The Importance of Keeping AEDs Up to Date: Why Regular Checks Save Lives

September 5th, 2025

Automated External Defibrillators (AEDs) are essential life-saving tools designed to restore a normal heart rhythm during sudden cardiac arrest (SCA). They’re commonly found in schools, healthcare facilities, workplaces, and public spaces, and for good reason. When every second counts, having a functioning AED can make the difference between life and death.

But having an AED on-site isn’t enough. To ensure it’s ready when you need it, routine maintenance and regular checks for expired parts are critical. AEDs are designed to be easy to use, but they’re still sophisticated medical devices that require periodic attention to remain reliable.

In this blog, we’ll explore why AED maintenance matters, the risks of expired pads and batteries, and best practices for keeping your device ready to save lives.

Why AED Maintenance Matters

Sudden cardiac arrest can happen anywhere, at any time, and to anyone, even seemingly healthy individuals. According to the American Heart Association, over 350,000 out-of-hospital cardiac arrests occur in the U.S. each year, and survival depends heavily on rapid response.

An AED in good working condition is one of the most effective tools for increasing survival rates. However, if your device isn’t functioning properly, whether due to expired pads, depleted batteries, or lack of testing, it could fail when you need it most.

Key reasons why AED upkeep is essential:

Readiness Saves Time: Seconds matter during cardiac emergencies. Regular checks ensure your AED works instantly when needed.
Compliance with Safety Standards: Many workplaces, schools, and public institutions must follow specific AED maintenance requirements to stay compliant with federal, state, or industry guidelines.
Liability Protection: Maintaining an AED demonstrates due diligence and reduces legal risks if an incident occurs.
Peace of Mind: Properly maintained AEDs give staff, students, and visitors confidence that they’re protected in an emergency.

Understanding AED Expiration Dates

Many people are surprised to learn that AEDs have components that expire, including electrode pads and batteries. While the AED unit itself can last years, these consumable parts must be replaced periodically to ensure the device works correctly.

Electrode Pads

Contain a special gel that dries out over time, reducing their ability to deliver shocks effectively.
Typically expire every 18 to 36 months, depending on the manufacturer.
Expired pads may fail to adhere properly, delaying life-saving treatment.

Batteries

Most AED batteries last between 2 to 5 years, depending on usage and model.
An expired or low-power battery can prevent the AED from powering up during a crisis.
Some AEDs self-test regularly, but visual inspections are still essential to ensure battery readiness.

Risks of Neglecting AED Maintenance

Failing to monitor AED expiration dates or perform regular checks can have serious consequences:

Device Failure During Emergencies – An expired battery or faulty pads can render the AED useless when time is critical.
Increased Response Time – If an AED malfunctions, precious minutes are lost finding a backup solution.
Legal and Compliance Issues – Many states have laws requiring AED upkeep; failing to comply can result in fines or liability concerns.
Loss of Trust – If your organization can’t respond effectively to an emergency, it impacts your reputation and confidence among employees, students, and visitors.

Best Practices for AED Readiness

Implementing a structured AED maintenance plan ensures your device remains reliable year-round. Here are six key best practices for decision-makers across schools, workplaces, and public facilities:

1. Schedule Monthly Inspections

Inspect your AED monthly to confirm:
- The status indicator shows the device is operational
- Pads and batteries are within expiration dates
- The device is stored properly and accessible at all times

2. Keep a Maintenance Log

Maintain a detailed record of AED checks, including dates, results, and any replacements. This documentation can be valuable for audits, inspections, and liability protection.

3. Replace Expired Components Promptly

Order replacement pads and batteries ahead of time so your AED never becomes inactive due to expired parts.

4. Train Your Team

Even the most reliable AED is only effective when staff know how to use it. Provide training sessions and refreshers on how to operate the device during emergencies.

5. Set Automated Reminders

Use digital tools or calendar alerts to track expiration dates and testing schedules, ensuring nothing slips through the cracks.

AEDs in Schools, Workplaces, and Public Safety

AED readiness is especially critical in environments where large groups of people gather, such as schools, workplaces, and public spaces.

Schools & Universities: Protect students, athletes, and staff by ensuring AEDs are maintained and accessible at gyms, cafeterias, and sports fields.
Workplaces: OSHA strongly encourages AED programs in high-density facilities to safeguard employees and visitors.
Public Safety & Government Buildings: Rapid response saves lives in high-traffic environments, making AED readiness essential for first responders and the public alike.

By keeping AEDs up to date and maintaining proper emergency protocols, organizations not only comply with safety requirements but also demonstrate a strong commitment to protecting lives.

A Culture of Preparedness Saves Lives

An AED is only effective if it works when you need it. Regular maintenance and monitoring of expiration dates ensure your team is ready to act confidently in any emergency. Whether you manage a school, healthcare facility, workplace, or public safety department, keeping your AED program up to date is one of the simplest and most impactful steps you can take to protect the people who depend on you.
