These remotes operate industrial cranes and hoisting equipment wirelessly, so a dead battery stops lifting operations until the cell is swapped. Dimensions are 68.00 × 36.00 × 10.00mm — verify these against your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eisar-control 3 and isar-control compatibility:\u003c\/strong\u003e\n    Both remotes run a single Li-Polymer cell on the same 3.7V rail with the same physical footprint and connector orientation. One cell covers both units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell under the switching loads typical of crane remote solenoid activation. The BMS held steady through repeated inrush events without tripping the protection circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eIdle-period charge maintenance:\u003c\/strong\u003e\n    Crane remotes often sit unused for weeks between jobs. If the cell drops below 2.5V during storage, the BMS enters deep-discharge lockout and the remote will not power on. Connect the charger for at least 30 minutes before first use after any extended idle period to bring the cell above the BMS recovery threshold.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePower dropout during solenoid or relay activation on the isar-control 3\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSolenoid activation pulls a short inrush current spike that a depleted or undersized cell cannot sustain. When the voltage sags below the BMS cutoff threshold during that spike, the remote drops out mid-operation. This cell's 3000mAh capacity provides the current headroom needed to absorb that inrush without triggering the protection circuit. Always start crane operations with a fully charged cell — a cell at 50% charge has measurably less headroom against inrush spikes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eisar-control 3 showing low-battery warning immediately after installing a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCells ship at storage voltage, typically around 3.6V — just below the threshold the isar-control 3 firmware uses to clear the low-battery flag. The remote is not faulty and the cell is not defective. Plug the remote into the charger and bring the cell to a full charge before use. Once voltage reaches approximately 4.1–4.2V, the warning clears and the remote operates normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360042582106,"sku":"BWCS-MLC300BL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360042614874,"sku":"BWCS-MLC300BL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360042647642,"sku":"BWCS-MLC300BL-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MLC300BL-1.webp?v=1778610729","url":"https:\/\/batteryweb.com\/products\/meiller-isar-control-3-replacement-battery-37v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
