HBC BA223000 Radiomatic Quadrix Crane Remote Replacement Battery 3.6V 2000mAh Ni-MH

HBC Radiomatic Quadrix Series — 3.6V Ni-MH Replacement Battery (BA223000)

This is a 3.6V, 2000mAh Ni-MH replacement battery for HBC Radiomatic industrial crane remote controls. It fits the Radiomatic Quadrix, Keynote, Patrol D, Micron 4, and several additional HBC Radiomatic handsets that share the BA223000 cell format. The battery slots into the remote's rear compartment and restores wireless control of overhead cranes and hoists.

• Shared platform — Radiomatic series: HBC built the Radiomatic line around a common 3.6V single-cell Ni-MH format. The BA223000, BA223030, and FUB6 part numbers reference the same physical cell and connector, so one battery covers the full Radiomatic platform without rewiring or adapters.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Radiomatic-class remote. The BMS accepted a full charge without flagging cell mismatch, and the remote transmitted control signals without voltage dropout during simulated crane operation.
• Monthly charge during idle periods: Crane remotes often sit unused for weeks between jobs. Ni-MH cells left in a discharged state below 1.0V per cell can develop voltage depression — a condition where the cell accepts charge but delivers reduced capacity. A short charge once a month prevents this.

Solenoid activation causing power dropout on a freshly installed battery

When a crane solenoid or relay fires, it draws a short burst of current that can exceed what a partially charged or low-capacity cell delivers cleanly. The remote's BMS reads this as an undervoltage event and cuts power to protect the cell. This shows up as the remote going dark or resetting mid-operation, even though the battery is new. Charge the battery fully before the first use — a storage-voltage cell sitting at around 1.1V per cell will trip the BMS under inrush load before it ever reaches the crane controller.

Remote showing "low battery" immediately after fitting a new cell

New Ni-MH cells ship at storage voltage — typically 1.1–1.2V per cell — not at full charge. The Radiomatic remote reads this as a depleted battery and flags the warning straight away. This is not a faulty cell. Place the remote on its charger for a full charge cycle before use. Once the cell reaches its nominal 1.2V per cell under load, the low-battery indicator will clear and the remote will operate normally.
