It fits models 0-100459, 0-100498, 0-100535, and 0-5466-8, among others. The battery provides backup power to keep wireless sensors and alarm components active when mains power is interrupted.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model fit — 0-100459, 0-100498, 0-100535, 0-5466-8:\u003c\/strong\u003e\n    These panels share the same 9.6V Ni-MH cell format, connector pinout, and charge management circuit. The BMS on each accepts this cell without modification or firmware 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 Visonic panel and confirmed the BMS completed a full charge cycle without fault codes. The cell held voltage within spec across the charge and rest phases, and the panel cleared its low-battery flag after the conditioning period.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install panel communication:\u003c\/strong\u003e\n    Do not run a zone or siren test immediately after swapping this cell. The panel's charge controller needs 24–48 hours at float charge before the battery status register reports accurately. Testing before that window often triggers 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\"\u003eAlarm panel losing programming during a power outage after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed Ni-MH cell does not immediately act as a conditioned backup. The panel's charge controller must first complete a full acceptance cycle — typically 48 hours on mains — before the battery can sustain panel memory during a blackout. If you replace the cell and a mains outage occurs within that window, the panel may lose zone programming and revert to default settings. Restore mains power, allow a full 48-hour charge cycle, then verify retained programming before the next scheduled test.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePanel showing tamper fault immediately after battery access\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eVisonic panels monitor the housing lid via a tamper switch that trips if the cover is not seated fully. After swapping the battery, if the lid or back cover is even slightly ajar, the panel logs a tamper fault and may trigger a local alert. Check that all housing clips are fully engaged and the cover sits flush before closing the app or control panel. A properly closed housing clears the tamper flag within 10–30 seconds without any panel reset required.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309833748570,"sku":"BWCS-VPX912BT-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309833781338,"sku":"BWCS-VPX912BT-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309833814106,"sku":"BWCS-VPX912BT-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VPX912BT-1.webp?v=1777868465","url":"https:\/\/batteryweb.com\/products\/visonic-0-100459-replacement-battery-96v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
