It carries OEM part number 022-000092-00 and fits the H3 directly. The H3 is a bedside vital signs monitor used in hospitals, clinics, and transport settings where uninterrupted power matters.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCOMEN H3 platform fit:\u003c\/strong\u003e\n    The H3 runs a single 11.1V Li-ion pack tied to a BMS that validates cell voltage and chemistry signature at boot. Cells outside the expected voltage window cause the device to reject the battery before powering on. This pack matches that voltage rail and passes the BMS handshake without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on the H3 platform. The BMS completed cell verification at startup and registered a full state of charge without triggering a battery fault. Capacity held consistent across the first three cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the H3 complete its full power-on self-test without interruption. The device runs a BMS verification sequence during boot, and cutting power mid-sequence creates a persistent false battery fault that survives 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\"\u003eWhy the H3 alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe H3's charge IC applies a conservative voltage threshold for new cells on the first cycle. A freshly charged new pack may read 97–99% state of charge internally but still fall short of the BMS acceptance threshold calibrated for a conditioned cell. This triggers a low-battery alarm even though the pack is not depleted. Run one complete charge-to-discharge cycle before clinical deployment — after that cycle, the BMS recalibrates against the actual cell behaviour and the alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eH3 will not power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the pack voltage drops below approximately 9V, the H3's BMS enters deep-discharge lockout and refuses to power the device. The fix is a slow pre-charge — place the battery on the H3 charger and leave it connected for at least 90 minutes before attempting to boot the monitor. This allows the charge IC to recover the cell voltage above the BMS re-initialisation threshold, typically 10.5V, before normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381450408026,"sku":"BWCS-CMH300MD-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381450440794,"sku":"BWCS-CMH300MD-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381450473562,"sku":"BWCS-CMH300MD-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CMH300MD-1.webp?v=1778900876","url":"https:\/\/batteryweb.com\/products\/comen-h3-replacement-battery-111v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
