These units are used in clinical and mobile cardiac diagnostic settings where continuous power is non-negotiable. Voltage and capacity match the original cell pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e800C, ECG-101A, and ECG-300A compatibility:\u003c\/strong\u003e\n    All three models run the same 12V Ni-MH battery rail with an identical connector footprint and BMS handshake protocol. Swapping between these units does not require any reconfiguration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on the ECG-300A platform and confirmed the BMS accepted the new pack without throwing a chemistry mismatch fault. Charge acceptance was normal from the first cycle, and the protection circuit responded correctly to load termination.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the device to complete its full power-on self-test without interruption. Cardipia ECG units run a BMS verification step at startup — cutting power during this sequence triggers a false battery fault that will persist 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\"\u003eWhy the 800C shows a battery fault on the first boot after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Cardipia 800C uses a BMS learn cycle to validate the installed cell's charge state before clearing the battery status flag. A brand-new Ni-MH cell arrives at a partial state of charge, which sits below the threshold the device expects after a \"charged\" pack is installed. The BMS interprets this as a degraded or incompatible cell and holds the fault flag. Run one complete charge-discharge cycle before drawing any clinical conclusions from the battery indicator.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the Cardipia charge IC applies a conservative current limit to an unrecognised Ni-MH pack — it does not yet have a baseline delta-V curve to work from. The result is a charge cycle that terminates early or stalls below 100% on the display. This is not a cell fault. Run a second full charge immediately after the first completes and the charge IC will lock onto the correct termination point. By the third cycle the indicator should reach full charge consistently.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381520597082,"sku":"BWCS-ECG300MD-1","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381520629850,"sku":"BWCS-ECG300MD-2","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381520662618,"sku":"BWCS-ECG300MD-3","price":91.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ECG300MD-1.webp?v=1778901370","url":"https:\/\/batteryweb.com\/products\/cardipia-800c-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
