AED Maintenance Checklist: Monthly, Annual, Pads, Batteries, and Inspection Logs

An AED maintenance checklist helps keep an automated external defibrillator ready before an emergency happens. AEDs are sophisticated medical devices designed to guide rescuers through sudden cardiac arrest response, but the device is only useful if it can be found, powered, opened, and used with pads that are present and in date.

For most workplaces, schools, churches, gyms, offices, and public facilities, AED maintenance is not one single task. It includes monthly visual inspections, pad and battery tracking, cabinet and signage checks, documentation, responder awareness, and replacement planning. The goal is simple: if someone collapses today, the AED program should not fail because of an expired pad set, a dead battery, a missing response kit, or an inspection log that no one owns.

Monthly AED maintenance checklist

Use a monthly AED maintenance checklist to confirm basic device readiness. Always follow the AED manufacturer’s instructions and your organization’s written response plan.

• Confirm the AED is in its assigned location and visible.
• Check that the status indicator shows ready.
• Confirm adult pads are sealed, connected if required, and not expired.
• Confirm pediatric pads or pediatric mode accessories are present where children may be served.
• Check the battery install date, expiration date, and device alerts.
• Make sure the cabinet, wall sign, and directional signage are visible and accessible.
• Confirm the response kit is present, including scissors, razor, gloves, towel, and barrier device if included.
• Document the inspection date, initials, device condition, and any corrective action.

Annual AED maintenance checklist

An annual review should go deeper than the monthly visual check. It is a good time to review manufacturer guidelines, update the AED inventory, confirm responder awareness, and compare the current program against facility risk and applicable AED laws or internal policy requirements.

• Review every AED location and confirm the placement still makes sense.
• Check all pad and battery expiration dates for the next 12 to 24 months.
• Confirm replacement supplies are compatible with the exact AED model.
• Review AED inspection logs for missed months or recurring device alerts.
• Confirm staff know where the AED is located and who calls 911.
• Review CPR/AED training expectations for the organization.
• Update emergency response contacts, site maps, and internal procedures.
• Confirm the AED program owner and backup owner are still assigned.

Pad and battery replacement planning

Expired pads are one of the most common AED readiness gaps. Pads dry out over time, and the adhesive gel must work properly so the AED can analyze rhythm and deliver therapy when appropriate. Batteries also age and may fail readiness checks before or near the printed replacement date.

Do not wait until the expiration month to start replacement planning. Facilities with multiple AEDs should keep a simple pad and battery inventory showing model, serial number, pad type, expiration date, battery date, location, and replacement status. If your organization manages many devices, AED management can help reduce manual tracking and missed replacements.

Documentation and inspection logs

AED inspection logs create accountability. They show that someone checked device readiness, identified issues, and took action when pads, batteries, cabinets, or signs needed attention. Documentation may also matter for internal safety programs, insurance reviews, school or facility policies, and state-specific AED program expectations.

At minimum, record the AED location, inspection date, status indicator, pad expiration, battery status, inspector initials, and corrective action. If a device is moved, used, serviced, or replaced, document that event separately so the program history stays clear.

When to replace supplies immediately

Replace supplies immediately when pads are expired, packaging is open or damaged, the AED shows a warning, the battery is depleted, the device has been used in an emergency, or manufacturer guidance calls for replacement. After any rescue event, the AED should be reset, event data should be handled according to the organization’s procedure, and used pads or accessories should be replaced before the AED is returned to service.

Why AED maintenance matters

AED maintenance protects the investment your organization already made. Buying the AED is only the first step. Ongoing device readiness, compatible replacement supplies, responder awareness, and clear ownership are what make the AED program dependable during a real cardiac emergency.

Organizations should also remember that AED laws and requirements vary by state and setting. A workplace, school, gym, church, or public facility may have different expectations for registration, inspections, training, signage, EMS notification, or documentation. Review applicable requirements and keep program records aligned with your location and organization type.

Common AED maintenance mistakes to avoid

Many AED programs fail in small, preventable ways. The AED may be present, but the cabinet is blocked, the location is not known by newer employees, the adult pads expired months ago, or the battery alert was ignored because no one understood who owned the corrective action. A checklist should make these gaps visible before an emergency.

Do not assume that a green status light is the entire inspection. The visual indicator is important, but a complete AED maintenance review also checks accessories, expiration dates, cabinet access, signage, location records, and documentation. If your organization has more than one AED, the checklist should identify each device separately so supplies are not mixed between models.

Who should own AED maintenance?

Every AED program needs a named owner. In a small office, that may be the office manager, safety coordinator, practice administrator, school nurse, facility director, or HR manager. In a larger organization, responsibility may be shared between safety, facilities, risk management, security, or operations. The important point is that one person and one backup person should be responsible for confirming inspections are completed and replacement supplies are ordered on time.

The owner does not need to be a medical expert, but they do need a reliable process. A good process includes calendar reminders, an inspection log, a list of AED locations, pad and battery expiration tracking, and a way to escalate problems when a device is not rescue-ready.

Multi-site AED maintenance

Multi-site AED programs are more difficult because each location may have different staff, different state AED requirements, different device models, and different replacement dates. A spreadsheet can work for a small program, but it becomes risky when dozens of devices, pads, batteries, cabinets, and inspection logs are involved.

For multi-site organizations, AED management should create one central view of device readiness. The team should know which AEDs are ready, which supplies expire soon, which inspections are overdue, and which sites need follow-up. This is especially important for franchises, corporate offices, school districts, healthcare groups, gyms, manufacturing companies, churches with multiple campuses, and public facilities.

After an AED is used

An AED that has been used in a rescue should not simply be placed back in the cabinet. Follow the manufacturer’s instructions and your internal emergency response procedure. Used pads typically need replacement, the device may need to be checked or reset, event information may need to be handled, and the response kit may need to be restocked.

Document the use, the date, the device involved, the supplies replaced, and who returned the AED to service. This post-use process helps ensure the AED is ready for the next emergency and that the organization has a clear record of corrective action.

How AED management reduces missed maintenance

Manual AED maintenance can work when the program is small and one person is consistently responsible. It becomes less reliable when employees change roles, sites are added, devices are replaced, or pads and batteries expire on different dates. AED management gives the organization a repeatable system instead of relying on memory.

AEDUSA’s AED management support can help track device locations, expiration dates, inspection activity, and readiness issues. For organizations that want stronger oversight, AEDMD Plus can support state-specific AED program documentation, readiness checks, and follow-up when an AED needs attention. That type of process is especially valuable when an organization wants proof that the program is being monitored rather than hoping every site remembers its monthly checks.

What to include in a simple AED maintenance log

A good AED maintenance log does not need to be complicated. It should include the AED location, model, serial number, inspection date, status indicator, adult pad expiration date, pediatric pad expiration date if applicable, battery date, cabinet condition, signage condition, inspector name or initials, and any corrective action. If the AED fails a check, document when the issue was corrected and who returned the device to service.
