused for weeks, avoid deep discharge, and keep contacts clean; the pack itself is sealed and requires no user servicing.

What limit appears first during continuous use of the 10.8V battery?

Runtime is limited by the 7200mAh capacity; sustained high-draw operation will deplete the charge before thermal limits are reached.
