Industrial and medical replacement

This 7.2 V lithium-ion pack replaces part numbers RRC2130 and 21CP6/60/80 in flaw detectors and similar equipment. It is built for technicians and integrators who need a direct-fit power source for industrial or medical devices.

Voltage and capacity envelope

The cell chemistry fixes the nominal voltage at 7.2 V and the energy rating at 29.1 Wh or 4040 mAh, so run-time and charge parameters are determined by the host instrument. No higher-capacity version is offered in this form factor.

Single-match compatibility

The battery fits only units designed for the RRC2130 or 21CP6/60/80 footprint; it will not work in consumer laptops, tablets or other portable electronics that use a different connector or voltage.

Questions about this item

Which capacity should I choose for the RRC2130 battery?

The RRC2130 is offered as a single 29.1Wh 4040mAh lithium-ion cell at 7.2V, so there is only one capacity to select.

What does the 29.1Wh rating mean when the battery is installed in my device?

It indicates the total energy the pack can store; a device drawing 7.2W would run for roughly four hours on a full charge.

What interface does the 21CP6/60/80 pack use and what does it limit?

The pack connects via its proprietary RRC2130 connector, which limits use to equipment designed for that specific industrial or medical interface.
