Cardiac Defibrillators Frequently Asked Questions

My defibrillator keeps beeping. How can I fix this?

There are two reasons that your defibrillator is beeping.

1. The electrodes have expired.

2. The battery has expired and/or is running low.

It is likely that you will need to either order a new pair of electrode pads, and/or a new AED battery. Ordering these items is easy and can be done through our online order form. In the meantime, you can stop the beeping by simply removing the battery from the AED. For more information on how to check and maintain your AED, click here.

How do I order a new AED battery or electrode pads?

This can easily be done by completing our online order form which can be accessed here. If you are unsure about exactly which accessories you need, please give us a call on (03) 9429 2666 or email admin@cardiacdefibrillators.com.au.

I would like to be sent reminders when my electrode pads or battery are due to expire – how can I arrange this?

This can be arranged within a few minutes by registering your AED(s) on our website. Registering your AED ensures you will receive email reminders prior to the expiry of your electrodes and/ or battery. It also guarantees that Cardiac Defibrillators has your most current and up-to-date contact details. To register your AED, click here.

How do I dispose of expired electrode pads and/or AED battery?

All electrode pads can be disposed of through your general rubbish. As your AED battery is a lithium battery, you will need to contact your local council to either arrange collection or a trip to your nearby recycling and waste centre (otherwise known as a ‘tip’).

Do your defibrillators run self-tests?

Cardiac Defibrillators’ Powerheart AEDs are the only units on the market to comprehensively self-test the battery, electrodes and circuitry every single day. When looking for the most reliable and easy to use AED on the market, both the Powerheart G3 Elite and the new Powerheart G5 AED are the most popular choice. Both AED models conduct daily self-tests of all critical components – the battery, internal circuitry, pads and software.

I have a Powerheart AED (G3 or G5) from Cardiac Science Australia. Can you still help me with my AED needs?

Cardiac Science is the former trading name of Cardiac Defibrillators. While our business name and logo have changed, please be assured that we are the same team of people who continue to supply the same Powerheart AEDs and accessories. Should you have any issues with an AED previously purchased from Cardiac Science Australia, please contact us at admin@cardiacdefibrillators.com.au or call (03) 9429 2666.
