The ACR Electronics 2875.91 battery replacement service restores a Satellite3 406 emergency beacon to ready status with a fresh power source and a complete bench check. ACR beacon batteries carry a five-year service life, so when that interval comes up, the unit has to go back for a factory-grade refresh rather than a field swap. This service covers commercial fishermen, offshore cruisers, and anyone running waters where a working distress beacon is the difference-maker. You send in the beacon, and it comes back sealed, tested, and documented. It belongs in the same maintenance rotation as the rest of your emergency beacons.
The service installs a 1102 five-year lithium battery and includes the parts, labor, and a test verification report. Technicians run a full physical integrity check, a pressure test, and a data transmission test to confirm the beacon still broadcasts correctly on the 406 MHz distress frequency. The seal and o-rings get replaced so the housing holds its waterproof rating after reassembly, and the spent battery is disposed of properly. Turnaround runs roughly three days from receipt when all components are in stock. The shipped package measures about 4 inches long by 3 inches wide by 1 inch high and weighs 0.8 pounds. This is a return-to-service program, not a loose battery pack, which is why the transmission test and seal replacement are part of every job.
Schedule this service as your five-year mark approaches, before the beacon expires and leaves you without a registered distress signal on the water. Offshore operators and delivery captains typically tie the battery interval to their annual safety inspection so nothing slips. Once the beacon returns tested and resealed, it slots back into your ditch bag or bracket and is good for another five years. If you also run a handheld unit, look at our personal locator beacons and the broader beacon service options to keep your full safety kit current.
It includes a new 1102 five-year lithium battery, all required parts, and labor. Technicians perform a physical integrity check, pressure test, and data transmission test, replace the seal and o-rings, install the new battery, dispose of the old one, and return a test verification report with the unit.
ACR Electronics specifies a five-year battery service life. Replacing the battery on that schedule keeps the beacon ready to transmit a distress signal when needed. Tie the interval to your annual safety inspection so the expiration date never catches you off guard on the water.
Turnaround runs about three days from receipt when all components are in stock. You ship the beacon in, the work is completed and documented, and the unit is returned sealed and tested for another five-year cycle.
This service is matched to the ACR Satellite3 406 emergency beacon. If you run a different model, check our service options to confirm the correct battery program for your specific unit before sending anything in.
No. These beacons are sealed pressure-tested units, and the battery swap requires seal and o-ring replacement plus a transmission test to confirm the unit still broadcasts correctly. That is why it returns to a factory-authorized bench rather than getting opened on the boat.
