It fits a medical-grade respiratory device used for ventilation support in clinical wards, emergency transport, and field settings. Match the OEM part number before fitting — the V1 platform uses several battery variants across production runs.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV1 ventilator platform compatibility:\u003c\/strong\u003e\n    The V1 series uses multiple OEM part numbers — CMLI2X3N003B, CMLI1X3N004B, CML12X3N003B, CML11X3N004B, and CMLI2X3I003B — across hardware revisions. These share the same voltage rail, cell format, and BMS communication protocol, which is why a single replacement cell services the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran full charge and load cycles on this cell under the V1's reported draw profile. The BMS accepted the handshake without fault codes, and the charge IC brought the pack to capacity without triggering an early cutoff.\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 sequence at startup — cutting power during this window logs a false battery fault that persists until the next full reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eV1 ventilator not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe V1's boot sequence includes a BMS learn step that reads cell voltage, internal resistance, and charge state before clearing for clinical use. A new cell that hasn't completed its first full charge cycle can present a state-of-charge value the device BMS flags as out of range. This causes the boot sequence to stall or abort. Charge the replacement pack fully before first installation, then allow the device to boot without interruption.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the device BMS is calibrated to OEM cell chemistry and the new cell's voltage curve reads slightly different on the first cycle. The alarm threshold is based on voltage drop under load, and a new cell can sag more than a conditioned cell during the first few discharge cycles. Run one complete charge-to-discharge cycle before placing the unit back in clinical rotation. After that cycle, the BMS recalibrates its low-battery cutoff point to match the replacement cell's actual discharge curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381402140762,"sku":"BWCS-CGV100MX-1","price":350.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381402173530,"sku":"BWCS-CGV100MX-2","price":418.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381402206298,"sku":"BWCS-CGV100MX-3","price":469.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CGV100MX-1.webp?v=1778900535","url":"https:\/\/batteryweb.com\/products\/comen-v1-portable-ventilator-replacement-battery-108v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
