It replaces OEM part numbers 120122 and BATT\/110122. The Cardiomed 3 ECG is a clinical-grade cardiac monitoring device used in ambulatory and point-of-care settings, so battery reliability directly affects patient workflow continuity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCardiomed 3 ECG fit:\u003c\/strong\u003e\n    The Cardiomed 3 platform uses a fixed 9.6V Ni-MH cell pack with a specific connector and BMS handshake tied to that voltage rail. This replacement matches the same cell configuration, connector pinout, and charge termination profile the device expects.\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 bench. The BMS accepted the new pack without flagging a chemistry mismatch, and charge termination fired correctly at full capacity. Voltage held steady across the load profile typical of an ECG trace acquisition cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the Cardiomed 3 complete its full power-on self-test without pressing any keys or interrupting the boot sequence. The device runs a BMS verification at startup, and cutting that sequence short causes a persistent false battery fault that clears only on a full cold 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 Cardiomed 3 alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Cardiomed 3 BMS uses threshold values calibrated against the original OEM cell's internal resistance and charge curve. A new replacement cell has a slightly different charge profile in its first few cycles, which can sit outside the BMS acceptance window at startup. The device interprets this as a low-charge condition even when the cell is physically full. One complete charge-discharge cycle on the new pack recalibrates the BMS read and clears the false alarm.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCardiomed 3 not powering on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–3% per day, so a battery stored for several weeks can drop below the BMS recovery threshold — typically around 8.4V on a 9.6V pack. Below that voltage, the device BMS blocks startup as a protection measure and the unit appears dead. Connect the Cardiomed 3 to mains charge and leave it for a minimum of 15 minutes before attempting to power on. Once voltage recovers above 8.4V, normal boot resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381496545370,"sku":"BWCS-DBT350MD-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381496578138,"sku":"BWCS-DBT350MD-2","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381496610906,"sku":"BWCS-DBT350MD-3","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DBT350MD-1.webp?v=1778901249","url":"https:\/\/batteryweb.com\/products\/dego-cardiomed-3-ecg-replacement-battery-96v-1700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
