When Should You Replace Your AED? Lifespan, Signs, and Safety Upgrades

AEDs are built to save lives—but like all life-saving tools, they don’t last forever.

If your automated external defibrillator is several years old, or you’ve never updated its parts, you might be putting safety at risk without even knowing it.

Whether you’re using a ZOLL AED Plus, Powerheart G5 AED, Philips HeartStart FRx, or any other trusted model, this guide will help you understand:

• When and why an AED should be replaced
  

• Warning signs your current device may be outdated or unsafe
  

• How AED technology has evolved in recent years
  

• Where to find the best AED defibrillators for sale today
  

Let’s explore everything you need to know to protect your workplace, school, gym, church—or even your home—with an AED that’s truly ready to respond.

🕑 How Long Does an AED Last?

Most AED defibrillators are designed to last 8 to 10 years, depending on the model and how well it’s maintained. But even if the unit appears in good condition, it may still fall behind in performance, compliance, or reliability as technology advances.

Here’s a general breakdown of device lifespans by brand:

• ZOLL AED Plus: 7–10 years
  

• ZOLL AED 3: 8+ years with Wi-Fi connectivity updates
  

• Powerheart G5 AED: 7–10 years
  

• Philips HeartStart FRx: Around 8 years
  

• Physio-Control LIFEPAK series: 5–8 years depending on the model
  

If your AED is reaching the 7-year mark or older, it’s time to review your options.

🚨 Signs It’s Time to Replace Your AED

Not sure whether you need a new AED or just a few replacement parts? Here are red flags to watch for:

1. Expired Battery or Pads That Are No Longer Available

Even if your AED still powers on, outdated or discontinued pads/batteries can make it unusable in an emergency. Check the expiration dates—and if replacements aren’t available for your model, it’s time to buy an AED that supports current accessories.

2. Inconsistent Self-Test Indicators

Most AEDs run automatic daily or weekly tests. If your device shows a red light or error message and fails multiple tests—even after replacing components—it may be at the end of its life.

3. Outdated Technology

Modern AEDs now feature:

• Real-time CPR feedback
  

• Pediatric mode or dual-pads
  

• Wi-Fi connectivity and data tracking
  

• Multilingual support
  

• More intuitive user interfaces
  

If your AED lacks these, upgrading to a model like the ZOLL AED 3, Philips HeartStart, or Powerheart G5 can make a major difference in usability and accuracy.

4. No Manufacturer Support

If the brand no longer services your model or sells replacement parts, it’s time to move on.

5. Physical Damage or Missing Components

Cracks in the casing, unresponsive buttons, missing signage or wall mounts—these are all liabilities during an actual emergency.

⚙️ AED Defibrillator Cost: What to Expect When Upgrading

Many organizations delay upgrades due to concerns about price, but the reality is: AED defibrillator cost has become far more affordable.

📍 AEDs by Location: Replacement Timelines

Depending on where your AED is located, replacement urgency may vary:

🏫 Schools & Daycares

Compliance and liability are top concerns. Upgrade every 7–8 years or sooner to models like the ZOLL AED Plus or Philips HeartStart FRx, which are pediatric-friendly.

🏋️♂️ Gyms & Fitness Centers

In Gyms, heavy usage, sweat, and equipment vibrations increase wear. Models like the Powerheart G5 or ZOLL AED 3 are ideal for durability.

⛪ Churches & Community Centers

Even with low usage, don’t rely on aging devices. A budget-friendly but updated model like the HeartSine Samaritan PAD 350P works well in these settings.

🏠 Homes

If you purchased an AED 8–10 years ago, it's likely due for a full upgrade. Home-friendly models like the Philips HeartStart are compact, intuitive, and easy to maintain.

📦 When Replacing an AED, Don’t Forget:

• Wall Cabinets and Signage – Use this opportunity to refresh visibility
  

• Pads & Batteries – Ensure your new model comes with fresh components
  

• Training Materials – Upgrade manuals, AED posters, and CPR guides
  

• Device Registration – Register your AED with the manufacturer for support and recall alerts
