About this replacement
HBC Radiomatic Eco / Linus 6 / Technos — 6V Ni-MH Replacement Battery (BA225000)
This is a 6V 2000mAh Ni-MH battery for HBC Radiomatic crane and hoist remote controls. It fits the Radiomatic Eco, Linus 6, Technos, and Spectrum A series. It replaces OEM part numbers BA225000, BA205000, BA206000, BA225030, and several FuB-series codes.
- Radiomatic platform fit: The Eco, Linus 6, Technos, and Spectrum A share the same 6V cell architecture, connector pinout, and physical housing dimensions — 82.30 x 56.90 x 24.40mm. One cell swap covers all four platforms without modification.
- Bench tested on actual hardware: We cycled this cell through solenoid-activation loads on the Radiomatic Eco. The BMS held stable across repeated relay inrush events without tripping cutoff or registering false low-battery flags.
- Monthly charge during idle storage: Crane remotes often sit unused between projects for weeks or months. Ni-MH cells self-discharge at roughly 20–30% per month at room temperature. Charge the battery once a month during downtime — cells discharged below their recovery threshold will not respond to a standard charger cycle.
Solenoid activation causing power dropout on a freshly installed battery
When a crane solenoid or relay energises, it draws a sharp inrush current that can spike two to three times the steady-state load. If the battery is at partial charge, its internal resistance is higher and terminal voltage dips sharply during that spike. Some Radiomatic BMS boards interpret this dip as a depleted cell and cut output. Charge the replacement battery fully before the first operational use — a battery at storage voltage will not handle inrush loads the same way a fully charged cell will.
Remote shows low battery immediately after new cell is installed
A fresh Ni-MH cell ships at storage voltage — typically 5.4–5.6V on a 6V pack. The Radiomatic firmware reads this as low and flags it before the battery has been conditioned. This is not a defective cell. Connect the battery to its charger for a full charge cycle before powering on the remote. After one full charge the voltage should read at or above 6.0V and the low-battery indicator will clear.
