It fits the ECG Cardisuny C120 and ME Cardisuny C120 variants. OEM part number is HHR-16A8W1.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eC120 platform compatibility:\u003c\/strong\u003e\n    The ECG and ME Cardisuny C120 variants share the same 9.6V battery rail, connector housing, and BMS handshake protocol — one battery covers both units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the C120's charge and discharge sequence. The BMS accepted the cell, completed its verification handshake, and held voltage within the expected operating window across all test cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test requirement:\u003c\/strong\u003e\n    After fitting this battery, let the C120 complete its full power-on self-test without interruption. The device runs a BMS verification routine at startup — cutting power during this sequence triggers a false battery fault that sticks 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\"\u003eC120 not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Cardisuny C120 runs a multi-stage BMS verification during boot. A new Ni-MH cell fresh from storage may sit at a resting voltage slightly below the threshold the BMS expects to see at the start of that sequence. The device interprets this as a fault and halts before the ECG interface loads. Charge the battery fully on the C120 charger first, then power on — this brings resting voltage to the level the boot routine requires.\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 on the first one to three cycles with a new Ni-MH cell. The C120's BMS compares internal resistance and voltage recovery against a stored OEM chemistry profile. A new cell hasn't been conditioned yet, so its recovery curve doesn't match the profile threshold — the alarm fires even though capacity is present. Run one complete charge and discharge cycle before clinical use. After that cycle, the BMS re-evaluates the cell and the alarm clears at normal charge levels.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381464432730,"sku":"BWCS-FDC120MD-1","price":72.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381464465498,"sku":"BWCS-FDC120MD-2","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381464498266,"sku":"BWCS-FDC120MD-3","price":95.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FDC120MD-1.webp?v=1778900983","url":"https:\/\/batteryweb.com\/products\/fukuda-ecg-cardisuny-c120-replacement-battery-96v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
