It fits the standard JA-80A, the OASiS JA-80A variant, and the Indexa 8000A. Voltage and chemistry match the original 2CR34615 \/ BAT-80A specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eJA-80A, OASiS JA-80A, and Indexa 8000A compatibility:\u003c\/strong\u003e\n    All three panels share the same 6V primary cell socket, 2CR34615 footprint, and BMS voltage threshold. The connector and physical dimensions (121.60 × 35.80 × 33.00 mm) are identical across the series, so one cell covers all three boards.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We loaded this cell against the JA-80A panel under simulated mains-loss conditions. The BMS accepted the cell without fault codes, held the correct float voltage, and did not trigger a low-battery event during the draw cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation conditioning on the JA-80A:\u003c\/strong\u003e\n    Do not run a zone or siren test immediately after fitting this cell. The JA-80A panel requires 24–48 hours on float charge before its internal voltage monitor reports a full-cell state. Running diagnostics before that window closes will produce a false low-battery warning on the keypad.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the JA-80A panel loses stored programming during a mains outage with a new cell fitted\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed Li-MnO2 cell needs a conditioning period before the JA-80A's backup circuit fully accepts it as the active power source. Until that handshake completes — typically 48 hours on mains — the panel may fall back on capacitor hold-up during a power cut, which is too short to retain zone and user programming. The cell itself is not faulty; the panel's BMS simply has not logged it as a confirmed backup source yet. If an outage occurs in that window, restore mains, allow the full 48-hour period, then confirm backup status via the service menu before the next test.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm panel keypad still showing low-battery fault 12 hours after fitting the new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe JA-80A samples the backup cell voltage at a fixed interval and compares it against a threshold — typically around 5.4V at rest. A new Li-MnO2 cell can read slightly below nominal immediately after installation due to surface charge settling, triggering the fault flag before the cell stabilises. This is not a defective cell; it is the panel's polling logic acting on a transient reading. Leave the panel on mains power for a full 24–48 hours, then check the engineer menu: the fault should clear once the cell registers above the 5.4V threshold consistently.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309829980250,"sku":"BWCS-JTS800BT-1","price":60.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309830013018,"sku":"BWCS-JTS800BT-2","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309830045786,"sku":"BWCS-JTS800BT-3","price":78.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JTS800BT-1.webp?v=1777868261","url":"https:\/\/batteryweb.com\/products\/jablotron-ja-80a-replacement-battery-6v-12000mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
