It replaces OEM part HYLB-952. The ECG-1215 is a clinical-grade device used for 12-lead cardiac rhythm monitoring in hospital wards, clinics, and mobile diagnostic settings.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eECG-1215 platform fit:\u003c\/strong\u003e\n    The ECG-1215 uses a 14.8V four-cell Li-ion pack with a BMS that checks cell group voltages and temperature at startup. This replacement matches that voltage rail and connector pinout. The BMS handshake runs on power-on, not mid-session, so the pack either clears self-test or flags a fault before the device reaches the recording screen.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge-discharge runs on the ECG-1215 platform and confirmed the BMS cleared all self-test checks without triggering a battery fault. Cell balancing completed correctly across all four groups after the first full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After installing this battery, let the device run its full power-on self-test without pressing any buttons or cycling power. The ECG-1215 BMS runs a voltage verification sequence at boot. Interrupting that sequence logs a false battery fault that stays flagged until the next clean reboot from a fully charged state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ECG-1215 BMS flags a new battery as faulty on first boot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ECG-1215 BMS compares each cell group voltage against a stored threshold calibrated to the OEM cell chemistry. A new replacement cell ships at a partial state of charge, and its resting voltage curve does not yet match the learned profile from the original pack. This mismatch can trigger a low-battery or battery-fault warning on the first one or two boot cycles. Running one complete charge-discharge cycle lets the BMS re-characterise the pack and update its internal thresholds. After that cycle, the fault flag clears and does not return.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalling below 100% on the ECG-1215\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ECG-1215 charge IC applies a conservative taper current when it detects a new or unfamiliar cell pack — this is a built-in protection behaviour, not a fault. The charge cycle extends longer than normal on the first charge as the IC holds a lower termination threshold. Do not disconnect the charger early. Let the charge run to natural termination. After the first full charge, the IC updates its end-of-charge detection and subsequent charges complete to a full 16.8V termination voltage as expected.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381482651738,"sku":"BWCS-ECG215MD-1","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381482684506,"sku":"BWCS-ECG215MD-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381482717274,"sku":"BWCS-ECG215MD-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ECG215MD-1.webp?v=1778901171","url":"https:\/\/batteryweb.com\/products\/biocare-ecg-1215-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
