It fits the VESTA-111-NIMH, VESTA-112-NIMH, and VESTA-113-NIMH control units. The battery provides backup power to the panel and connected sensors when mains power is lost.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVESTA-111 \/ 112 \/ 113-NIMH compatibility:\u003c\/strong\u003e\n    All three panels run the same 7.2V backup rail and use the same connector and BMS handshake. A single cell covers the full model range without any wiring 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 through a full charge cycle on a VESTA-112-NIMH panel. The BMS accepted the cell without fault codes, completed float charging within 36 hours, and reported healthy status on the panel display.\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 fitting this cell. Allow 24 to 48 hours on float charge first. Running a diagnostic test on an uncharged replacement cell will trigger a false low-battery report from the panel.\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 a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eVesta hybrid panels read backup battery status through the BMS, not a direct voltage meter. A freshly installed Ni-MH cell sits below the BMS acceptance threshold until it completes its first full float charge cycle. The panel interprets this as a fault and flags low battery even on a brand-new cell. Leave the panel powered on mains for 24 to 48 hours without triggering any tests — the fault will clear once the cell reaches approximately 8.64V at full charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm losing stored programming during a power outage after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the panel drops its zone configuration or user codes during a mains outage shortly after a battery replacement, the new cell had not yet been accepted by the BMS. Until the first float charge cycle completes, the panel treats the battery as unavailable and draws no backup current from it. When mains drops, the panel loses power entirely and resets to factory state. Fit the replacement cell, restore mains power, and allow a full 48-hour conditioning period before testing or switching off the mains supply.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309820313690,"sku":"BWCS-VTA112BT-1","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309820346458,"sku":"BWCS-VTA112BT-2","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309820379226,"sku":"BWCS-VTA112BT-3","price":96.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VTA112BT-1.webp?v=1777868465","url":"https:\/\/batteryweb.com\/products\/vesta-hybrid-power-plants-replacement-battery-72v-4500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
