Hetronic Ergo 9.6V Ni-MH Crane Remote Compatible Battery

Up to 20% off
New arrival
From $34.99 USD $43.99
Shipping calculated at checkout.
Fits Hetronic Ergo remote control models HE520, RHE9608KY, HT-02, 68300510, 68300520, and 68300525.
9.6V Ni-MH pack delivers 600mAh — adequate for solenoid actuation and wireless transmission on overhead crane remotes without voltage sag.
Connector slots into the Ergo battery cavity with a single locking tab; orientation keyed to prevent reverse installation.
We bench tested this cell against the Ergo solenoid load profile; BMS accepted the charge and delivered stable voltage under full button press cycles.
On first install after storage, charge the pack for 45 minutes before operating the E-stop or hoist functions — Ni-MH cells hold storage voltage lower than fresh discharge, and remote safety response depends on full nominal voltage.

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 Ergo Series — 9.6V Ni-MH Replacement Battery (HE520 / 68300520)

This is a 9.6V, 600mAh Ni-MH replacement battery for the Hetronic Ergo wireless crane remote control. It fits the Ergo platform and compatible models including 68300510, 68300520, and 68300525. Direct swap for the original cell pack — same voltage, same footprint at 65 × 60 × 22mm.

  • Ergo platform compatibility: The Ergo remote family shares a common 9.6V battery bay and connector pinout across the 68300510, 68300520, and 68300525 variants. The BMS in these remotes reads cell voltage on startup — any pack outside the 8.4–10.2V window will prevent the remote from transmitting.
  • Bench tested on actual hardware: We cycled this pack through full charge and discharge on the Ergo platform. The BMS accepted the pack cleanly, charge termination triggered correctly via delta-V detection, and the remote reached full operational status without fault codes.
  • Storage and idle charging for crane remotes: Crane remotes often sit unused between jobs. Ni-MH cells self-discharge at roughly 1–3% per day at room temperature. If this remote will be idle for more than two weeks, top up the charge beforehand — a partially discharged Ni-MH pack left for months can drop below the BMS acceptance threshold and refuse to charge normally.

Why the Ergo remote cuts out during solenoid or relay activation

When the Ergo remote triggers a crane solenoid or contactor, the radio module draws a short inrush current spike on top of normal transmit current. A degraded or partially charged pack can't sustain voltage through that spike, causing the remote's processor to brownout and drop the transmission. This shows up as intermittent command loss — the operator presses a button and the crane doesn't respond, but the remote appears powered. A fully charged, capacity-correct pack eliminates this: the 9.6V pack should read 10.0–10.2V at full charge before entering a control session.

New battery installed but remote shows low battery immediately

Ni-MH cells ship at storage voltage — typically 1.0–1.1V per cell, which puts a 8-cell 9.6V pack around 8.0–8.8V out of the box. The Ergo remote's charge indicator reads this as a depleted pack, not a fault. The fix is straightforward: connect the remote to its charger for a full cycle before use. After a complete charge the pack voltage will read 10.0V or above and the low-battery indicator will clear.

Frequently Asked Questions

My Hetronic Ergo remote won't turn on at all after sitting in the van for three months — is the battery dead?

Most likely the Ni-MH pack has self-discharged below the BMS acceptance threshold from prolonged storage. Connect the remote to its charger and leave it for at least 30–45 minutes before attempting to power on — the charger needs enough voltage present to begin the charge cycle. If the remote still won't power on after a full charge, the original pack has failed and needs replacing. A freshly installed replacement pack should read above 8.5V before the charger is connected; if it reads lower, the cells are already compromised.

The crane moves fine on light commands but drops out when I activate the hoist at full load — what's causing that?

Full-load hoist commands fire the contactor solenoid, which pulls significant inrush current through the remote's radio and relay circuit simultaneously. If the battery pack can't hold voltage through that spike — common in aged or partially charged Ni-MH cells — the remote processor browns out and the command is lost. Confirm the pack is fully charged before any load-critical operation; a healthy 9.6V Ni-MH pack should hold above 9.0V under transmit load. Replacing a degraded pack with a correct 600mAh cell resolves this dropout pattern.

The E-stop on my Hetronic Ergo feels sluggish — there's a noticeable lag before the crane responds. Could the battery be causing that?

E-stop response time is partly voltage-dependent: the remote's radio transmit power drops as cell voltage sags, which can increase the number of retries the receiver needs before confirming the stop command. A Ni-MH pack that reads below 8.8V under load is delivering degraded transmit output. Charge the pack fully and retest — a fully charged pack at 10.0–10.2V restores full transmit strength. If lag persists on a fresh full charge, check the charger's delta-V termination to confirm the pack is actually reaching peak charge and not cutting off early.
