HBC BA301031 Crane Remote Replacement Battery 3.7V 1800mAh

HBC Orbit TC240 — 3.7V Li-ion Replacement Battery (BA301031)

This is a 3.7V, 1800mAh Li-ion replacement battery for the HBC Orbit TC240 crane remote control transmitter. It replaces OEM part numbers BA301031 and BA301030. The Orbit TC240 is a handheld wireless transmitter used to operate overhead cranes and hoists in warehouses and manufacturing facilities.

• Orbit TC240 transmitter fit: The TC240 runs on a single-cell 3.7V Li-ion pack with a compact 52.80 × 56.00 × 14.30mm footprint. The BMS in this replacement matches the voltage thresholds and connector pinout the TC240's internal charging circuit expects — no handshake mismatch, no false low-battery flags.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the TC240 platform. The BMS held cutoff correctly at low-voltage thresholds, and the transmitter registered a clean full-charge state without any fault codes.
• Monthly charge during idle periods: Crane remotes often sit unused for weeks between jobs. Li-ion cells left discharged below 2.5V enter deep-discharge BMS lockout — the transmitter will show no response even with a charger connected. Charge this battery at least once a month during any extended idle period to keep the cell above that threshold.

Why the TC240 transmitter drops out when activating a solenoid or relay

Solenoid and relay activation on a crane circuit creates a brief inrush current spike that gets fed back through the transmitter's power rail. If the battery's BMS interprets that spike as an overcurrent event, it trips and cuts output — the transmitter goes dark mid-operation. A battery at partial state of charge has less voltage headroom to absorb that transient, making dropout more likely. Always start solenoid operations with a fully charged cell at or above 4.1V to keep the BMS in its stable operating window.

Replacement Li-ion cells ship at storage voltage — typically around 3.6–3.8V — not at full charge. The TC240's firmware reads this as a low-battery condition and flags it straight away. This is not a fault with the battery. Connect the transmitter to its charger and bring the cell to a full 4.2V before putting it into service. The low-battery indicator will clear once the cell reaches its correct charged state.
