Battery Care Tips
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
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-S — 3.7V Li-ion Replacement Battery (68303700)
This is a 3.7V, 2600mAh Li-ion cell that replaces OEM part 68303700 in the Hetronic ERGO-S wireless crane remote control. It fits the ERGO-S transmitter used in industrial crane, hoist, and material handling applications. Match the OEM part number before ordering — Hetronic makes several transmitter platforms with different cell formats.
- ERGO-S transmitter fit: The ERGO-S uses a single-cell 3.7V Li-ion pack with a specific BMS handshake and connector orientation. This cell matches the voltage rail and physical footprint of the original 68303700. Other Hetronic platforms such as the NOVA or MINI use different cell configurations and are not interchangeable.
- Bench tested on actual hardware: We cycled this cell through repeated solenoid-activation sequences, which draw brief inrush current spikes. The BMS held without false cutoff across all test cycles. Voltage at full charge measured consistently at 4.18–4.20V before load.
- Storage charge on idle remotes: Crane remotes often sit unused between jobs or seasonal shutdowns. If the ERGO-S will be inactive for more than three to four weeks, charge the battery first. Li-ion cells left below 2.5V for extended periods can trigger BMS lockout that a standard charger will not recover.
Solenoid activation causing power dropout on a new battery
When a crane remote triggers a solenoid or relay contactor, the current draw spikes sharply for 20–50 milliseconds. If the battery cell is at storage voltage rather than full charge, internal resistance is higher and voltage sags enough for the BMS to trip the output. This looks identical to a faulty battery but is a charge-state issue. Charge the cell fully to 4.2V before putting it into service — do not install and immediately operate.
Remote showing low battery immediately after fitting a new cell
Li-ion cells ship at 30–50% state of charge for transport safety compliance. The ERGO-S firmware reads cell voltage directly — at storage voltage around 3.6–3.7V, the transmitter interprets this as a depleted pack and flags low battery. This is not a fault with the cell. Connect the remote to its charger for a full charge cycle before use. Once the cell reaches 4.1V or above, the low-battery indicator will clear.

Frequently Asked Questions
My Hetronic ERGO-S won't power on at all after sitting in the site hut for a few months — is the battery gone?
Most likely the cell discharged below 2.5V during storage, which triggers BMS lockout — the protection circuit disconnects the cell to prevent damage, and the remote shows no signs of life. A standard charger may not kick-start a locked-out cell immediately. Connect the charger and leave it for 30 minutes before pressing the power button; some chargers apply a trickle pre-charge that brings the cell voltage back above the BMS recovery threshold of around 2.9V. If the remote still won't respond after a full charge cycle, the original cell has likely degraded past recovery and replacing it with a fresh 68303700 cell is the next step.
The ERGO-S drops out mid-operation every time I activate the hook — new battery fitted last week.
This is a BMS overcurrent trip caused by inrush current during solenoid or contactor activation. The cell was probably installed at storage voltage, which raises internal resistance enough that the voltage sag under load trips the BMS threshold. Fully charge the battery to 4.2V, then retest. If dropout continues on a fully charged cell, check that the transmitter contacts are clean and seated — a high-resistance connection amplifies the voltage sag during activation.
E-stop response on our ERGO-S feels slower than it used to — could the battery be causing this?
E-stop transmission response in the ERGO-S is voltage-dependent; below roughly 3.5V under load, the transmitter's RF output power drops and signal latency increases. An aged cell with capacity fade will sag under load even if the charge indicator looks normal. Swap in a fresh 68303700 cell, charge it fully, and verify the resting voltage reads 4.1V or above before running safety-critical lifts.
