Rated at 17000mAh (51Wh), it holds the panel alive during mains power failure — keeping sensors active and alerts functional. It replaces OEM references SBP25 and 2-LR20 directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDSP-80 and DSP80-S5 compatibility:\u003c\/strong\u003e\n    Both panels run the same 3V backup battery circuit with identical connector and housing dimensions. The 2-LR20 cell format fits the battery compartment without modification, and the BMS reads voltage correctly across both panel firmware versions.\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 float-charge cycle on the DSP-80 panel. The BMS accepted the battery without fault flags, and voltage held steady at 3V through simulated mains cutoff events.\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. The DSP-80 panel requires 24 to 48 hours on float charge before its BMS reports a full battery state — testing before that window closes will trigger a false low-battery warning 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 zone programming during a power outage after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DSP-80 writes zone configuration to volatile memory that requires continuous backup voltage to retain. If the new cell is installed but the panel has not yet completed its 48-hour acceptance cycle, the BMS may not supply sufficient voltage when mains drops. The panel then resets to factory defaults mid-outage, wiping programmed zones, user codes, and entry\/exit timers. Give the new battery a full 48-hour float charge period on live mains before testing with a deliberate power cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSiren not sounding during a test immediately after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a charge-stabilisation delay, not a wiring fault. The DSP-80 panel suppresses siren output for 30 to 60 seconds after a new backup cell is detected, while the BMS confirms stable voltage delivery. Triggering a test alarm inside that window produces no siren response and can appear as a speaker or zone fault. Wait at least 60 seconds after the panel display shows normal status, then re-run the test — the siren should fire normally once the BMS confirms the cell is holding 3V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309795475546,"sku":"BWCS-PLD800BT-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309795508314,"sku":"BWCS-PLD800BT-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309795541082,"sku":"BWCS-PLD800BT-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PLD800BT-1.webp?v=1777868449","url":"https:\/\/batteryweb.com\/products\/first-innov-dsp-80-replacement-battery-3v-17000mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
