Is your defibrillator rescue ready? Maintaining a defibrillator ensures it will function in an emergency. This is crucial because for every minute without CPR and defibrillation, the chances of survival drop by 10%. Despite this, regular upkeep is frequently overlooked.
In this guide, our experts will walk you through why regular maintenance of your defibrillator is essential and everything you need to know to keep your defibrillator rescue-ready, from routine checks to essential maintenance tasks.

Why Should I Check My Defibrillator?
Ignoring maintenance can put lives at risk. This is because early defibrillation, within 3–5 minutes of collapse, can increase survival rates by 50-70%. In contrast, the survival rate drops by about 10% each minute longer, so a working defibrillator is essential.
Regularly check your defibrillator to make sure that its batteries, pads, and other internal mechanisms are working.
How Often Should My Defibrillator Be Checked?
Most AEDs perform automatic self-tests depending on the model. If a device fails a self-test, then it might make a noise, flash and/or display an error. It is a good idea to familiarise yourself with the user manual to understand a) if your device self-tests and b) what your specific device will do if it fails the self-test. Keep in mind that not all devices conduct the same daily self-tests, so you should refer to the user manual to be sure.
In addition to the self-tests, you will also need to conduct visual inspections weekly. We’ll share more on what you need to check in the next section.
A defibrillator engineer or technician can also conduct deeper checks, including live circuit testing and firmware updates, in instances where there is no designated “Responsible Person” or for peace of mind if the defibrillator hasn’t been maintained in a while.
Did you know? If you register your defibrillator on The Circuit, the national defibrillator network, you will receive regular reminders to record your checks and replace your electrode pads. Find out more about registering your defibrillator here.
How Do I Check That My Defibrillator Is Working?
Here are the basic steps you need to follow to check your defibrillator.
- Defibrillators have a status on the front of the device. Check the status indicator for green, which tends to indicate that the defibrillator is ok. If there is beeping, flashing or an X on the front, these are usually signs that a device has failed its self-test. Check your user manual if you are not sure what the status means, or consult our Troubleshooting articles for further guidance.
- Check the rest of your defibrillator for obvious signs of damage or use.
- Check to see if the items that are usually stored with it are still there, such as a first response kit, face shields, scissors, razor, cleansing wipes and required paperwork.
- Check the expiry date on the sticky pads and batteries. If they are out of date or low charge, replace them.
- Though not essential, you can also give the defibrillator or its storage container a wipe with a damp cloth to prevent the build-up of dirt and grime.
Once the check is complete, make sure the defibrillator is properly stored and that all signage is clear. And don’t forget to update your documents. You should maintain logs of all checks, replacements, services, and incidents.

How to Maintain a Defibrillator
Most defibrillators self-test on a daily, weekly or monthly basis, which means that the device would signal with a flashing light or audible alert if there were a problem. However, you still need to conduct regular checks. On a weekly basis, you should:
- Check the standby light and visual status.
- Ensure the unit is clean and accessible.
- Replace expired pads or batteries.
- Confirm the presence and condition of accessories and required documents.
After each use, you should:
- Replace pads as they are mandatory single-use items, and possibly the battery, depending on the model.
- Clean down the defibrillator, download event data if required, reset, and perform a self-test.
FAQs
Do Defibrillator Pads & Batteries Expire?
Pads typically expire between 1.5–5 years, and batteries between 2–7 years, depending on the model. Please check your user manual and the expiration date on your battery or pad. Pad and battery expiry dates are typically displayed next to an hourglass or egg timer symbol.
Can Defibrillator Pads be Reused?
No. Defibrillator pads must be replaced after each use.
How Do I Dispose of Expired or Used Pads and Batteries?
Expired pads, which are unused, can go into general waste. However, used pads might be contaminated and, therefore, need to go through infectious waste disposal. Electrodes should have wires cut before disposal. Batteries must be recycled, and not thrown in regular bins.
Do I Need Professional Servicing?
Yes, professional servicing is typically recommended annually, but consult your defibrillator’s user manual for specific guidance. Professional maintenance enables complete functional inspections, software upgrades, and checks adherence to safety standards.
