AED pads play a crucial role in every defibrillation attempt because they deliver the shock that can restart a normal heart rhythm during sudden cardiac arrest.
Even if the defibrillator (AED) unit is functioning perfectly, expired, dried-out, or damaged pads can make the device fail at the exact moment it is needed.
In India, where temperatures often rise above recommended storage ranges, pads can degrade even faster, making timely replacement essential.
Most AED pads come with a shelf life of two to five years depending on the model.
Once expired, the adhesive weakens, the gel dries up, and the sensors inside the pads may stop detecting heart rhythm signals properly.
If that happens, the defibrillator (AED) will not deliver a shock, and the patient’s chance of survival drops significantly.
Knowing how to replace AED pads correctly ensures the device stays ready at all times and that your staff can respond confidently during emergencies.
This guide covers simple, clear steps for replacing pads on the most used AED brands in India.
General Steps to Replace Any AED Pads
Turn off the defibrillator (AED) before removing old pads to avoid accidental alerts or errors.
Gently peel off the used or expired pads from the AED’s connector port without pulling the cable forcefully.
Take the new pads out of their sealed package only when you are ready to install them to avoid contamination.
Plug the new pad connector firmly into the AED’s designated port until it clicks or locks in place.
Place the pads back into the AED’s storage compartment or carry case in the correct orientation shown on the packaging.
Check the AED’s indicator light to ensure the unit shows a “ready” or “green” status after pad replacement.
Record the new pads’ expiry date in your defibrillator (AED) maintenance log for regular monitoring.

Philips HeartStart HS1x
- Open the pad cartridge compartment and remove the old cartridge completely.
- Insert the new Philips pad cartridge until it clicks securely into place.
- Ensure the cartridge label faces outward, and the seal remains unbroken until use.
- Confirm the AED shows a green “ready” light after installation.
Zoll AED Plus / Zoll AED 3
- Unplug the old pad cable from the top connector port.
- Remove the old CPR-D pad or universal electrode set from the case.
- Attach the new Zoll pads and plug the connector firmly until locked.
- Make sure the CPR sensor (if applicable) is centered and unused before closing the lid.
Cardiac Science Replacement Pads
- Pull out the old Intellisense pads by disconnecting the cable from the right-side port.
- Connect the new pads firmly; Powerheart AEDs will beep if the connection is incomplete.
- Place the pads flat in the pad compartment without bending the gel area.
- Verify the AED status indicator shows “rescue ready.”
Defibtech Lifeline / Lifeline View
- Detach the old pad cable from the AED’s front-facing connector.
- Insert the new adult or pediatric pad cable into the same port until it clicks.
- Store the pads correctly along the AED’s molded pad compartment to avoid creasing.
- Check that the AED performs its self-test without errors.
Mistakes to Avoid When Replacing AED Pads
Not checking pad expiry dates: Expired pads may not stick properly, making the AED unusable during a cardiac emergency.
Using pads from another brand: AED pads are not interchangeable; each model requires its own compatible electrode set.
Failing to connect the pad cable securely: A loose connector can cause the AED to show a “not ready” or error status.
Storing pads in hot or humid environments: Heat damages the gel adhesive and shortens pad life.
Opening pad packaging too early: Once opened, pads dry out and become ineffective; always keep them sealed until needed.
Ignoring AED status lights: A red or blinking error light often means pads are missing, expired, or improperly connected.
Forgetting to update the maintenance log: Recording pad replacement dates helps ensure timely future replacements.

When Should You Replace AED Pads?
AED pads should always be replaced before their expiry date, which is printed on the packaging and usually ranges from two to five years depending on the model.
Pads must be replaced immediately after any use, even if only a single shock was delivered during an emergency.
If the AED displays a “Pad Expired” or “Replace Electrode” alert, the pads should be swapped out without delay.
Pads should be replaced if the packaging is torn, unsealed, or damaged, as this can compromise both adhesive performance and sensor functionality.
Regular monthly inspections of the AED, including checking the pads, ensure that the device remains fully operational and ready for use.
