Cameron Sino 3400mAh 7.4V Battery Cavotec M9-1051-3600 EX MC-3 MC-3000

Compatible Crane Remote Battery

This 3400mAh lithium-ion pack replaces the original power source for Cavotec M9-1051-3600 EX, MC-3 and MC-3000 crane remote controls. It delivers 7.4 volts and 25.16Wh in a form factor measuring 93.58 by 41.28 by 27.45 millimetres. The pack weighs 130.0 grams and includes a fully decoded chip for direct communication with the handset. It is intended for operators who need a fresh, safety-certified cell for daily lifting operations.

Voltage and Capacity Limits

The 7.40-volt output is fixed by the two-cell lithium-ion chemistry and cannot be adjusted for other remote models. Capacity is rated at 3400 milliamp-hours, which defines the runtime ceiling between charges. The protection circuit prevents overcharge, over-discharge, over-voltage and short-circuit events, but it also means the pack will shut down if current draw exceeds its design envelope. Users requiring longer shifts must swap packs rather than expect extended runtimes from this unit.

Direct Replacement for Worn Packs

This battery upgrades a depleted or ageing original that no longer holds sufficient charge for a full work cycle. The jump is worth it when the remote shows reduced operating time, unexpected shutdowns or physical swelling of the old cell. It is not for operators who need a higher-voltage system, a different connector pinout or a hot-swap docking station that the remote does not support. Compatibility must be verified against the M5-1051-3600 part number before purchase.
