Arcon E-pack S Crane Remote Ni-MH Compatible Battery 3.6V 2000mAh

Arcon E-pack S — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 2000mAh Ni-MH replacement battery for the Arcon E-pack S crane remote control. It fits the handheld transmitter unit used to operate overhead cranes and hoists in industrial environments. Swap it in when the original cell can no longer hold a working charge.

• E-pack S transmitter fit: The E-pack S uses a 3.6V Ni-MH cell pack at this specific form factor — 60.20 x 54.55 x 22.20mm. The transmitter's internal regulator and charge circuit are matched to Ni-MH chemistry, so the voltage profile during charge and discharge aligns correctly with what the remote expects.
• Bench tested on actual hardware: We cycled this cell through repeated solenoid-activation sequences on the bench. The battery held voltage above the remote's cutoff threshold across sustained button-press loads, and the charge circuit terminated correctly at full capacity.
• Crane remote storage charging: If the E-pack S remote sits unused for more than four weeks, connect it to the charger for a full cycle before returning it to service. Ni-MH cells in low-drain standby devices lose capacity through self-discharge, and the remote may signal low battery immediately on power-on if the cell has drifted too far down.

Power dropout during solenoid or relay activation on the E-pack S

When you press a crane direction button, the remote fires a solenoid command through the receiver — that activation draws a short inrush current spike. A degraded or partially discharged Ni-MH cell can sag enough under that spike to drop the transmitter voltage below its operating floor. The remote resets or cuts out for a moment, even though it appeared charged. A fully charged, capacity-rated cell handles the inrush without voltage sag that trips the cutoff.

Replacement Ni-MH cells ship at storage voltage — typically around 1.0–1.1V per cell, which puts a 3.6V three-cell pack well below operating level. The E-pack S reads this as low battery the moment you power on. This is not a fault with the battery or the remote. Charge the battery fully in the remote's cradle or external charger before first use, and the low-battery indication will clear once cells reach their nominal 1.2V per cell.
