It fits the ADT7AIO and ADT5AIO all-in-one panel variants. When mains power drops, this cell keeps the panel live, maintains sensor communication, and holds the connection to ADT monitoring services.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eADT7AIO and ADT5AIO compatibility:\u003c\/strong\u003e\n    Both panel variants run the same 3.7V battery rail with an identical connector and BMS handshake. One cell covers both models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Command panel's charge management circuit. The BMS accepted the cell cleanly, moved through the conditioning phase, and held float charge without triggering a fault code.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation panel behaviour:\u003c\/strong\u003e\n    Do not run a zone or siren test immediately after fitting this cell. The panel's charge controller needs 24–48 hours on float charge before the BMS reports a full battery status. Testing too early can produce a false low-battery alert on the panel display.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ADT Command panel reports low battery hours after a new cell is fitted\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Command panel does not read battery voltage directly — it reads a state-of-charge register inside the cell's BMS. A fresh Li-ion cell ships at partial charge, typically around 3.6–3.7V open circuit, which the BMS maps to roughly 40–60% capacity. The panel sees that register value and flags a low-battery condition even though the cell is new and functional. Once the panel's internal charger brings the cell to full float voltage (approximately 4.1–4.2V), the BMS updates the register and the low-battery warning clears. This process takes 24–48 hours on continuous mains power.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eADT Command panel loses all programming during a power outage after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eIf the panel has not accepted the new cell — meaning the BMS handshake is incomplete or the cell has not yet reached a sufficient charge threshold — it will not supply backup power when mains drops. The panel loses RAM-held configuration data and reverts to factory defaults. This is not a fault with the cell itself; it means the cell was fitted and then a power outage occurred before the 48-hour conditioning window closed. Restore mains power, allow a full 48-hour charge cycle, then confirm battery status reads normal on the panel before the next outage or test.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309828407386,"sku":"BWCS-HYA210BT-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309828440154,"sku":"BWCS-HYA210BT-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309828472922,"sku":"BWCS-HYA210BT-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYA210BT-1.webp?v=1777868235","url":"https:\/\/batteryweb.com\/products\/adt-command-smart-security-panel-replacement-battery-37v-10000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
