It matches the original voltage rail and connector so the device can complete its power-on self-test. Capacity is 3000mAh (36Wh) — drawn from the product specification, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCardioaid 930 \/ 940 \/ 950 \/ MC+ platform:\u003c\/strong\u003e\n    All four models share the same battery bay format, 12V power rail, and BMS handshake protocol. The OEM part numbers 59439-6 and 110086-A cross-reference directly to this pack across the full series.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, self-test trigger, and load draw on the Cardioaid platform. The BMS accepted the pack without a fault flag, and the device completed its internal verification cycle cleanly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the Cardioaid run its full power-on self-test without interruption. Medical defibrillators run a BMS verification sequence at startup — cutting power mid-cycle forces a false battery fault that persists until the next complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCardioaid self-test failure after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Cardioaid series runs a charge-state verification during self-test. A fresh Ni-MH cell can read slightly below the BMS pass threshold on the first cycle because the cell voltage hasn't stabilised after shipping. This is a chemistry behaviour, not a faulty battery. Run one full charge-to-discharge cycle before using the device clinically — after that cycle, the BMS learns the cell's actual capacity curve and self-test passes consistently.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggers immediately on a fully charged pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the Cardioaid alarms low battery right after a confirmed full charge, the BMS is comparing resting cell voltage against a threshold calibrated to a conditioned OEM cell. A new Ni-MH cell sitting at 12V nominal can dip transiently under load on its first few cycles, tripping the alarm before actual depletion. Complete one full discharge down to 10.8V — roughly 0.9V per cell — then recharge fully. After that conditioning cycle, the alarm threshold aligns with the cell's actual output curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381436547162,"sku":"BWCS-SWC930MD-1","price":100.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381436579930,"sku":"BWCS-SWC930MD-2","price":117.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381436612698,"sku":"BWCS-SWC930MD-3","price":130.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SWC930MD-1.webp?v=1778900853","url":"https:\/\/batteryweb.com\/products\/simonson-wheel-defibrillator-cardioaid-930-replacement-battery-12v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
