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.

Cavotec M9-1051-3600 EX / MC-3000 Series — 7.4V Li-ion Replacement Battery (M5-1051-3600)
This is a 7.4V 2600mAh Li-ion battery for the Cavotec M9-1051-3600 EX, MC-3, and MC-3000 wireless crane remote controls. These remotes operate overhead cranes and hoists in industrial environments where a dead battery means halted lifts and delayed work. Voltage and capacity match the OEM specification exactly.
- MC-3 and MC-3000 platform fit: The M9-1051-3600 EX, MC-3, and MC-3000 share the same 7.4V two-cell architecture, connector pinout, and BMS handshake protocol — one battery covers all three variants without modification.
- Bench tested on actual hardware: We cycled this battery through full charge and discharge on a Cavotec MC-3000 remote. The BMS initialised cleanly, cell balancing engaged correctly, and the protection circuit held steady under solenoid activation inrush without tripping.
- Monthly charge during idle periods: Crane remotes often sit unused for weeks or months between jobs. Li-ion cells discharged below 2.5V per cell trigger BMS deep-discharge lockout. Connect the charger for at least 30 minutes once a month, even when the remote is not in active use, to keep cells above that threshold.
Solenoid activation causing power dropout on a freshly installed battery
When a crane remote fires a solenoid or relay, the inrush current can spike sharply for 20–50 milliseconds. If the battery's BMS has a low overcurrent threshold — common in cells at partial charge — this spike trips the protection circuit and cuts power to the remote. The dropout looks like the remote restarting or going blank mid-command. Charge the battery fully before first operational use; a cell sitting at storage voltage (around 3.7V per cell) has less headroom to absorb that inrush without tripping the BMS.
Remote showing low battery indicator immediately after new cell install
Replacement Li-ion batteries ship at storage voltage — typically 3.6–3.8V per cell, or roughly 50–60% state of charge. The MC-3000 remote reads cell voltage directly and flags anything below its low-battery threshold as a warning, even on a brand-new pack. This is not a fault with the battery. Connect the battery to the Cavotec charger and run a full charge cycle before use — the low-battery indicator should clear once both cells reach 4.1–4.2V each.

Frequently Asked Questions
My Cavotec MC-3000 remote won't power on at all after sitting in storage for a few months — is the battery dead?
Most likely the battery entered deep-discharge BMS lockout during storage. When Li-ion cells drop below 2.5V per cell, the protection circuit disconnects the pack and a standard charger may not wake it immediately. Connect the Cavotec charger and leave it for 30–45 minutes without touching the remote — the BMS on these packs has a trickle-recovery mode that can bring cells back up if they haven't dropped below the recovery floor. If the charger LED doesn't change state after 45 minutes, the cells have degraded past recovery and the battery needs replacement.
The crane remote cuts out for a split second every time I press a command button — then comes back on its own. What's happening?
This is a BMS overcurrent trip triggered by the solenoid or relay inrush current on each button press. The spike draws more current than the BMS threshold allows, the circuit opens briefly, then resets. It happens most often when the battery is below full charge because internal resistance is higher at lower states of charge. Charge the battery to 100% before use and test again — if dropout persists at full charge, the battery's cells have degraded and internal resistance has risen permanently, requiring a new pack.
The E-stop on my Cavotec remote takes noticeably longer to respond than it used to. Could the battery be causing that?
E-stop response time on the MC-3000 platform is voltage-dependent — the radio transmitter output power drops as cell voltage sags, which increases the time between button press and signal reception at the crane receiver. A battery with degraded cells will sag in voltage under even light transmit load. Check the battery voltage under load with a multimeter: if it reads below 7.0V while the remote is actively transmitting, the cells are no longer holding sufficient charge and the pack should be replaced before any safety-critical lift operations.
