The ACR GlobalFix V4 replacement battery is the genuine power pack for the GlobalFix V4 406 MHz beacon, and it's meant for boaters, commercial crews, and offshore anglers who need their distress beacon ready the day they leave the dock. A beacon is only as reliable as the cell inside it, and ACR Electronics builds this pack to the same standard as the original equipment. When your beacon's battery hits its service date, this is the part that brings it back to full readiness. We stock it for owners who maintain their own emergency gear and want a verified ACR component rather than a generic substitute.

This battery carries ACR Electronics part number 1104 and is built specifically for the GlobalFix V4 housing, so it seats and seals correctly without modification. The pack measures roughly 7 inches in length per manufacturer specifications and ships at about 1.2 pounds. Because a distress beacon transmits on 406 MHz to satellites and 121.5 MHz for local homing, the battery has to deliver consistent voltage across a long transmit cycle in cold water and rough conditions — a generic cell can't be trusted with that job. Replacing the pack also resets the beacon's service clock once the unit is properly tested. If you maintain a fleet, keep a spare on the shelf so a single expired battery never sidelines a vessel.
Plan the swap before your beacon's printed battery expiration date, not after, so you're never caught with a dead unit during inspection or an actual emergency. After installation the beacon should be checked through ACR's recommended self-test, and any reprogramming or registration updates handled through our beacon programming service. Owners who carry a ditch bag often refresh the battery at the same time they rotate other gear. Pair this part with the rest of your marine safety equipment and a fresh hydrostatic release unit to keep your float-free setup fully serviceable for another cycle.
This pack is built for the ACR GlobalFix V4 406 MHz beacon. It carries ACR Electronics part number 1104 and seats in the V4 housing without modification. It is not intended for other ACR models, so confirm your unit is the GlobalFix V4 before ordering.
Replace it on or before the expiration date printed on your beacon's battery label, typically tied to the manufacturer's stated service life. Don't wait until the date passes. A replacement done early keeps the unit ready for inspection and avoids leaving you with a dead beacon offshore.
Many owners handle the swap and self-test, but the beacon must pass its built-in self-test afterward and registration details should be confirmed. We offer a programming service that handles reprogramming and verification so the unit reports correctly to rescue authorities after the battery change.
Yes. This is the genuine ACR Electronics replacement battery, part number 1104, built to the original equipment standard for the GlobalFix V4. Using a verified ACR component ensures the pack delivers stable voltage through a full distress transmit cycle in cold, rough conditions.
