AED Maintenance Checks: How Often Is Enough?

AED maintenance is one of those jobs that’s easy to forget about until something goes wrong. The device sits there, quiet and still, and it's tempting to think it's ready to go when needed. But just like the batteries in a smoke alarm or the tyres on a work ute, AEDs need regular checks. A few minutes once a month can make a difference between smooth use and a nasty surprise.

Knowing what to look for and when to look for it makes everything easier. There’s no stress, no second-guessing. Just a steady habit that keeps things in order. When an emergency happens, we don’t want to be messing around with expired pads or dead batteries. We want that defib to work properly the first time.

Why Consistent Checks Matter Year-Round

AEDs mostly sit idle. That’s their job. But even unused, the parts inside don’t last forever. Batteries lose charge over time, even while just sitting there. Pads are sealed, but those seals can break down or lose effectiveness. And let’s be honest, a missed warning beep can go unnoticed for months if no one’s checking.

Leaving things unchecked doesn’t just put the device at risk. It slows everything down in a situation where time matters most. If a pad won’t stick properly or a battery runs flat at the wrong moment, it takes precious seconds we can't afford.

Here’s why those monthly checks make a real difference:

• Batteries and pads have expiry dates, even if they’ve never been used
  
• Devices can show warning signals that get missed without a visual check
  
• Dust, damp, or temperature changes can impact performance if left unnoticed

Restart the Heart provides pads and batteries for all leading AEDs, like Lifepak, HeartSine, Philips, and Defibtech, with expiry and model information featured on every listing for easier tracking.

What to Look at During a Monthly Check

A quick once-over doesn’t take long, but it needs consistency. We make sure our checks include the simple things that are easy to overlook.

• Check the battery indicator, most units have a light or screen that will show if something’s not right
  
• Check the expiry date on the pads, and confirm backups are in date too
  
• Look at the casing, any cracks, exposed wires, or signs of wear need attention
  
• Make sure the area around the AED is tidy and clear, not blocked or tucked behind other gear

If we spot anything odd during these checks, we note it right away. Sometimes it’s as simple as replacing expired pads. Other times, it's worth getting a trained tech to inspect the unit more closely.

Restart the Heart’s support and FAQ sections outline the basics for pad and battery checks, including visuals for expiry dates and safe storage.

How to Adjust Checks for Winter and Early Spring

Late winter and early spring can be tough on gear, even indoors. Colder air can weaken battery strength, and condensation can creep in unnoticed. Around this time, we double up on a few things to prevent damage from the season.

• Move units out of damp or unheated spots like garages, sheds, or outdoor utes
  
• Avoid leaving the AED on icy surfaces that might lead to internal condensation
  
• Wipe down the housing if it feels cold or wet to the touch
  
• Listen for any error beeps or alerts that might be muffled by colder air or enclosed spaces

We’ve seen issues pop up in July with no warning signs leading up to it. One frost-heavy morning and suddenly a battery that seemed fine won't power the AED. That’s why this part of the year makes our checklists that little bit more detailed.

When to Replace, Not Just Check

There’s a difference between looking something over and making the call to replace it. We try not to hang onto parts that are on their last legs.

• If a battery is showing it’s low, don’t wait it out, swapping early is safer than hoping for the best
  
• Pads should never be kept past their expiry date, and should be replaced after any use, even if unused during a call-out
  
• If we’re not confident about the condition of something, especially in an older AED, we plan for a professional to take a closer look

The idea is to stay ahead. Replacing something too soon is almost always better than facing a failure during an emergency.

Set a Routine That Works for Your Setup

Every workplace or community hall is different. Some have busy rosters or rotating rosters, while others shut completely during breaks. No matter the setup, we’ve found that tying AED maintenance to ongoing routines works best.

• Set monthly calendar reminders or link the check to an existing practice, like your fire extinguisher check
  
• In schools or public venues, include the AED in monthly visual safety walkarounds
  
• Use a clear, printed checklist stored near the unit where each visit can be signed off
  
• Make space for a yearly deep check, especially before long closures or seasonal changes

Things can get missed easily during holidays or when roles change, so keeping records helps us stay on top of it. It also makes the job easier for whoever does it next.

A Ready Setup Means Less Panic, More Action

We’ve seen how a well-maintained AED leads to more confident use. People worry less about “doing it right” when the tools are ready and working. That peace of mind spreads across teams too.

The small habit of checking the AED once a month takes away the unknowns. It means we know where it is, know that it’s working, and trust that it will hold up when we need it. That’s the kind of setup we want, to step in fast without guessing, and to know that everything we rely on is exactly where it should be.

At Restart the Heart, we know that regular checks make all the difference in keeping your defib ready when life is unpredictable.
