Basic AED Defibrillator Maintenance

Why AED Maintenance Matters

An Automated External Defibrillator (AED) is one of the most important pieces of lifesaving equipment you can have, whether at work, in the community, or at home. But owning an AED isn’t enough. Regular AED maintenance ensures your device will work instantly and effectively during a cardiac emergency.

Don’t AEDs Do Their Own Self-Checks?

Yes! Most AEDs perform automatic self-tests daily, weekly, or monthly. These checks look at battery status, internal circuitry, software, and pad connection.

However, automatic tests can’t check everything. They won’t detect damage on the outside of the unit, expired pads, missing accessories, or signs of misuse. That’s why a simple manual inspection is still essential.

How Often Should You Check Your AED?

A quick visual inspection once a month is recommended for most workplaces and facilities.
If your AED is in a high-use or outdoor/public area, consider inspecting it weekly.

Do You Need to Be an Expert?

No! AED maintenance is simple and can be done by anyone following the manufacturer’s manual and a basic checklist. No technical background required.

Let's Begin!

Physical Inspection

Check the readiness indicator
- Ensure the AED shows a “ready,” green light, or OK symbol. If it shows red or a warning icon, schedule servicing immediately.
Inspect the AED case
- - Look for cracks, moisture, excessive dust, or signs of damage.

Confirm pads/electrodes
- Are pads sealed and in date?
- Are cables connected properly?
- Are spares included (if your model requires)?

Check the battery status
- Make sure it’s within its expiry date and the device indicates sufficient charge.
Verify accessories
- Ensure you have:
  - CPR face shield/mask
  - Scissors
  - Razor
  - Gloves
  - Wipes or towel

Manual / Forced Self-Test

Most AEDs allow you to run a manual self-test by pressing a dedicated button. This can:

Re-check battery levels
Test internal circuits
Confirm software function

Always follow the instructions in your AED’s user manual when performing a forced test.

Cleaning the AED

Wipe the unit with a soft cloth dampened with mild soap and water.
Do not use strong chemicals, alcohol, or spray cleaners directly on the device.
Do not immerse any part of the unit in water.
Keep the case dry and free from dust.

Battery Care

Keep track of battery expiry dates.
Replace immediately if the AED shows a battery warning.
After each use, replace both the battery and pads unless stated otherwise by the manufacturer.

AED Inspection Tag

An inspection tag is a simple but important part of AED maintenance.
It helps track when checks were completed and ensures accountability.

Your inspection tag should include:

Date of inspection
Initials or name of the person who checked the unit
Pads expiry date
Battery expiry date
Any notes (e.g., “ordered new pads”)

Using an inspection tag makes it easy for multiple staff members or teams to stay on top of AED readiness and avoids missed or overdue checks.
