These monitors are used for continuous bedside and transport vital signs surveillance including ECG, SpO2, and NIBP. Capacity is 24.42Wh as rated by the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eC80 and NC-series shared platform:\u003c\/strong\u003e\n    The C80, NC8A, NC10, and NC10A share the same battery bay geometry, connector pinout, and BMS communication protocol. All four models accept this pack without modification to the battery compartment or firmware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on a C80 unit and confirmed full BMS handshake, charge acceptance to rated capacity, and normal charge-status display on the monitor screen. The BMS flagged no fault codes across initial charge and discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the C80 to complete its full power-on self-test without interruption. The monitor runs a BMS verification routine at startup — interrupting it mid-cycle triggers a persistent battery fault flag that will not clear 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 C80 alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe C80's BMS stores a learned capacity baseline from the previous cell. When a new pack is installed, the BMS compares real-time cell impedance against that stored profile — and a fresh cell with no charge history reads differently than a conditioned OEM pack. This mismatch can trigger a low-battery alarm even at full charge voltage. Running one complete charge-discharge cycle lets the BMS recalibrate its state-of-charge estimate to the new cell. After that conditioning cycle, the alarm threshold aligns correctly and the fault clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMonitor will not power on after battery was stored outside the device\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If this pack sat in a warehouse or shelf for several months, cell voltage may have dropped below the C80's BMS recovery threshold — typically around 9V for an 11.1V three-cell pack. The BMS will refuse to boot the device rather than draw from a potentially over-discharged cell. Place the battery on the C80's internal charger using AC mains for at least two hours before attempting to power on. If the charge indicator shows activity, the BMS has accepted the cell and recovery is in progress.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381444477018,"sku":"BWCS-CMA800MD-1","price":123.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381444509786,"sku":"BWCS-CMA800MD-2","price":147.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381444542554,"sku":"BWCS-CMA800MD-3","price":164.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CMA800MD-1.webp?v=1778900837","url":"https:\/\/batteryweb.com\/products\/comen-c80-replacement-battery-111v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
