It replaces OEM part numbers P-0466 and R-0692-1. The battery sits inside a slim 214.23 x 23.57 x 22.56mm cell pack that slots directly into the device bay.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHeartscreen 80G and 112B platform compatibility:\u003c\/strong\u003e\n    Both models share the same 6V battery rail, connector pinout, and BMS handshake protocol — one cell pack covers the full range listed in the fit model data.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Heartscreen's charge IC and confirmed BMS communication, voltage hold at load, and correct charge termination without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installation, let the device complete its full power-on self-test without interruption. The Heartscreen 80G runs a BMS verification sequence at startup — cutting power during that window 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\"\u003eWhy the Heartscreen 80G alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Heartscreen's BMS uses a threshold calibrated to the charge history of the cell it learned on. A new Ni-MH cell hasn't built that baseline, so the BMS misreads the internal resistance and flags a low-battery condition even at full charge. This clears after one complete charge-discharge cycle. Run the device through one full session to near-empty, then charge fully before clinical use — the alarm will not recur.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day. If the battery spent weeks or months in a warehouse, it may arrive below the Heartscreen's BMS recovery threshold — typically around 5.0V for a 6V pack. The BMS will refuse to boot rather than draw from a cell it reads as critically low. Connect the charger and leave it for a full uninterrupted charge cycle before attempting power-on. If the charge indicator stays dark after 30 minutes, disconnect and reconnect to force the charge IC to restart its recovery sequence.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381474951258,"sku":"BWCS-ICD800MD-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381474984026,"sku":"BWCS-ICD800MD-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381475016794,"sku":"BWCS-ICD800MD-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ICD800MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/innomed-heartscreen-80g-ekgecg-replacement-battery-6v-3500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
