It fits the 710-16X, 710-21X, D14000, and over 85 compatible Daitem alarm control panels. The cell maintains backup power to the panel during mains failure so the system stays armed and monitored.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e710-16X and 710-21X panel compatibility:\u003c\/strong\u003e\n    These panels share the same BATLI02 battery bay, voltage rail, and connector pinout. The backup circuit draws from a single cell at 7.2V nominal, so any panel in this range accepts this cell without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Daitem control panel under simulated mains-off conditions. The BMS accepted the new cell, held the panel in backup mode without fault codes, and the panel returned to normal supervision once mains was restored.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation float charge window:\u003c\/strong\u003e\n    Do not run a zone test or trigger a diagnostic within the first 24–48 hours of installation. The panel charges the new cell via a float circuit, and the battery voltage needs to stabilise before the panel will report a clean battery status. Testing too early can generate a false low-battery event.\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 replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed BATLI02 cell is not at full charge when it leaves the warehouse. The panel's backup circuit needs 48 hours of float charging from the mains supply before the cell can sustain the panel memory and logic board through a full outage. If mains power drops before that window closes, the panel may lose zone assignments, user codes, or timing settings. Restore mains, allow the full 48-hour conditioning period, then confirm backup function with a short mains interruption test.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSiren not sounding on a test immediately after backup battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDaitem panels impose a charge-stabilisation delay before arming the siren output on a new backup cell. This is a deliberate firmware behaviour — the panel suppresses the siren trigger for roughly 30–60 seconds after the backup circuit first detects the new cell. If a test is run inside that window, the siren stays silent even though the panel shows armed. Wait at least two minutes after seating the new cell, confirm the panel shows no fault on the display, then run the siren test again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309781680218,"sku":"BWCS-BCT834BT-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309781712986,"sku":"BWCS-BCT834BT-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309781745754,"sku":"BWCS-BCT834BT-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BCT834BT-1.webp?v=1777868106","url":"https:\/\/batteryweb.com\/products\/daitem-710-16x-replacement-battery-72v-14500mah-li-socl2","provider":"BatteryWeb","version":"1.0","type":"link"}
