Replacement Battery for Ultrasonic Flaw Detectors

This lithium-ion pack is built for the RRC2040 ultrasonic flaw detector industrial controller. It delivers 10.8V and 36.2Wh capacity in a black housing. Technicians servicing field inspection equipment will find it matches the original form factor. The unit ships new and ready for immediate deployment.

Voltage and Capacity Match the Original

The critical figure is the 10.8V output combined with a 36.2Wh energy rating, equivalent to 3350mAh. If your device requires a different voltage or a significantly higher capacity, this battery will not power it correctly. Always verify the controller's nameplate before ordering to avoid a mismatch.

Direct Swap With No Soldering Required

Installation consists of opening the controller's battery compartment and sliding the pack into place. The connector aligns with the original socket, so no tools or wiring changes are needed. A common error is forcing the connector when the orientation is reversed; check the keying groove before applying pressure.
