These portable ECG machines use a 12V Ni-MH pack to maintain operation during patient monitoring when AC power is unavailable. Voltage, capacity, and connector match the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eECG-108 and ECG-110 shared platform:\u003c\/strong\u003e\n    Both models run the same 12V battery rail and use identical connector orientation and BMS handshake protocol, which is why they share the HHR-12F25G1 part number across the range.\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-108 charge circuit and confirmed the BMS accepted the pack, completed charge termination correctly via delta-V detection, and held voltage under the device's acquisition load without triggering a low-battery cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test handling:\u003c\/strong\u003e\n    After installing this battery, allow the ECG-108 to complete its full power-on self-test without interruption. The device runs a BMS verification routine at startup — cutting power mid-sequence stores a false battery fault that persists until the next complete reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ECG-108 flags a battery fault on a fully charged new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe ECG-108 BMS sets its pass threshold based on the charge profile of a conditioned Ni-MH cell. A new, uncycled cell has slightly higher internal resistance and a flatter delta-V curve than a broken-in pack, so the device's charge IC may flag it as marginal on the first cycle. This is not a fault with the battery. Running one complete charge-discharge cycle through the device brings cell resistance within the BMS acceptance window. After that first cycle, the battery fault indicator clears and does not return.\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\"\u003eThe ECG-108 charge IC applies a conservative current limit when it detects a new cell with higher initial resistance. It terminates charge early rather than risk overcharge on an unconditioned pack. The display reads 80–90% even after several hours on charge. Run the device until it shuts down on battery, then place it back on charge — the IC recalibrates its termination threshold and the next charge cycle reaches full capacity, confirmed by a resting voltage above 13.5V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381505032282,"sku":"BWCS-ECG108MD-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381505065050,"sku":"BWCS-ECG108MD-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381505097818,"sku":"BWCS-ECG108MD-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ECG108MD-1.webp?v=1778901305","url":"https:\/\/batteryweb.com\/products\/kenz-cardico-ecg-108-replacement-battery-12v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
