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.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMC-3 and MC-3000 platform fit:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMonthly charge during idle periods:\u003c\/strong\u003e\n    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.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSolenoid activation causing power dropout on a freshly installed battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen 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.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery indicator immediately after new cell install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eReplacement 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.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360046284890,"sku":"BWCS-CMC300BL-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360046317658,"sku":"BWCS-CMC300BL-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360046350426,"sku":"BWCS-CMC300BL-3","price":39.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/cavotec-m9-1051-3600-ex-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
