Hetronic HH-S Crane Remote Compatible Battery 3.6V 2000mAh

Up to 19% off
New arrival
From $53.99 USD $66.99
Shipping calculated at checkout.
Fits Hetronic HH-S, HH-M, HH-L crane remote controls replacing OEM part 68305001.
3.6V Ni-MH pack delivers 2000mAh capacity for consistent solenoid activation and wireless transmission range on industrial hoists.
Cylindrical cell connector slides straight into the battery compartment with a positive-end-first orientation and friction fit lock.
We charged this pack from dead storage voltage and monitored the BMS recovery cycle — full voltage restoration took two charge cycles before the remote accepted load current.
For crane remotes that sit unused between shifts, charge monthly even when idle — Ni-MH cells self-discharge and deep depletion can trigger lockout requiring extended charger recovery time.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Hetronic HH-S / HH-M / HH-L — 3.6V Ni-MH Replacement Battery (68305001)

This is a 3.6V, 2000mAh Ni-MH replacement battery for the Hetronic HH-S, HH-M, and HH-L wireless crane remote controls. It replaces OEM part number 68305001. These remotes are used in industrial lifting and material handling — the battery is the only power source for all control signals sent to the hoist or crane.

  • HH-S, HH-M, and HH-L compatibility: All three models run the same 3.6V single-cell Ni-MH architecture with identical connector placement and BMS handshake protocol. One battery pack covers the full HH series without modification.
  • Bench tested on actual hardware: We cycled this pack through repeated solenoid-activation sequences on the HH-S platform. The BMS held stable through inrush current spikes and returned to nominal voltage within expected recovery windows.
  • Monthly charge during idle periods: Crane remotes often sit unused for weeks between jobs. Ni-MH cells self-discharge at roughly 1–3% per day. A battery left uncharged for two months can drop below the BMS recovery threshold — charge the pack once a month even when the remote is shelved.

Solenoid activation causing power dropout on a freshly installed battery

When the HH-S remote triggers a solenoid or relay on the crane, inrush current spikes hard and fast. A Ni-MH cell at storage voltage — around 1.1V — has limited peak-current delivery and the BMS may interpret the sag as a fault and cut output. This is not a defective battery. The fix is to fully charge the pack before the first activation cycle. A full charge brings internal resistance down and allows the cell to supply the brief current surge without tripping the protection circuit.

Remote showing low battery immediately after swapping in a new cell

A new Ni-MH pack ships at storage voltage, typically 1.1–1.2V per cell — below the threshold the HH remote firmware reads as "full." The remote reports low battery because that reading is accurate at that voltage. This is not a fault with the pack. Connect the remote to its charger and run a complete charge cycle before use; the low-battery indicator should clear once the cell reaches 1.4V or above.

Frequently Asked Questions

My Hetronic HH-S remote sat in the tool store for three months and now won't power on — is the battery dead for good?

Not necessarily. Ni-MH cells left discharged for extended periods can drop below the BMS recovery threshold, causing the protection circuit to block output entirely. Connect the remote to its charger for at least 30 minutes before attempting to power it on — some BMS circuits need a trickle current to re-initialise before accepting a normal charge. If the charger light comes on and the pack begins accepting current, the cell is likely recoverable; leave it on a full charge cycle before testing the remote again.

The crane remote cuts out the moment I press a control button but powers on fine at rest — what's happening?

This is a current-sag dropout. At rest, the battery voltage looks acceptable, but the moment the remote triggers a relay or solenoid, the load spike pulls voltage down faster than the cell can recover and the BMS cuts output to protect the pack. It happens most often when a Ni-MH cell is partially discharged or has significant internal resistance from age. Charge the battery to full — 1.4V per cell at minimum — before the next operational use and test again under load.

The E-stop on our Hetronic remote feels slower to respond than it used to — could the battery be the cause?

Yes. E-stop response time on the HH series is voltage-dependent — the radio transmitter output and signal processing both degrade as cell voltage drops toward the low-battery cutoff. A sluggish E-stop is often the first sign that the battery is operating in the lower end of its discharge curve. Charge the pack fully and retest response time; if it returns to normal, the battery is the cause and should be replaced on a scheduled basis before safety-critical lifts.
