It runs at 14.4V with a 14000mAh (201.6Wh) capacity. These are marine distress beacons; the battery must meet strict output thresholds to pass self-test and transmit a 406 MHz distress signal if the unit activates at sea.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEB-10, SEP-406, SEP-500, VEP8 fit group:\u003c\/strong\u003e\n    These four Saracom beacon models share the same battery housing dimensions, connector, and 14.4V supply requirement. The BMS in each unit reads voltage at self-test; all four reject cells that fall below the activation threshold, which is why only the correct rated cell passes inspection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We tested the 4ER34615M against the beacon's self-test cycle. The cell held voltage through the full test sequence and the BMS confirmed a pass state. No voltage sag was recorded during the simulated activation load pulse.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-replacement registration check:\u003c\/strong\u003e\n    After swapping the battery, verify your beacon's registration with your national maritime authority — COSPAS-SARSAT records tied to your 15-digit hex ID do not update automatically after maintenance. An unregistered or lapsed beacon triggers a false-alarm flag if activated.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Saracom EB-10 fails its self-test after the battery expiry date passes\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-SOCl2 cells lose capacity through internal self-discharge even when the beacon is never activated. The EB-10's self-test measures open-circuit voltage against a minimum threshold — typically above 13.5V under simulated load. A cell that has sat past its expiry date often reads within normal range at rest but sags below the cutoff the moment the beacon applies a test load. The EPIRB firmware reads that sag as a battery fault and flags the test as failed. Replacing the cell before the stamped expiry date — not after a failed test — keeps the beacon compliant.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWater ingress fault after battery compartment access\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe most common error after a battery swap is a failed waterproof seal. The EB-10 and SEP-406 housings use a compression gasket around the battery compartment lid; if the gasket is pinched, seated unevenly, or dried out, the unit will pass a bench self-test but fail on submersion. Inspect the gasket for flat spots or cracking before reassembly. Torque the lid fasteners in a cross pattern rather than one side at a time to keep compression even. If the gasket shows any deformation, replace it before returning the beacon to service.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381324939354,"sku":"BWCS-SEP406FM-1","price":108.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381324972122,"sku":"BWCS-SEP406FM-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381325004890,"sku":"BWCS-SEP406FM-3","price":142.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SEP406FM-1.webp?v=1778900030","url":"https:\/\/batteryweb.com\/products\/saracom-eb-10-replacement-battery-144v-14000mah-li-socl2","provider":"BatteryWeb","version":"1.0","type":"link"}
