These are portable cardiac monitoring devices used in clinical and diagnostic settings. This cell replaces the original when capacity has dropped to the point where the unit no longer holds charge through a full patient session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eECG-1112, ECG-1112L, ECG-1201 platform:\u003c\/strong\u003e\n    All three models share the same 14.4V power rail, connector housing, and BMS handshake protocol. One cell fits all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the ECG-1112 platform. The BMS completed its self-test handshake and passed all voltage threshold checks after a single full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full power-on self-test without interruption. The ECG-1112 runs a BMS verification sequence at boot — cutting power mid-sequence stores a false 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\"\u003eDevice not completing boot sequence on new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ECG-1112 boot sequence includes a BMS handshake that checks cell voltage against a stored threshold. A new cell shipped in storage-state may sit just above or below the 12.0V minimum the device expects before it allows full boot. If the unit stalls at the initialisation screen, the BMS has flagged a low-cell condition rather than a hardware fault. Charge the battery fully before the first boot attempt — the charge IC targets 16.8V at full charge — and then power on the device without interruption.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge cycle, the ECG-1112 charge IC applies a conservative current limit to an uncharacterised cell. This causes the charge indicator to plateau at 90–95% and stop climbing. This is not a faulty battery — the charge IC has not yet mapped the cell's capacity curve. Run one complete charge-discharge-charge cycle and the indicator will read accurately at 16.8V termination voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381454733402,"sku":"BWCS-CRE112MD-1","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381454766170,"sku":"BWCS-CRE112MD-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381454798938,"sku":"BWCS-CRE112MD-3","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CRE112MD-1.webp?v=1778900876","url":"https:\/\/batteryweb.com\/products\/kelly-ecg-1112-replacement-battery-144v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
