It fits the ECG-101 directly using OEM part number NS200D1374850. The ECG-101 is a portable cardiac monitoring device used in clinical and point-of-care settings to record and analyze heart electrical activity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eECG-101 platform fit:\u003c\/strong\u003e\n    The NS200D1374850 cell block matches the ECG-101's 12V power rail, connector pinout, and BMS handshake protocol. No modification is needed to the battery bay or charging circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the ECG-101's charge and discharge profile. The BMS accepted the new cell on first insertion and completed its verification routine without triggering a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After installing this battery, allow the ECG-101 to complete its full power-on self-test without powering the device off mid-sequence. Interrupting the startup BMS verification cycle can log a persistent battery fault that only clears on 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\"\u003eECG-101 not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ECG-101 runs a BMS learn cycle during its first few boot sequences with a new cell. If the device stalls mid-boot or loops back to the startup screen, the BMS has not yet validated the new cell's charge state. Charge the battery fully before the first power-on — the onboard charge IC targets 14.4V at termination for a 12V Ni-MH pack. Once a full charge completes, boot the device and let the self-test run to completion without interruption.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggers immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the ECG-101's BMS compares cell voltage against thresholds calibrated to the original factory cell's charge curve. A new Ni-MH cell has a slightly different voltage profile in its first five to ten cycles, which the BMS can read as below threshold even when the cell is fully charged. Run one complete charge-discharge cycle outside of clinical use to let the BMS recalibrate its low-voltage reference point. After that first conditioning cycle, the alarm threshold aligns correctly with the new cell's actual state of charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381520302170,"sku":"BWCS-ECG101MD-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381520334938,"sku":"BWCS-ECG101MD-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381520367706,"sku":"BWCS-ECG101MD-3","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ECG101MD-1.webp?v=1778901370","url":"https:\/\/batteryweb.com\/products\/biocare-ecg-101-replacement-battery-12v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
