It carries a 3400mAh (37.74Wh) capacity to support continuous vital sign monitoring in clinical and home healthcare settings. Voltage and cell count match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBPM-770 compatibility:\u003c\/strong\u003e\n    The BPM-770 uses an 11.1V three-cell Li-ion configuration. This pack matches that voltage rail and connector format, so the device power management circuit recognises it without triggering a mismatch fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-discharge cycles and confirmed the BMS handshake completed without error flags. Capacity came in at rated spec by cycle three, which is normal for a fresh Li-ion cell entering its first conditioning cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the BPM-770 to complete its full power-on self-test without interrupting the boot sequence. Medical device BMS verification runs at startup — cutting power mid-sequence registers a battery fault that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBPM-770 not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BPM-770 runs a BMS verification routine during startup that checks cell voltage, internal resistance, and chemistry signature against stored OEM thresholds. A new replacement cell can sit slightly outside those thresholds on the first boot — not because the cell is faulty, but because the BMS hasn't yet logged a completed charge-discharge cycle against this specific cell. The device may stall at the self-test screen or reboot mid-sequence. Completing one full charge-discharge cycle before clinical deployment clears this and allows the BMS to calibrate its state-of-charge model accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BPM-770 charge IC applies a conservative current ceiling when it encounters a new or unfamiliar cell — this is a protective behaviour, not a fault. On the first charge, the IC holds back from the final absorption phase until it has profiled the cell's voltage curve. The result looks like a charge that stops at 90–95% and doesn't advance. Run a full charge cycle uninterrupted, then discharge the device through normal monitoring use, and recharge fully — the IC will reach 100% and hold it from the second cycle onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381446049882,"sku":"BWCS-BLM900MX-1","price":119.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381446082650,"sku":"BWCS-BLM900MX-2","price":138.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381446115418,"sku":"BWCS-BLM900MX-3","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLM900MX-1.webp?v=1778900875","url":"https:\/\/batteryweb.com\/products\/bionics-bpm-770-replacement-battery-111v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
