It powers emergency signalling equipment — EPIRBs, PLBs, and distress beacons — where power delivery under extreme conditions is non-negotiable. Li-MnO2 chemistry is the correct type for this application; do not substitute a different chemistry.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMarine safety device fit:\u003c\/strong\u003e\n    Simrad specifies the 82-1001A across its emergency beacon and flotation device range because Li-MnO2 holds voltage flat over a wide temperature range and tolerates long standby periods without significant capacity loss — both critical in saltwater emergency environments.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through activation load cycles and confirmed the BMS delivers stable voltage from cold start. Open-circuit voltage measured 9.1V and held within tolerance under simulated beacon transmission load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-replacement beacon registration:\u003c\/strong\u003e\n    After fitting a new battery, check whether your national maritime authority requires re-registration of the device. In many jurisdictions, EPIRB and PLB maintenance — including battery replacement — triggers a registration review. An unregistered beacon may fail a coastal inspection or, worse, not resolve to your vessel in a rescue.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMarine EPIRB not activating on battery self-test\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMost Simrad emergency beacons run an automatic self-test that checks battery voltage against a minimum activation threshold. If the installed battery has aged below that threshold — even if it was never used — the self-test will flag a fault. Li-MnO2 cells lose capacity slowly over time regardless of discharge cycles, which is why manufacturers assign a hard expiry date rather than a use-based replacement interval. If the self-test fails on a freshly installed 82-1001A, check that the battery contacts are clean and that open-circuit voltage reads at least 9.0V before assuming a device fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWater ingress after battery compartment access\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe waterproof seal on marine safety devices depends entirely on the gasket seating correctly every time the battery compartment is opened. A gasket that is pinched, displaced, or contaminated with salt residue will allow ingress at depth or in heavy spray — and the device will show no external sign of the fault until it fails in service. After fitting the 82-1001A, inspect the gasket visually before closing the housing, wipe the sealing surface with a clean dry cloth, and confirm the cover locks to its marked torque or click-close position. Run the self-test immediately after reassembly to confirm the device is operational.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381324185690,"sku":"BWCS-MRA500FM-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381324218458,"sku":"BWCS-MRA500FM-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381324251226,"sku":"BWCS-MRA500FM-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MRA500FM-1.webp?v=1778899987","url":"https:\/\/batteryweb.com\/products\/simrad-replacement-battery-9v-1350mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
