These monitors are used in clinical settings to track heart rate, SpO2, blood pressure, and temperature. Cross-reference OEM part numbers 022-000084-00, CL-18650-26H3S1P, or LIV111C2200S01B before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStar 8000, Star 8000 E, and M2000A compatibility:\u003c\/strong\u003e\n    All three models share the same 10.8V battery bay, connector pinout, and BMS handshake protocol. The same cell configuration and charge IC communication work across this monitor family without 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 Star 8000 startup sequence and confirmed the BMS handshake completed without fault codes. The charge IC accepted the cell and advanced through all charge stages to full capacity on the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap power-on sequence:\u003c\/strong\u003e\n    After installing this battery, allow the monitor to complete its full power-on self-test without interruption. The Star 8000 runs a BMS verification step at boot — cutting power during this phase triggers a false battery fault that persists until the next clean reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eStar 8000 low-battery alarm firing immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Star 8000's BMS compares the new cell's internal resistance profile against stored OEM chemistry thresholds. A fresh cell that has not completed a full charge-discharge cycle reads outside that threshold window, and the monitor flags it as degraded even when voltage is correct. This is not a fault with the replacement cell. Run one complete charge-discharge cycle and the BMS recalibrates its reference point. After that cycle, the low-battery alarm should clear and the charge indicator should track accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMonitor will not power on after the battery has been in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the cell voltage has dropped below approximately 2.5V per cell (7.5V pack total), the Star 8000's BMS enters deep-discharge protection and blocks output entirely — the monitor shows no response at all. Connect the battery to the monitor on mains power and leave it for 20–30 minutes before attempting to power on. This allows the charge IC to apply a recovery trickle current and bring the pack back above the BMS re-enable threshold of around 9V before normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381446705242,"sku":"BWCS-CMS800MD-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381446738010,"sku":"BWCS-CMS800MD-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381446770778,"sku":"BWCS-CMS800MD-3","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CMS800MD-1.webp?v=1778900876","url":"https:\/\/batteryweb.com\/products\/comen-star-8000-replacement-battery-108v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
