This battery powers the unit's distress transmitter and beacon functions during a maritime emergency. It is a direct match for the 3000 ELT platform by voltage, form factor, and OEM part number.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e3000 ELT platform fit:\u003c\/strong\u003e\n    The Merl Pointer 3000 ELT uses a sealed battery compartment with a specific footprint — 67.20 x 64.50 x 61.40mm. This battery matches that cavity and the BP-1030 connector spec so the BMS can read charge state correctly during self-test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery against the 3000 ELT self-test sequence. The BMS handshake completed, the activation threshold was met, and the self-test LED pattern cleared without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-replacement compliance check:\u003c\/strong\u003e\n    After fitting a new battery, update the battery expiry date on your vessel's safety log and verify the new expiry is visible on the unit label — maritime inspectors check both the physical date stamp and the vessel record during safety audits.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 3000 ELT fails its self-test even with a new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 3000 ELT self-test checks more than voltage — it verifies the BMS can read a valid battery state and that the transmitter circuit reaches activation threshold. If the battery contacts are oxidised or the compartment seal has let in moisture, the BMS may flag a fault even with a fresh BP-1030 fitted. Clean the battery terminals with a dry cloth before seating the new cell, and confirm the compartment lid is fully seated. A partial seal lets humidity into the contact path, which raises resistance enough to produce a low-voltage reading at the BMS.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery expiry date showing as past on a unit that's never been activated\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAlkaline cells in standby devices lose capacity through self-discharge even without any load — the Merl Pointer 3000 ELT is no exception. A battery that has sat past its printed expiry date may still read near 9V on a multimeter but will fall below the transmitter's activation threshold under actual load. Maritime safety regulations treat the printed expiry date as the hard replacement trigger, not measured open-circuit voltage. Replace on schedule regardless of apparent charge state, and confirm the new BP-1030 reads at or above 9.0V under a brief load check before closing the compartment.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381323858010,"sku":"BWCS-MBP300FM-1","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381323890778,"sku":"BWCS-MBP300FM-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381323923546,"sku":"BWCS-MBP300FM-3","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MBP300FM-1.webp?v=1778899987","url":"https:\/\/batteryweb.com\/products\/merl-pointer-3000-elt-emergency-locator-replacement-battery-9v-3840mah-alkaline","provider":"BatteryWeb","version":"1.0","type":"link"}
