Maintaining and inspecting an AED: Is your defibrillator ready to respond?

Sep 8, 2026

Having an automated external defibrillator (AED) in your business is already a good reflex. But that's not all.

An AED can remain unused for several months, sometimes even several years. During this time, its electrodes age, its battery approaches its end of life, and no one necessarily thinks to check if everything is still in order.

And when an emergency arises, it's certainly not the time to discover that a component needs to be replaced.

An AED must be checked

Even if AEDs are designed to perform self-checks, some elements still need to be monitored.

For example:

  • the expiration date of the electrodes;
  • the condition and lifespan of the battery;
  • the device's operating indicator;
  • the general condition of the AED;
  • its accessibility;
  • the presence of necessary accessories.

If certain components are approaching their replacement date, you can directly consult our AED electrodes and accessories as well as our replacement batteries.

Electrodes and battery: two dates not to forget

The electrodes of an AED are not good indefinitely. They have an expiration date and must be replaced according to the manufacturer's recommendations.

The same applies to the battery, whose lifespan varies from one model to another.

The problem is that these deadlines are easy to forget, especially in an organization where no one is officially responsible for the AED.

Do you know who takes care of your AED?

It's a simple question, but the answer is not always clear.

Who checks the device? Who monitors expiration dates? Who ensures that the AED is always in the right place?

If you have several devices or several establishments, monitoring can quickly become more complicated.

The important thing is to have a clear view of:

  • the location of each AED;
  • replacement dates for electrodes and batteries;
  • the person responsible for monitoring;
  • the last check performed.

DefibSync to simplify monitoring

It is precisely to facilitate this management that Cardio Choc developed DefibSync.

The platform allows you to group information related to your defibrillators and better monitor your devices and their main deadlines.

If you manage one or more AEDs, you can discover DefibSync and its functionalities to centralize the monitoring of your devices.

What if your AED hasn't been checked in a while?

Cardio Choc also offers an AED inspection service directly at your facilities, throughout Quebec and in the Ottawa region.

Our team can check the condition of the device, electrodes, battery, accessories, accessibility, and signage, then provide you with their findings and recommendations.

You can learn more about our AED inspection and maintenance service or make a request directly online.

Whether you have a single AED or several devices distributed across different sites, the goal remains the same: to ensure they are ready when you need them.

On World First Aid Day, it might just be the right time to ask yourself:

When was your AED last checked?
