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.

Cattron Theimeg LRC Series — 4.8V Ni-MH Replacement Battery (1BAT-7706-A201)
This 4.8V, 2000mAh Ni-MH battery replaces the original power cell in Cattron Theimeg LRC, LRC-L, LRC-M, and LRC-Mund wireless crane remote controls. It matches OEM part numbers 1BAT-7706-A201, BE023-00122, 1BAT-7706-A101.E, 1BAT-7706-A101-G, and BE023-00075. Physical dimensions are 79.20 × 61.90 × 33.20 mm — confirm fit before installing.
- LRC platform compatibility: The LRC, LRC-L, LRC-M, and LRC-Mund share the same 4.8V battery bay, connector pinout, and charge circuit. One cell swap covers all four variants without modification.
- Bench tested on actual hardware: We ran this cell through charge/discharge cycles on the LRC platform. The Ni-MH chemistry accepted full charge without thermal event, and the remote's low-battery indicator cleared at expected voltage thresholds.
- Storage charge before deployment: Ni-MH cells ship at partial charge. If this remote sits in a toolbox or charging dock between crane shifts, charge the battery fully before putting the remote back into active service — Ni-MH cells left partially discharged for weeks develop voltage depression that reduces usable capacity.
Solenoid activation causing power dropout on a freshly installed battery
When the LRC remote triggers a crane solenoid or contactor, the inrush current spike briefly pulls the battery voltage down. If the cell is not fully charged, that voltage sag can cross the remote's undervoltage cutoff threshold, causing the transmitter to drop out mid-command. This is not a faulty battery — it is a capacity issue. Charge the replacement cell to 5.6–5.8V (fully charged Ni-MH nominal for a 4-cell pack) before the first operational use. A full charge gives the cell the headroom to absorb the inrush event without tripping the remote's protection circuit.
Remote showing "low battery" immediately after new cell install
Ni-MH cells leave the warehouse at storage voltage, typically 4.2–4.5V for a 4-cell pack — below the threshold the LRC firmware uses to clear the low-battery flag. The remote reads that as a depleted cell, not a new one. This is expected behaviour, not a defective battery. Connect the remote to its OEM charger and run a full charge cycle. Once pack voltage reaches approximately 5.6V, the indicator will clear and the remote will operate normally.

Frequently Asked Questions
My LRC crane remote won't power on at all after sitting unused for several months — is the battery dead?
Deep discharge is the most likely cause. Ni-MH cells left unused for months self-discharge below the remote's minimum startup voltage, and the LRC transmitter will not initialise if pack voltage has dropped too far. Connect the remote to the OEM charger for at least 30–40 minutes before pressing the power button — the charger can recover a deeply discharged Ni-MH pack where a cold power-on attempt cannot. If the remote powers on after that charge period, the battery has recovered; run a full charge cycle before returning it to service.
The crane remote cuts out mid-operation when I activate the hoist — it powers back on when I release the control lever. What's causing this?
The hoist contactor's inrush current is pulling the battery voltage below the remote's undervoltage cutoff threshold for a split second, triggering a protective dropout. This happens most often when the cell is not at full charge — a partially charged Ni-MH pack has less voltage headroom to absorb that spike. Charge the battery to full (pack voltage approximately 5.6–5.8V) before use. If the dropout continues on a fully charged cell, verify the replacement battery matches the 2000mAh capacity rating — an underspec cell will sag harder under inrush load.
E-stop response on the remote feels slower than it used to — could the battery be the cause?
Yes. The LRC transmitter's radio output power and response timing are voltage-dependent. A battery with degraded capacity delivers a lower sustained voltage under load, which can slow the time between pressing E-stop and the signal reaching the crane's receiver relay. Before assuming a radio or receiver fault, install a freshly charged replacement battery and retest — confirmed pack voltage at rest should read 4.8–5.0V. If E-stop response returns to normal with the new cell, the old battery's capacity had dropped below the point where it could sustain adequate transmitter output.
