ACR FBRS 2874 Battery Replacement Service f/Satellite3 406™

The ACR FBRS 2874 Battery Replacement Service for Satellite3 406™ is an essential maintenance item for serious mariners who depend on reliable emergency communications. If you've been on the water long enough, you know that a personal locator beacon (PLB) or emergency position-indicating radio beacon (EPIRB) is not a luxury—it's your lifeline. The Satellite3 406™ is one of the most trusted emergency signaling devices in recreational and commercial boating, and keeping its battery fresh ensures your distress call will be heard when it matters most.

This battery replacement service restores full operational capacity to your Satellite3 406™ unit, ensuring the beacon meets current Coast Guard and international maritime safety standards. ACR Electronics, the manufacturer, designs this service to replace the primary battery pack that powers the 406 MHz emergency transmission—the frequency monitored globally by search and rescue authorities. By opting for this official replacement service rather than attempting field repairs, you maintain the device's certification and warranty integrity while guaranteeing maximum transmission range and signal strength when deployed.

Boaters who fish offshore, cruise extended distances, or operate in remote waters should schedule this service every few years or per manufacturer recommendations—especially if the beacon has been activated or exposed to salt spray and humidity. Whether you're a commercial fisherman, charter boat operator, or recreational cruiser who takes extended blue-water passages, this replacement service keeps your emergency backup in peak condition. The compact 3 x 1 x 4 inch service unit is straightforward to arrange through authorized ACR distributors and typically involves sending your Satellite3 406™ for professional battery replacement and recalibration.
