It maintains alarm functionality and cellular communication during mains power outages. Capacity is 7800mAh (28.86Wh) — matched to the original cell specification.\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 all-in-one panel variants share the same battery bay dimensions, connector polarity, and BMS handshake protocol — this cell fits both 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 a full charge and simulated mains-loss event. The BMS held communication with the panel and passed the low-battery threshold check at 3.4V without triggering a fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation float charge period:\u003c\/strong\u003e\n    Do not run a zone test or siren test immediately after fitting this cell. Allow 24–48 hours on float charge first. A new cell installed below 3.5V will cause the panel to flag a low-battery warning until the charge stabilises — this is normal BMS behaviour, not a fault with the battery.\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 keeps reporting low battery after a new cell is fitted\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Command panel samples backup battery voltage on a fixed polling cycle. A new cell often arrives at a storage charge around 3.5–3.6V — below the panel's \"healthy\" threshold. Until the onboard charger brings the cell to full float voltage, the panel will continue to log a low-battery event. This is not a faulty battery or a wiring problem. Leave the panel on mains power for 48 hours and the alert will clear automatically once the cell crosses the acceptance threshold.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm loses all programming during a power outage with a new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the panel drops its configuration during an outage, the backup cell has not yet been accepted by the BMS — it cannot sustain panel memory voltage under load. This typically happens when the replacement cell was fitted and the system was tested within the first few hours. The fix is straightforward: restore mains power, allow a full 48-hour conditioning charge, then test again by pulling the mains lead. The panel should hold all zones and user codes at that point without any reprogramming needed.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309828112474,"sku":"BWCS-HYA200BT-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309828145242,"sku":"BWCS-HYA200BT-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309828178010,"sku":"BWCS-HYA200BT-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYA200BT-1.webp?v=1777868235","url":"https:\/\/batteryweb.com\/products\/adt-command-smart-security-panel-replacement-battery-37v-7800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
