The WTS700 is a wireless secondary panel used with ADT alarm systems for remote control and monitoring. This cell replaces OEM part P69NV19 when the original no longer holds adequate charge to keep the panel operational.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWTS700 panel compatibility:\u003c\/strong\u003e\n    The WTS700 operates on a 3.8V Li-Polymer cell because the panel's wireless comms module and touchscreen controller share a single low-voltage power rail. Swapping to any other voltage or chemistry causes the panel to fault on startup or refuse to charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the WTS700 charge cycle and confirmed the BMS accepted the cell without triggering a fault code. Float voltage stabilised at 4.35V, consistent with the panel's charge controller spec.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation charge conditioning:\u003c\/strong\u003e\n    Do not run a zone diagnostic or alarm test immediately after fitting this battery. Allow the panel to sit on mains power for 24–48 hours so the cell reaches full float charge. Running a test before this window often causes the panel to report a low battery fault even though the cell is functional.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the WTS700 reports low battery hours after a new cell is fitted\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe WTS700's onboard charge controller does not mark the battery as fully charged until the cell has completed a full float-charge cycle. A freshly fitted cell ships at a partial state of charge — typically 40–60%. Until the panel's BMS has completed its acceptance cycle, it continues to flag a low battery warning. This is not a fault with the replacement cell. Leave the panel connected to mains for at least 24–48 hours and the warning will clear once the cell reaches 4.35V float.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWTS700 losing alarm programming during a mains power outage after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the panel loses its programming configuration during a mains outage shortly after a battery replacement, the new cell had not yet been accepted by the BMS as a valid backup source. The panel's memory retention circuit draws from the battery the moment mains drops — if the cell is below the BMS acceptance threshold, the panel treats it as absent and cannot sustain programming. Fit the replacement cell, restore mains power, and allow a full 48-hour conditioning window before testing backup behaviour. After conditioning, confirm the cell reads at or above 3.6V on standby.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309822115930,"sku":"BWCS-HYW700BT-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309822148698,"sku":"BWCS-HYW700BT-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309822181466,"sku":"BWCS-HYW700BT-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYW700BT-1.webp?v=1777868261","url":"https:\/\/batteryweb.com\/products\/adt-wts700-resideo-7-wireless-secondary-color-touchscreen-replacement-battery-38v-2800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
