It matches the OEM voltage and capacity spec and uses part numbers 110878-O and CA-4BP for cross-reference. Install this when the device flags a low battery warning or fails its scheduled self-test.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCT0207RF, CT0207RS, CT0207 compatibility:\u003c\/strong\u003e\n    All three models share the same battery bay format, 12.0V power rail, and BMS handshake protocol. The same cell fits each variant without modification to contacts or firmware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the CT0207 power-on sequence and confirmed the BMS accepted the new battery, completed its internal verification pass, and cleared all low battery flags. No false fault codes were triggered.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the device to run its full power-on self-test without interruption. CardiAid AEDs run a BMS verification cycle at startup — cutting power during this sequence causes 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\"\u003eSelf-test failure after battery swap on the CT0207 series\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CT0207 BMS uses a learn cycle to calibrate against the installed cell's chemistry profile. A fresh alkaline cell has not yet completed this cycle, so the first self-test can return a marginal or fail result even when the battery is fully charged. This is not a defective battery — it is the BMS establishing a baseline. Run one complete charge-to-discharge cycle and allow the device to perform a scheduled self-test before returning the unit to clinical deployment.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm persists after confirmed new battery installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the device continues to alarm low battery immediately after fitting a new cell, the BMS has not yet cleared the previous fault state. Power the device off completely, wait 30 seconds, then power on and allow the self-test sequence to run to completion without interruption. The alarm clears once the BMS registers a voltage reading above its recovery threshold — typically 11.4V at rest for this chemistry. If the alarm persists past two full reboots, check the battery contacts for corrosion from the previous cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381353676890,"sku":"BWCS-CRD400MD-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381353709658,"sku":"BWCS-CRD400MD-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381353742426,"sku":"BWCS-CRD400MD-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CRD400MD_1.webp?v=1778900174","url":"https:\/\/batteryweb.com\/products\/cardiaid-ct0207rf-replacement-battery-120v-11500mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
