It replaces OEM part number HYLB-1171 directly. Both models run the same voltage rail and use the same BMS communication protocol.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eECG-6A and ZQ-1206 compatibility:\u003c\/strong\u003e\n    Both devices share the HYLB-1171 form factor, 14.8V nominal voltage, and the same four-pin connector with BMS data line. A battery that passes handshake on one will pass on the other — the charge IC reads cell chemistry the same way across both units.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the ECG-6A power-on sequence and monitored BMS handshake on the data line. The charge controller accepted the cell on first insertion, and the self-test cycle completed without a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full power-on self-test without pressing any buttons or connecting a patient lead. Medical-grade BMS firmware runs a cell verification check at boot — interrupting it locks in a false battery fault that won't clear until a clean reboot from a full-charge state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ECG-6A runs a BMS learn cycle on first use with a new cell. If the device powers off, reboots, or receives a keypress during that initial self-test, the firmware logs a battery authentication fault. This fault persists across subsequent power cycles because the BMS hasn't stored a confirmed capacity baseline. Charge the battery to full, then power on and leave it untouched through the entire boot sequence — typically 15–20 seconds — before use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalling below 100% on the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew Li-ion cells ship at a partial state of charge, and the ECG-6A charge IC applies a conservative current limit on an unrecognised cell until it reads a full voltage profile. This causes the charge bar to slow significantly above 80% and sometimes stall at 95–98% on the first cycle. This is not a fault — it clears after one complete charge-to-discharge-to-full cycle. After that first cycle the charge IC recalibrates and the indicator tracks correctly to 14.8V full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381363540058,"sku":"BWCS-ZNR120MD-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381363572826,"sku":"BWCS-ZNR120MD-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381363605594,"sku":"BWCS-ZNR120MD-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZNR120MD-1.webp?v=1778900304","url":"https:\/\/batteryweb.com\/products\/zoncare-atom-ecg-6a-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
