About this replacement
Scanreco 590 / 960 Series — 7.2V Ni-MH Replacement Battery (RSC7220)
This is a 7.2V 3000mAh Ni-MH battery for Scanreco wireless crane remote controls. It fits the 590, 592, 960, and 790 series transmitters used to operate overhead and gantry cranes. Voltage and capacity match the OEM spec exactly — RSC7220 / 13445 / 16131 / 17162.
- 590, 592, 960, and 790 compatibility: These models share the same 7.2V battery rail, connector pinout, and charge management circuit. One cell format covers the full range — no adapter or wiring change needed.
- Bench tested on actual hardware: We cycled this cell through the Scanreco charge dock and monitored BMS handshake through full charge and discharge. The protection circuit held cutoff at the correct thresholds across all test runs.
- Ni-MH storage protocol for infrequently used crane remotes: If the remote sits unused for weeks, charge the battery once a month. Ni-MH cells left discharged for extended periods develop voltage depression — the charger may read "full" after a short cycle but actual usable capacity drops significantly. A full conditioning charge corrects this before returning the remote to service.
Solenoid activation causing power dropout on a freshly installed battery
When the remote triggers a crane solenoid or contactor relay, the inrush current spike can trip the battery's BMS if the cell hasn't reached full charge voltage. A Ni-MH cell at storage voltage — typically around 6.0–6.4V — has less headroom to absorb that surge. The BMS interprets the sudden load as an overcurrent event and cuts output. Charge the battery fully before first operational use; a rested, fully charged 7.2V Ni-MH cell handles inrush without triggering cutoff.
Remote showing "low battery" immediately after swapping in a new cell
A new Ni-MH battery ships at storage voltage, not full charge — typically 60–70% of rated capacity. The Scanreco remote reads cell voltage on startup, and a reading below its internal threshold triggers the low-battery indicator right away. This is not a fault with the battery. Connect it to the Scanreco charger and run a complete charge cycle until the charger indicates termination. After a full charge, the resting voltage should sit at or above 7.2V and the low-battery warning will clear.
