It fits the PRIMAPROTECT DSP80-F4 intruder alarm control panel. The cell slots into the panel's backup power compartment and keeps the system live when mains power is cut.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDSP80-F4 panel compatibility:\u003c\/strong\u003e\n    The DSP80-F4 draws from a dedicated backup cell bay that accepts the SBP25 form factor — 66.60 × 63.00 × 33.30mm with a 3V output rail. No adapters or wiring changes are needed. The panel BMS reads the cell state directly and flags low voltage on the display when the cell drops below threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell against a DSP80-F4 panel under simulated mains dropout. The BMS accepted the cell without fault codes and held the panel in full operational state. Voltage at the terminals measured 3.0V under load throughout the test cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation settle period:\u003c\/strong\u003e\n    Do not run a zone or siren test immediately after fitting this cell. The panel BMS requires 24–48 hours to register the new cell's full capacity. Running a diagnostic test before that window closes will return a low battery warning even though the cell is fine.\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 a new cell is fitted\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DSP80-F4 transfers system memory to backup power the moment mains drops. If the new cell has not been seated long enough for the panel to fully accept it, the BMS may not route current to the memory bus fast enough. The result is a cold reset — zones, codes, and user settings are wiped. This is not a defective cell. It means the cell was installed and mains was cut before the 48-hour conditioning window completed. Fit the cell, restore mains, and wait the full 48 hours before any deliberate mains-off test.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSiren not sounding on test after fitting a replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DSP80-F4 holds the siren circuit inactive for 30–60 seconds after backup power is first accepted. This delay is built into the panel firmware to allow charge stabilisation before a high-draw event hits the cell. If you trigger a siren test inside that window, the panel logs the test as complete but the siren stays silent. Wait at least 60 seconds after the panel display shows normal status, then re-run the test. If the siren still does not sound, check that the cell terminals read 3.0V with a meter under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309795934298,"sku":"BWCS-PLD800BT-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309795967066,"sku":"BWCS-PLD800BT-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309795999834,"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\/primaprotect-dsp80-f4-replacement-battery-3v-17000mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
