Scanreco RSC7220 Replacement Battery 7.2V 2000mAh Ni-MH

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

This 7.2V 2000mAh Ni-MH battery replaces the RSC7220 cell pack in Scanreco wireless crane remote control systems. It fits the Kranfunksteuerung 590, 592, 790, and 960 series remotes used to operate industrial hoists and overhead cranes on job sites. Voltage and capacity match OEM spec exactly — no modifications needed to seat or connect the pack.

• Kranfunksteuerung 590 / 592 / 790 / 960 platform compatibility: These remotes share the same 7.2V battery bay, connector pinout, and BMS handshake protocol across the range. A single cell pack services all four variants without adapter or firmware intervention.
• Bench tested on actual hardware: We ran this pack through full charge-discharge cycles on a Scanreco remote test rig. The BMS accepted the cell chemistry without fault codes, and the solenoid activation channels held voltage through repeated relay-trigger events without dropout.
• Monthly charge during crane downtime: Crane remotes often sit unused for weeks between projects. Ni-MH cells self-discharge at roughly 20–30% per month — if the pack drops too low, the remote's protection circuit will refuse to accept a charge. Connect the remote to its dock once a month during idle periods to keep cells above the cutoff threshold.

Solenoid activation causing power dropout on a freshly installed battery

When a crane remote triggers a solenoid or relay, the inrush current spikes sharply for the first few milliseconds. If the battery is at storage voltage rather than full charge, internal resistance is higher and the BMS may read that spike as an overcurrent event and cut the output rail. The remote then shuts off mid-command — a dangerous outcome on a live lift. A full charge before first use lowers internal resistance enough that the BMS tolerates the inrush without tripping. Charge the pack completely before putting it into service; resting voltage at full charge for this 7.2V Ni-MH pack should read approximately 8.4–8.6V off the charger.

Remote showing low-battery warning immediately after new cell install

Ni-MH cells ship at storage voltage — typically 60–70% state of charge — not at full capacity. The Scanreco remote reads cell voltage on boot and will flag low battery if it sees anything below its threshold, even with a brand-new pack installed. This is not a fault with the battery. Connect the remote to the OEM dock charger and run a full charge cycle before use. Once complete, the low-battery indicator should clear and the remote will report normal status.
