An AED can save a life in seconds, but only if it’s ready to use. It’s easy to think that once you’ve bought an AED, it’s good to go forever. The truth? AEDs have a lifespan, and so do the components that make them work.
If you’ve ever wondered how long your AED will last or when to replace batteries and electrode pads, you’re not alone. Here’s everything you should know to keep your device rescue ready.
How long does an AED last?
Most AED units last between 8 and 10 years before manufacturers recommend replacing them. That doesn’t mean it will suddenly stop working on its tenth birthday, but over time, technology changes, parts can wear out, and support for older models may end. Regular checks will help you know when it’s time for an upgrade.
Batteries and pads: they don’t last forever
AED batteries generally last 4 to 5 years, depending on the model and usage. Electrode pads have an even shorter lifespan usually 18 to 30 months. Because the adhesive gel can dry out or lose its effectiveness over time. Using expired pads can mean poor contact with the skin, which can reduce the chance of delivering a successful shock. That’s why it’s so important to keep track of expiration dates and replace parts before they’re past due.
What happens if you use expired components?
In an emergency, every second matters. Expired batteries might not have enough charge to power the AED, and expired pads may not stick properly, making the shock ineffective. It’s a risk you don’t want to take when someone’s life is on the line.
A quick checklist for AED readiness
- Check expiration dates on batteries and pads
- Make sure indicator lights show the unit is ready
- Keep your AED in a visible, accessible location
- Replace any used or expired components immediately
