How to Replace Expired AED Pads in Your Workplace

An AED can be mounted in plain sight, pass its self-test, and still be unprepared for a rescue if its electrode pads are past their use-by date. When you replace expired AED pads, you are protecting the part of the system that must make direct contact with a person’s chest during sudden cardiac arrest. For workplaces, schools, healthcare settings, and public facilities, this is a small maintenance task with life-saving consequences.

AED pads are not permanent accessories. Their conductive gel, adhesive seal, and sterile packaging are designed to perform within a defined timeframe. A pad set that looks unopened may no longer meet the manufacturer’s performance specifications after expiration. Readiness means checking the whole AED package - device, pads, battery, signage, trained responders, and records - before an emergency tests it.

Why AED Pads Have Expiration Dates

AED electrode pads contain conductive gel that helps the device analyze the heart’s rhythm and, when advised, deliver a shock through the chest. Over time, that gel can dry out or degrade. The adhesive may also become less reliable, making it harder to establish proper contact when seconds matter.

The sealed pouch protects the pads from air, moisture, and contamination, but it does not stop aging indefinitely. Manufacturers assign expiration dates based on testing of the pad materials and packaging. Using pads beyond that date introduces unnecessary uncertainty during a cardiac emergency.

The AED itself may still power on with expired pads attached. Some models will issue a visual or audible maintenance alert; others may display an accessory warning during routine checks. Do not rely on the absence of an alert as proof that your pads are current. Your documented inspection process should catch dates before a device signals a problem.

How to Replace Expired AED Pads Correctly

Replacing AED pads is usually straightforward, but the details depend on the AED manufacturer and model. Use replacement pads specifically approved for your device. Pads are not universally interchangeable, even when connectors appear similar.

First, confirm the AED model and the type of pads installed. Most organizations need adult pads, while some locations also need pediatric pads or a pediatric rescue setting. Schools, childcare programs, family recreation facilities, and organizations that serve children should assess their pediatric readiness based on their population, risk assessment, local requirements, and medical oversight.

Locate the expiration date on the pad package. It may be labeled as an expiration date, use-by date, or install-by date. If your AED is in a wall cabinet or carrying case, inspect the pads without damaging the sealed package. If the date has passed, remove the old pad cartridge or pad set according to the manufacturer’s instructions.

Install the new, compatible pads with the package intact. Many AEDs are designed to keep pads preconnected so the unit is ready to guide a responder immediately. Route and store the cable exactly as directed by the manufacturer so it will not snag, pinch, or prevent the cabinet or case from closing. Then verify the device’s status indicator or perform the prescribed readiness check.

Do not open a new pad package simply to inspect the pads inside. Opening the pouch can compromise the seal and shorten the usable life of the accessory. Confirm the date from the outside label, record it, and leave the new pads sealed until they are needed.

Inspect the Battery at the Same Time

A pad replacement is an ideal time to inspect the AED battery, but do not assume the battery needs replacement just because the pads do. Batteries and pad sets often have different service lives. Check the battery expiration or install-by date, the AED’s readiness indicator, and your maintenance record.

If both components are approaching expiration, replacing them during one service visit can simplify scheduling and reduce the chance of a future lapse. For multi-site organizations, standardizing replacement intervals can also reduce administrative burden. The right schedule still depends on each manufacturer’s instructions and the accessories installed in each device.

Build Pad Expiration Checks Into Your AED Program

The best time to find expired AED pads is not after an incident. Assign a specific employee, team, or safety committee to inspect each AED on a regular schedule. Monthly inspections work well for many workplaces because they create a dependable rhythm for checking accessories, cabinet condition, signage, and status lights.

During each inspection, verify that the AED is present, visible, accessible, and showing a ready status. Confirm that the adult pads are sealed and current, and check pediatric pads if your program includes them. Review the battery date, look for damage to the case or cabinet, and make sure the AED has not been moved behind locked doors, furniture, or stored materials.

A simple inspection record should identify the AED’s location, model, serial number, pad expiration date, battery expiration date, inspection date, and the name of the person completing the check. Document any corrective action, including the date replacement supplies were ordered and installed. These records help demonstrate a consistent readiness process and make it easier to plan purchases before accessories expire.

For larger facilities, use a centralized tracking system rather than relying on a calendar reminder attached to one person’s email. Personnel changes, remote work, vacations, and multiple building locations can all create gaps. A managed AED program gives safety leaders visibility into upcoming replacements and helps prevent preventable compliance issues.

Choose the Right Replacement Pads

Ordering by brand name alone is not enough. AED manufacturers may offer different pad configurations for different device generations, and a newer pad set may not fit an older unit. Before ordering, verify the AED model, device serial information if requested, connector style, adult or pediatric use, and whether your unit requires a cartridge-based system.

Replacement options may include adult electrode pads, pediatric pads, pads with integrated CPR feedback, or pads that support a specific rescue protocol. The least expensive option is not always the best operational choice if it does not match your equipment or the needs of your setting. FDA-approved accessories from established manufacturers help ensure the AED operates as intended.

Keep at least one current, installed pad set with the AED at all times. If your organization maintains spare pads, store them according to manufacturer temperature and environmental guidelines. Extreme heat, freezing conditions, direct sunlight, and damp storage areas can affect equipment and consumables even before their expiration dates.

What to Do With Expired or Used Pads

Expired pads should be removed from active AED service immediately and marked so they cannot be reinstalled by mistake. Used pads must also be replaced after every rescue event, even if the AED did not deliver a shock. Once pads have been applied to a patient, they are single-use accessories.

Follow the pad manufacturer’s disposal instructions and your organization’s policies. Pads used during patient care may require handling as medical waste, depending on the setting and local procedures. For unopened expired pads, disposal requirements can vary. Do not place old pads back in the AED cabinet as backups.

After a real-world AED use, inspect the device promptly. Replace pads, confirm battery readiness, download event data if required by your protocol, restock the rescue kit, and document the incident through your organization’s established reporting process. A post-event review can reveal whether access, training, signage, or maintenance procedures need improvement.

Pair Equipment Readiness With Trained Responders

Current pads are essential, but they are only one part of an effective response. Employees and designated responders should know where the AED is located, how to retrieve it, and how to follow its voice prompts. CPR/AED training builds confidence to act while emergency services are on the way.

Training should reflect your workplace realities. A single-office team may need a clear emergency action plan and several trained responders across shifts. A school, warehouse, health club, or multi-floor facility may need broader coverage, location-specific drills, and more than one AED. OSHA compliance goals, state requirements, industry standards, and internal risk assessments may shape the right program for your organization.

HealthForce Corporate helps organizations coordinate FDA-approved AED equipment, replacement accessories, certification training, and ongoing readiness support so safety teams do not have to manage each piece separately.

A dated pad package is easy to overlook because it does not create an immediate disruption. Make checking it part of the routine that protects your people. Replace supplies before they expire, keep records current, and give your team the equipment and training to respond with purpose when every second counts.
