An AED or defibrillator is only ready to save a life if its battery and electrode pads are in date and working. This guide explains how to check, choose and replace defibrillator batteries and pads in Australia, for popular models from Philips, ZOLL, Physio-Control (LIFEPAK), Defibtech and Mindray.

How to Check Your AED Is Ready
- Status indicator: most AEDs have a ready light or display. Check it regularly (weekly is a common routine) and act on any warning.
- Battery date: AED batteries have an install-by or expiry date printed on the label. Replace the battery before that date or when the AED reports a low battery.
- Pad expiry: electrode pads have a printed expiry date because the gel dries out over time. Replace pads before they expire and always after use.
- After every use: replace the pads, and check the battery status before returning the AED to service.
Choosing the Right AED Battery
AED batteries are model-specific. Always match the battery to the exact model of your defibrillator and check the part number on your old battery. Examples we stock include:
- Philips HeartStart HS1 / FRx: M5070A battery
- Philips HeartStart FR2 / FR2+: M3863A battery
- Philips HeartStart FR3: 989803150161 battery
- Philips HeartStart MRx: MRx battery
- ZOLL R Series: ZOLL SurePower II battery and R/E Series battery
- LIFEPAK 1000: LIFEPAK 1000 battery
- Defibtech DDU-2000 series: DCF-2003 battery pack
- Mindray BeneHeart D5 / D6: LI34I001A battery
Rechargeable or Non-Rechargeable?
Public-access AEDs such as the HeartStart HS1, FRx and FR3 use non-rechargeable lithium batteries designed to sit in standby for years. Hospital defibrillators and monitor/defibrillators, such as the HeartStart MRx and ZOLL R Series, usually use rechargeable batteries that are charged in the device or a charger.
Choosing the Right Defibrillator Pads
Pads must suit both your defibrillator and the patient.
- Connector: pads use different connectors for different models. Check the part number on your current pads.
- Adult or child: many AEDs use separate infant/child pads or a key that reduces the energy. See our Philips M3504A infant pads and M3717A paediatric pads.
- Radiotransparent pads: these let X-rays pass through and are useful in hospital settings. See the Philips M3718A radiotransparent pads.
- Preconnected pads: pads that stay plugged in, such as the Philips 989803166021 preconnect pads, save time in an emergency.
AED Storage and Training
Store AEDs where they are easy to find and protected from damage. An AED cabinet with alarm and strobe or a carry case such as the Philips HS1 carry case keeps the unit ready to grab. For staff training, an AED trainer lets people practise without using a live defibrillator.
Frequently Asked Questions
How do I know which battery my AED needs?
Check the model name on the AED and the part number on the existing battery. Each product page lists the models the battery is made for.
Can I use expired pads?
No. Expired pads may not stick properly or deliver therapy correctly. Replace them before the expiry date.
