It matches OEM part number 103-306545 and supplies standby power during mains outages to keep the panel active, sensors connected, and alerts functional. Capacity is rated at 11.1Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePowerMaster 360R backup rail:\u003c\/strong\u003e\n    The 360R uses a single Li-Polymer cell on a dedicated backup rail managed by the panel's onboard charge controller. The 3.7V nominal voltage and flat-pack form factor (67.50 × 63.60 × 5.00mm) must match exactly — the panel will reject cells with incorrect geometry or voltage profiles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the 360R's charge controller and confirmed the BMS accepted the cell without fault codes, held float charge correctly, and passed low-battery status clearance after a full conditioning period.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation charge window:\u003c\/strong\u003e\n    Do not run a zone or siren test immediately after swapping this cell. Allow 24–48 hours on mains power so the panel's charge controller can bring the cell to full float charge — triggering a diagnostic test before this window closes will cause the panel to report a false low-battery condition.\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 PowerMaster 360R does not report battery status based on a spot voltage reading at the moment of installation. The panel's charge controller samples voltage against an internal threshold that only clears once the cell has reached a sustained float charge level — typically after 24 to 48 hours on mains power. Installing a fully charged cell still triggers this delay because the controller needs to verify stable charge acceptance over time, not just an initial voltage. If the low-battery warning persists past 48 hours with mains power confirmed, check the connector seating and inspect for a loose cell contact.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePanel loses stored programming during a mains power cut after new battery install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf a mains outage occurs within the first 48 hours after a battery swap, the 360R may not draw sufficient backup current from the new cell to hold programming in volatile memory — the cell has not yet completed its initial charge acceptance cycle. The panel treats an insufficiently charged backup cell as absent and defaults to a safe-state reset, which can wipe zone configurations and user codes. To avoid this, keep the panel on mains power for at least 48 hours before deliberately testing a power-cut scenario. After that conditioning period, restore power and re-enter any lost codes at the keypad.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309827915866,"sku":"BWCS-VPX360BT-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309827948634,"sku":"BWCS-VPX360BT-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309827981402,"sku":"BWCS-VPX360BT-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VPX360BT-1.webp?v=1777868465","url":"https:\/\/batteryweb.com\/products\/visonic-powermaster-360r-replacement-battery-37v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
