About this replacement
HBC FUB9NM Crane Remote — 6V Ni-MH Replacement Battery (BA209060)
This is a 6V 700mAh Ni-MH replacement battery for the HBC FUB9NM wireless radio remote transmitter. It fits the FUB9NM and FBFUB09N series crane remote controls used to operate overhead cranes and lifting equipment in industrial environments. Voltage and capacity match the original BA209060 specification exactly.
- FUB9NM and FBFUB09N compatibility: Both models share the same 6V battery bay, connector pinout, and charge management circuit. The BA209060 and BA209061 part numbers are interchangeable across this platform — HBC revised the part number without changing the cell specification or form factor.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on FUB9NM hardware. The BMS accepted charge from the standard HBC dock without fault codes, and the transmitter held a stable 6V rail through repeated solenoid-activation sequences.
- Storage charge for infrequently used remotes: HBC crane remotes often sit unused for weeks between shifts. Charge this battery once a month during idle periods. Ni-MH cells discharged below the BMS low-voltage threshold through self-discharge may not recover on a standard dock — a full discharge recovery can take two to three charge cycles.
Solenoid activation causing power dropout on a freshly installed battery
When the FUB9NM transmits a crane command, the solenoid or relay in the receiving unit draws a short inrush current. If the replacement cell is at storage voltage rather than a full charge, internal resistance is higher than normal. That elevated resistance causes a voltage sag at the moment of activation. The transmitter's BMS interprets this sag as a low-cell event and cuts output — the remote appears to lose power mid-command.
Remote showing low battery immediately after cell swap
A freshly unpacked Ni-MH cell ships at storage voltage — typically around 5.4–5.6V on a 6V pack — not at full charge. The FUB9NM reads this as a low-battery condition and flags it on the indicator. This is not a fault with the cell. Connect the remote to the HBC charging dock and run a full charge cycle before first use. The low-battery warning should clear once the pack reaches 6.0–6.3V.
