Understanding AED Maintenance for Better Performance

AED maintenance is one of those tasks that can feel easy to postpone, especially if your unit hasn’t been used. But when someone needs help, there’s no time for second guesses or slow starts. That’s why regular upkeep is worth doing. It makes sure your device is ready when it’s needed most.

We're right in the middle of the Australian summer, and that brings some extra things to keep in mind. Heat and humidity can affect how well an AED works and how long the parts last. Caring for your equipment through the warmer months can prevent simple issues from becoming big problems. Here are some reminders to help keep your unit in working order all year round.

Why Regular AED Checks Matter

Just because your AED hasn’t needed to step in doesn’t mean it’s problem-free. When left unchecked, parts can wear out or stop working without showing any clear signs. Batteries can drain, pads can expire, and sometimes connections loosen over time.

• Monthly checks are a simple habit that can keep your unit in working shape

• Internal faults can go unnoticed if no one resets or tests the unit once in a while

• A visual inspection is often enough to catch common signs of trouble early

Staying ahead of these issues doesn’t take long. Five minutes a month might be all it takes to know that everything’s good to go, just in case someone nearby calls out for help.

What to Look for During Routine Maintenance

A quick monthly check should turn up anything odd or out of place. You don’t need to take it apart or test beyond what’s built into the unit.

• Start with the indicator light. If it’s flashing green, all good. If it’s red or off, that’s a warning

• Check the expiry dates on both the pads and the battery. If they’ve passed their date or are close to it, it’s time to replace them

• Look over the full unit for dust, water spots, or worn cables

Pads need to be sealed and stored correctly, and the unit itself should be in a clean space, free from dirt or direct sunlight. Don't forget to keep it easy to reach. In an emergency, the last thing you want is trouble finding the device.

When performing your check, gently wipe off dust or fingerprints from the unit’s surface if you see them. Make sure the pads are still sealed in their original packaging and that there is no moisture damage inside the storage case. Batteries should sit snugly, without looseness or rattling. Every small bit of care keeps the AED ready for action, especially after a busy day or event at home or in the community.

How Heat and Summer Weather Affect AEDs

Australian summers aren’t gentle on electronics. High temperatures and humidity can drain batteries and damage sealed parts like pads and internal wiring. If your unit sits in a hot vehicle or near a window all day, there's a good chance its parts won't last as long as expected.

• Store your AED inside where the temperature stays steady

• Keep it out of direct sunlight and away from any heat sources

• Don’t leave it in the boot while parked for long periods

Battery life can drop faster when exposed to heat, and sticky or swollen pads are signs that moisture is getting in. It’s better to move the device indoors between uses than risk it not working when you need it most.

Summers can also bring storms, so if your area is prone to power cuts or flooding, store your AED above floor level. If you travel with your unit, for example, going camping or to community events, cooler bags or insulated pouches can slow down wear from sudden heat spikes. With a little planning, you can avoid most trouble caused by the warmer months.

Knowing When to Replace AED Pads or Batteries

AED pads and batteries don’t last forever, even if the unit never gets turned on. Each one has an expiry date printed on the packaging, but use your eyes too. Damaged, discoloured, or open packaging means it’s time for a fresh set.

Keep an eye out for:

• Pads that feel stiff, dry, or no longer sealed

• Batteries that show signs of leaking or swelling

• Any message on the device saying parts need to be changed

Even if a pad or battery looks fine, it's worth replacing once it's expired. A well-timed replacement is always better than a risky guess. You don’t want to realise it’s past due when you're already helping someone in need.

Most common AEDs in Australia use brand-specific pads and batteries that suit both public access and workplace environments. At Restart the Heart, we supply compatible parts for models such as Heartsine, Philips, and Zoll, so it’s easy to find what matches your device. You should always select replacements specifically recommended for your AED, as mixing brands or using incorrect parts risks device failure.

Getting into a routine helps avoid letting dates slip by. Try linking pad and battery checks to another monthly task, like paying bills or checking smoke alarms. This way, you won’t forget, and your device will always have the best chance of working properly, even if it sits unused for years between emergencies.

Keeping AED Records Simple and Useful

Keeping track of your checks doesn’t have to be a chore. A hand-written date on a wall calendar or a reminder set on your phone can work just fine. If others share the responsibility of maintaining the unit, keep a shared notebook nearby with dates and what was checked.

• Write down when you inspect the AED and what you checked

• Note when the next pad or battery is due for replacement

• Keep it somewhere that won’t go missing or get thrown away

Over time, this becomes a quick way to make sure nothing slips through the cracks. Well-kept records also help if someone new takes over maintenance or if an incident has to be reviewed later.

Even a straightforward chart or simple checklist can be helpful. Record the battery level, pad expiry, and anything unusual you notice. Some units may beep if there’s an issue, but it’s always safer to have a written backup. This prevents confusion if you’re away from home, if someone else needs to check the AED, or during an emergency. Shared responsibility also makes it easier to stay on top of routines year-round.

Reliable AED Maintenance Means Confidence

Taking simple steps to keep your AED in top shape can make a big difference later. Regular checks, safe storage, and knowing what to expect from each part create a sense of calm when something unexpected happens. Getting familiar with your unit means no panic if it’s ever needed.

By taking care of maintenance along the way, you give your AED the best chance to do its job without delay. And when help is on the way, every second counts. A device that’s looked after properly is more likely to work the way it should, quickly and without second-guessing.
