About this replacement
HBC Patrol S / Radiomatic RV — 2.4V Ni-MH Replacement Battery (BA202060)
This is a 2.4V, 2000mAh Ni-MH replacement for the HBC BA202060 battery cell. It fits the HBC Patrol S and Radiomatic RV wireless crane remote controls. These remotes operate overhead cranes and industrial lifting equipment, so a dead battery mid-shift means a stopped crane.
- Patrol S and Radiomatic RV compatibility: Both remotes use the same 2.4V two-cell Ni-MH pack with the BA202060 form factor. The voltage rail, connector, and physical dimensions are identical across both units — one battery covers both platforms.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench, confirming stable output through the transmitter's full signal-load draw. The cell held capacity across repeated cycles without voltage sag dropping the remote offline.
- Infrequent-use charging schedule: Ni-MH cells in crane remotes sitting in a locker for weeks will self-discharge below safe operating voltage. Charge the battery once a month during idle periods — cells left fully discharged for extended time can lose the ability to accept a full charge and will show low battery immediately after install.
Why the Patrol S remote cuts out during solenoid or relay activation
When the crane's receiver triggers a solenoid or contactor, there is a brief inrush current spike back-reflected through the RF link. A battery cell near end-of-life cannot hold its voltage rail through that spike, causing the transmitter to momentarily dropout or reset. This looks like a radio fault but is a battery voltage issue. A fresh, fully charged BA202060 at 2.4V handles the transient without the remote losing power.
Remote shows low battery immediately after fitting a new cell
New Ni-MH cells ship at storage voltage — typically 1.0–1.1V per cell, putting a two-cell pack around 2.0–2.2V total. The Patrol S interprets anything below its low-battery threshold as a depleted pack, so the indicator triggers straight away. This is not a faulty battery. Connect the remote to its charger for a full charge cycle before use — once the pack reaches 2.4V under load, the low-battery warning will clear.
