Replacing the Battery in Your PLB

10,334
Quick overview: PLB batteries typically last five to ten years, but only an authorised service centre can replace one, it's a compliance requirement under AS/NZS 4280.2, not just a manufacturer preference. This guide explains why opening the unit yourself risks compromising the seals and voiding compliance, what a proper service includes, and how to find the right contact for your beacon's brand, from ACR and GME to McMurdo and Ocean Signal, so your PLB is genuinely ready before you actually need it.

A PLB is a last line of defence in a genuine emergency. When you activate it, you need it to work. That reliability depends entirely on the battery inside, and batteries don’t last forever.

This guide covers what you need to know about PLB battery replacement in Australia: when to do it, why it must be done by an authorised centre, and where to get your specific device serviced.

Battery Shelf Life

PLB battery life varies by manufacturer and model, but is typically around five to ten years. The battery expiry or replacement date is marked on the beacon and should be checked before every trip. Once that date is reached, the battery can no longer be relied upon to sustain the beacon’s required distress transmission. A PLB that has been activated in an emergency should also be returned to the manufacturer or an authorised service centre for inspection and battery replacement before being relied upon again.

Don’t wait until the expiry date arrives. Arrange servicing at least a few months in advance, particularly before any major remote trip.

Why You Can’t Replace It Yourself

PLB batteries are not user-replaceable. This isn’t just a manufacturer recommendation, it’s a compliance requirement under Australian and New Zealand Standard AS/NZS 4280.2 for PLBs (and 4280.1 for EPIRBs).

Opening the unit yourself risks:

  • Compromising the waterproof seals that protect the electronics
  • Incorrect installation that causes the device to fail silently
  • Loss of compliance with carriage requirements under Commonwealth, State, or Territory law

The built-in self-test function on most PLBs does not verify full compliance. A beacon that passes its own test may still fail to transmit correctly in the field if it has been improperly serviced.

If your PLB is required by law to be carried, on a vessel or aircraft, for example, a non-compliant device doesn’t satisfy that requirement.

What Authorised Servicing Includes

When you send your PLB to the manufacturer or an approved service centre, the service typically covers:

  • Full device inspection for damage or degradation
  • New battery installation with a new manufacturer-specified expiry or replacement date
  • Replacement of waterproof seals and resealing
  • Hydrostatic pressure testing
  • Full function test and signal verification
  • Software update where applicable

The cost is modest relative to the purpose of the device.

Where to Get Your PLB Serviced in Australia

Servicing must be carried out by the manufacturer or their certified agent. Check the label on the side of your beacon for the brand, then use the contacts below.

If you’re unsure whether your servicing agent is authorised, contact the manufacturer directly before sending the device.

Check Your Expiry Date Now

The replacement date is on the beacon. If it’s within the next 12 months, start the process now. Turnaround times vary by manufacturer and can take a few weeks.

A PLB is a genuine last-resort safety device. Keeping it compliant and current is part of managing your equipment reliability before you need it.

    • Darren Bowman yeah I don’t know where to get them serviced sorry. There was a bit of a run on them because people thought they were an Aussie product. Turns out they were only assembled here. If I find out, I’ll let you know.

    • Darren Bowman a stab in the dark: try contacting RescueMe importer in Scoresby? to see if they can do it (also ACR). Consider that my RescueMe battery replacement cost me $180 a few years ago, so it’s a large % of the cost of a new PLB.

      • Richard Clarke I’ve included a list in the post of the only service centres in Australia authorised to replace batteries. Seems KTI is no longer supported for a battery replacement program. But agree either way your comment, it’s always worth a shot.
