About this replacement
Scanreco 590 / 960 Series — 7.2V Ni-MH Replacement Battery (RSC7220)
This is a 7.2V, 2000mAh Ni-MH replacement battery for Scanreco crane and hoist remote control systems. It fits the 590, 592, 960, and 790 series wireless pendant controls used in industrial lifting and material handling operations. OEM part numbers RSC7220, 13445, 16131, and 17162 all cross-reference to this cell configuration.
- 590 / 592 / 960 / 790 series compatibility: These remotes share the same battery bay dimensions, 7.2V nominal rail, and connector pinout. The BMS handshake on each model expects a Ni-MH cell stack — substituting Li-ion chemistry will cause the remote to reject the pack or misread state of charge.
- Bench tested on actual hardware: We cycled this pack through full charge and discharge on a 590-series remote. The BMS accepted the pack without error flags, solenoid activation held stable voltage, and the charge termination cut off cleanly at capacity.
- Monthly charge during idle periods: Crane remotes often sit unused between jobs or seasons. Ni-MH cells self-discharge at roughly 1–2% per day — a pack left dormant for two months can drop low enough that the charger detects no response. Charge the battery once a month during any idle period to keep cells above the recovery threshold.
Solenoid activation causing power dropout on a fresh battery
When the Scanreco remote triggers a crane solenoid or relay, the inrush current spike can exceed what a depleted or cold Ni-MH pack can sustain. The BMS trips the output to protect the cells, and the remote resets mid-operation. This is not a fault with the remote — it is a voltage sag response. A fully charged pack at room temperature handles these inrush events without tripping. If dropouts persist on a fully charged battery, check that the cell contacts in the battery bay are clean and seated flat.
Remote showing low-battery indicator immediately after installing a new pack
Replacement Ni-MH packs ship at storage voltage — typically 6.0–6.5V for a 7.2V pack — not at full charge. The Scanreco remote reads this as a low or critical battery state and flags it on startup. This is expected behaviour, not a defective cell. Connect the battery to the Scanreco charger and run a full charge cycle before placing the remote back in service. The indicator clears once the pack reaches its nominal 7.2V charge state.
