AED lifespan: why replacement after 10 years is essential

An Automated External Defibrillator (AED) saves lives in the event of cardiac arrest. However, even this device doesn't last forever. The average lifespan of an AED is 8 to 10 years , after which replacement is strongly recommended. But why exactly is that limit set, and is it sometimes wiser to replace it sooner?

The technical lifespan of an AED

An AED contains sensitive electronics, capacitors, software, and sensors that are constantly ready to operate when needed. Due to the aging of components, even if the AED is rarely used, its reliability decreases over time.

After about 10 years, the risk of problems such as:

• Wearing electronic components .

• A capacitor that charges more slowly.

• Outdated software or resuscitation guidelines.

• Parts or electrodes that are no longer available.

• A model that has been declared 'End of Life' by the manufacturer.

An AED might still look good, but that doesn't mean it's completely safe and reliable . And that certainty is precisely what matters during resuscitation.

Why manufacturers keep it for 10 years

The 10-year period isn't arbitrary. Manufacturers base it on the expected lifespan of the electronic components and the long-term reliability of the AED. Capacitors, printed circuit boards, and batteries age naturally—even if the device is never used.

After about ten years, the manufacturer can no longer guarantee safety and functionality . Support also often ends: spare parts, electrodes, and batteries are no longer produced. Therefore, ten years is considered the maximum safe operating life of an AED.

There are also practical and financial considerations . Around the age of eight , the battery or another expensive component often needs to be replaced. In many cases, it's commercially more attractive to invest that money in a new AED with the latest life-saving technology. Modern models feature faster analysis algorithms, improved energy efficiency, and clear user guidance—all improvements that increase the chance of survival.

Safety first

An AED older than 10 years may still function , but that's not the same as being certain it works . In the event of a cardiac arrest, an AED must be 100% reliable. A dead battery, malfunction, or outdated software should never be the reason a life isn't saved.

That is why many organisations, companies and municipalities replace their AED before the tenth year , to ensure maximum reliability.

What can you do yourself?

• Check the production date on the back or in the manual of your AED.

• Note that date in your maintenance log .

• Plan for replacement around the 10th year – preferably sooner.

• Check if your model is still supported by the manufacturer.

Conclusion

The lifespan of an AED is a maximum of 10 years . After that, safety and reliability can no longer be fully guaranteed. Replacement is then the wisest option – not only technically, but also financially.

A new AED is an investment in certainty, safety and life-saving technology .
