Falard 20xN3000-FAL Crane Remote Replacement Battery 12V

Falard LEM 460 / PEM 807 Geismar — 12V Ni-MH Replacement Battery (20xN3000-FAL)

This is a 12V, 3000mAh Ni-MH replacement battery for the Falard remote control unit used with Geismar LEM 460 Self-Propelled Transport Trolleys, PEM 807 Self-Propelled Gantries, and associated Surrogate Radio systems. It matches OEM part number 20xN3000-FAL. Voltage, capacity, and connector position match the original Falard remote specification.

• LEM 460, PEM 807, and Surrogate Radio compatibility: All three platforms share the same Falard remote control housing and 12V Ni-MH power rail. The BMS handshake and cell count are identical across the series, so one battery covers all three units without modification.
• Bench tested on actual hardware: We ran this cell pack through charge and load cycles on a Falard remote test rig. The BMS held stable under solenoid activation inrush and did not trip during trolley movement commands at full travel speed.
• Ni-MH storage protocol for infrequently used remotes: Geismar transport systems often sit idle between track maintenance windows. Ni-MH cells lose roughly 20–30% charge per month at room temperature. If the remote is stored for more than three weeks, top up the charge before returning it to service — cells discharged below the BMS floor voltage will cause the remote to appear dead on power-up.

Solenoid activation causing power dropout mid-command on the LEM 460 remote

When the LEM 460 trolley receives a directional command, the remote fires a solenoid relay that draws a sharp inrush current spike lasting 20–80 milliseconds. An aged or partially discharged Ni-MH pack cannot sustain voltage during this spike, and the BMS cuts the output to protect the cells. The remote goes dark mid-transmission, and the trolley stops receiving signals. A fully charged 3000mAh pack at 12V nominal handles this inrush without a voltage sag large enough to trigger cutoff — always ensure the battery reads above 12.5V before starting a trolley movement sequence.

Remote showing low-battery warning immediately after fitting a new cell pack

Replacement Ni-MH batteries ship at storage voltage — typically 10.8–11.4V for a 12V pack — not at full charge. The Falard remote's voltage monitor reads this as a low-battery state and flags the warning within seconds of power-up. This is not a faulty battery. Connect the pack to the Geismar-specified charger and run a full charge cycle before first use. Once the pack reaches 13.2–13.8V at end of charge, the warning will clear and the remote will operate normally.
