Scanreco RSC7220 Kranfunksteuerung 592 Compatible Battery 7.2V 3000mAh

Scanreco Kranfunksteuerung 592 Series — 7.2V Ni-MH Replacement Battery (RSC7220)

This is a 7.2V 3000mAh Ni-MH battery for the Scanreco Kranfunksteuerung 592 wireless crane remote control. It fits across the 590, 592, 790, and 960 series remotes used to operate overhead cranes and lifting equipment in industrial environments. Voltage and pack geometry match the original RSC7220 specification.

• 590 / 592 / 790 / 960 series compatibility: These remotes share the same 7.2V battery bay, connector pinout, and BMS handshake protocol. One pack covers the full range without modification or adapter wiring.
• Bench tested on actual hardware: We cycled this pack through load conditions that mirror solenoid activation spikes. The BMS held stable across repeated inrush draws without tripping into protection mode during our discharge cycles.
• Monthly charge during idle periods: Crane remotes often sit unused for weeks between jobs. Ni-MH cells lose charge through self-discharge at roughly 1–3% per day at room temperature. A monthly top-up prevents the cell voltage from dropping to a level that causes the remote to refuse power-on at the next job start.

Solenoid activation causing power dropout on the Scanreco 592 remote

When a crane solenoid or relay fires, it pulls a short inrush current that can spike several times the steady draw of the remote's transmitter circuit. A degraded or partially discharged battery sags under that load, dropping voltage below the BMS cutoff threshold. The result is a momentary dropout — the remote resets or goes dark exactly when a lift command is sent. A fresh, fully charged 3000mAh pack provides enough current headroom to absorb the inrush without the voltage rail collapsing below 6V.

Ni-MH cells ship at storage voltage — typically 1.1–1.15V per cell, which puts a 6-cell 7.2V pack at roughly 6.6–6.9V. The Scanreco remote's low-battery threshold sits above storage voltage, so the indicator triggers even with a brand-new pack installed. This is not a fault with the battery. Plug the pack into the Scanreco charger and run a full charge cycle before first use — the indicator clears once cell voltage reaches the normal operating range above 7.0V.
