It slots into the panel housing and keeps the alarm system active during mains power outages. Capacity matches the original 600-XTI-BAT specification at 15Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSimon XTi panel compatibility:\u003c\/strong\u003e\n    The Simon XTi, Simon XTi Control Panel, and Simon Xti variants all use the same 6V backup cell bay, connector pinout, and charge management circuit — this battery fits all three 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 the Simon XTi charge controller and confirmed the BMS accepted the battery, held float voltage correctly, and did not trip a low-battery fault after the standard 48-hour conditioning window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePanel diagnostic timing:\u003c\/strong\u003e\n    Do not run a zone or siren test immediately after fitting this battery. The Simon XTi reports low battery during diagnostics if the cell has not yet reached full float charge — allow 24 to 48 hours on mains power before triggering any test sequence.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Simon XTi shows low battery hours after a new cell is installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Simon XTi panel samples backup battery voltage at fixed intervals and compares it against an internal threshold. A fresh Ni-MH cell straight from storage sits below that threshold until the charge controller brings it up to full float. The panel is not faulty — it is reading an accurate voltage on an uncharged cell. Leave the panel on mains power for 48 hours and the low-battery indicator will clear on its own.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm loses programming during a power cut after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the panel drops its zone programming or user codes during an outage shortly after a battery swap, the backup cell had not yet been accepted by the charge controller. The Simon XTi requires the battery to hold a stable voltage above approximately 6.4V before it will draw from it during a mains failure. A cell installed less than 24 hours before the outage may not have reached that threshold. Restore mains power, allow a full 48-hour charge cycle, then confirm the panel holds programming through a brief mains disconnect test.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309833257050,"sku":"BWCS-GEX600BT-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309833289818,"sku":"BWCS-GEX600BT-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309833322586,"sku":"BWCS-GEX600BT-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GEX600BT-1.webp?v=1777868235","url":"https:\/\/batteryweb.com\/products\/ge-interlogix-simon-xti-wireless-control-panel-replacement-battery-6v-2500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
