Autec LK NEO Crane Remote Replacement Battery 3.6V 500mAh

Autec LK NEO — 3.6V Ni-MH Replacement Battery (MHM03)

This is a 3.6V, 500mAh Ni-MH replacement battery for the Autec LK NEO wireless crane remote control. It matches OEM part numbers MHM03 and R0BATT00E11A0. The LK NEO is an industrial hoist and crane remote — keeping its battery in good condition directly affects safe lifting operations.

• LK NEO platform fit: The LK NEO uses a single-cell Ni-MH pack at 3.6V nominal. This voltage rail matches the radio transmitter circuit and the internal BMS handshake. Swapping to a different voltage or chemistry risks locking out the remote's control board entirely.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a controlled bench rig. The BMS accepted the cell without fault codes, and charge acceptance held steady across multiple cycles at the rated 500mAh.
• Storage protocol for infrequently used crane remotes: If the LK NEO sits unused for weeks, charge the battery once a month. Ni-MH cells self-discharge faster than Li-ion — a deeply discharged Ni-MH can reverse-polarise under load, which the remote's internal circuitry will not recover from without a conditioning charge cycle.

Solenoid activation causing power dropout on a freshly installed battery

When the LK NEO triggers a crane solenoid or relay, it draws a short inrush current spike. A partially discharged or aged Ni-MH cell cannot sustain voltage through that spike, and the remote drops out momentarily. This looks like a transmission fault but is actually a voltage sag event at the cell level. A fully charged, capacity-rated cell at 500mAh handles the inrush without dropping below the remote's minimum operating voltage threshold.

Remote showing low battery immediately after new cell install

Ni-MH cells ship at storage voltage — typically 1.1–1.15V per cell, which reads as low on the LK NEO's internal fuel gauge. This is not a faulty battery. Connect the remote to its charger before first use and run a full charge cycle. Once the cell reaches a resting voltage of approximately 1.2V, the low-battery indicator will clear and the remote will operate normally.
