It replaces OEM part 300-06868. When mains power drops, this cell takes over — keeping security monitoring and alert functions running until power restores.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eProSeries and Prosixlcdkp compatibility:\u003c\/strong\u003e\n    Both units share the same 7.2V backup rail, connector pinout, and BMS handshake protocol. One cell covers both without any wiring changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a ProSeries panel and confirmed the BMS accepted the charge cycle without fault codes. Voltage settled at 8.4V fully charged, within the panel's expected float range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation float charge window:\u003c\/strong\u003e\n    Do not trigger a zone test immediately after fitting this cell. The panel needs 24–48 hours on float charge before its BMS reports accurate battery status. Running a diagnostic test inside that window will likely produce a false low-battery fault.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm panel showing low battery hours after installing new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ProSeries panel reads battery state by monitoring float voltage — not by measuring raw cell capacity. A freshly installed Ni-MH cell sits below float threshold until the panel's internal charger brings it up, which typically takes 24–48 hours. During that window, the panel reports low battery because the voltage hasn't crossed the acceptance threshold yet. Leave the panel on mains power and wait the full 48 hours before assuming the cell is faulty.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm losing programming during a power outage after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the panel drops its programming when mains power fails, the new battery hasn't been accepted into the backup circuit yet. The ProSeries requires a full conditioning cycle — typically 48 hours on float — before the cell can sustain panel memory under load. A partially charged cell may deliver enough voltage to trigger the siren but not enough to hold the processor's memory register stable. Keep the panel on AC power for two full days after fitting the new cell before cutting mains to test backup operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309833060442,"sku":"BWCS-HYL500BT-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309833093210,"sku":"BWCS-HYL500BT-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309833125978,"sku":"BWCS-HYL500BT-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYL500BT-1.webp?v=1777868260","url":"https:\/\/batteryweb.com\/products\/resideo-proseries-replacement-battery-72v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
