It replaces OEM part numbers CMLI2X3N003B, CMLI1X3N004B, CML12X3N003B, CML11X3N004B, and CMLI2X3I003B. The V1 is a portable mechanical ventilator used for respiratory support in transport, home care, and clinical settings.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV1 Ventilator battery platform:\u003c\/strong\u003e\n    All listed OEM part numbers share the same 10.8V three-cell series configuration, connector pinout, and BMS communication protocol used by the V1's charge management circuit. Swapping between these part numbers does not require firmware changes or hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through the V1's startup self-test sequence and monitored the BMS handshake under simulated ventilation load. The protection circuit responded correctly to charge termination and low-voltage cutoff thresholds consistent with the OEM specification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the V1 to complete its full power-on self-test without interruption. The device runs a BMS verification cycle at startup — cutting power during this sequence stores a false battery fault in the device log that will persist until the next complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the COMEN V1 draws harder on a new cell than on an aged OEM battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell has not yet stabilised its internal resistance profile. In the first several charge-discharge cycles, the V1's motor-driven blower and pressure regulation circuitry can pull instantaneous current spikes the BMS interprets as overload on an unconditioned cell. This can trigger a brief protective cutoff that clears on its own but looks like a fault during clinical checks. Running one complete charge-discharge cycle before putting the battery into clinical rotation allows the BMS to calibrate its thresholds against the actual cell behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stops before 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn first charge, the V1's charge IC applies a conservative current limit while it profiles the new cell's capacity curve. This is normal behaviour — the indicator stalls typically in the 90–95% range and then advances slowly. It is not a faulty battery or charger. Run the first charge to completion without interrupting it, then discharge normally through device use before the second charge; the indicator will read accurately from that point forward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381402271834,"sku":"BWCS-CGV100MD-1","price":275.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381402304602,"sku":"BWCS-CGV100MD-2","price":329.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381402337370,"sku":"BWCS-CGV100MD-3","price":369.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CGV100MD-1.webp?v=1778900535","url":"https:\/\/batteryweb.com\/products\/comen-v1-portable-ventilator-replacement-battery-108v-3300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
