GME warns against unauthorised EPIRB batteries

PERIODIC battery replacement is essential to maintaining the compliance of EPIRBS and PLBs beacons with applicable ANZ standards. These standards are produced in order to maximise the likelihood of the beacon functioning correctly in the adverse environments in which distress and emergencies generally arise.

Only the manufacturer or its authorised service centre has the necessary equipment, access to the factory approved parts and technical information to carry out battery replacement or repairs and then confirm that the beacon continues to meet the relevant standard.

Serious risks arise if batteries are replaced or repairs to beacons are undertaken by someone other than the manufacturer (or its authorised service centres).

In recent weeks it has come to GME’s attention that a number of non-certified beacon service centres are offering a low cost EPIRB and PLB battery replacement service.

Whilst such offers and operations are not technically breaking the law in replacing beacon batteries, they are certainly exposing themselves for liability particularly if the beacon owner is unaware they are non-compliant and the beacon may not function correctly in an emergency.

Australian/New Zealand standard 4280.1 (EPIRB) and 4280.2 (PLB) mandate that beacons must be returned to the manufacturer or a manufacturer’s approved service centre when repairs or battery replacement are required. This standard document is available from

Furthermore, if a beacon is required to meet carriage requirements under CASA or Maritime regulations the standard requires the beacon must be compliant with AS/NZ 4280.1 for EPIRBs or 4280.2 for PLBs. Consequently if the beacon battery was replaced or serviced by a non-certified service centre then the beacon is non-compliant for mandatory carriage requirements in Australia.

The Australian Maritime Safety Authority (AMSA) has provided further clarification and guidance on beacon maintenance.
