Installing an AED is a great first step. But an AED only saves a life if it works the moment someone needs it. Pads can expire, batteries run down, indicator lights fail, and cabinets can get damaged over time. That is why regular checks and simple maintenance routines are so important.
This guide walks you through the practical side of keeping your AED ready, based on manufacturer instructions, industry norms, and publicly available guidance. Nothing complicated. Just the essentials every business should know.
Why AED upkeep matters
AEDs are designed to be simple to use, but they still rely on parts that age. Pads dry out. Batteries lose charge. Dust builds up. A small issue can make the unit unreliable in an emergency.
Routine checks help make sure your AED stays:
- Visible and easy to reach
- Powered and ready for use
- Up to date with pads and batteries
- Free from cabinet or signage damage
- Clear of obstructions or hazards
Most manufacturers recommend quick visual checks each month, supported by more detailed servicing every six months.
What to check regularly
You do not need to be a technician to keep an eye on your AED. A simple visual check takes less than a minute.
Here is what to look for:
1. The indicator light
Most AEDs have a small window that shows a green or flashing light when the device is ready.
If the light is red, off, or showing a warning symbol, contact a service provider.
2. Battery status
Batteries last several years, but they still expire. Check the expiry date printed on the battery or the unit.
3. Pad expiry dates
Pads have a shelf life and must be replaced once expired.
Expired pads can fail to stick, which affects the shock delivery.
4. Cabinet and signage
Make sure the cabinet is clean and undamaged.
Check that signage is still visible and easy to understand.
5. Obstructions
The AED should always be easy to get to.
No boxes, furniture, or clutter should block access.
When a full service is needed
A full service should include:
- Opening the unit and checking connections
- Replacing pads and batteries before expiry
- Confirming the unit is functioning correctly
- Ensuring placement and visibility still meet best practice
- Updating digital records for audits or safety reviews
Most organisations find it easier to outsource this to a provider so nothing gets missed.
What to do if the AED is used
After an incident:
- Notify your AED provider as soon as possible
- The unit will need new pads
- The battery may need replacing
- A technician will check functionality before the AED goes back on the wall
There may be a small call-out fee, depending on your maintenance arrangement.
