Replacing AED Plus Pads & Batteries: Step by Step

1. Order genuine parts. Use the Buy Now buttons above, or call us on 0800 55 99 55.
2. Remove the old consumables. Open the AED Plus cover, disconnect and remove the expired electrode, then remove all 10 old batteries from the rear battery compartment.
3. Install the new batteries. Insert the 10 new type 123 lithium batteries, matching the polarity markings in each battery well.
4. Press the battery reset button at the right moment. This is the step people miss: press the battery reset button only after hearing the voice prompt "IF NEW BATTERY, PRESS BUTTON". This resets the battery life counter so the device tracks the new batteries correctly.
5. Connect the new electrode and check readiness. Connect the new CPR-D-padz® electrode, close the cover, and confirm the status window shows the green rescue-ready indicator after the automatic self-test.

When should pads and batteries be replaced?

• After every clinical use, even if the pads look reusable. Electrodes are single patient use.
• At expiry: adult CPR-D-padz® and AED Plus batteries last 5 years; Pedi-padz® II last 2 years; AED 3 Uni-padz™ and battery last up to 5 years. Expiry dates are printed on the packaging.
• When the device tells you: every ZOLL AED self-tests automatically and will alert you when pads or batteries need attention. See our guide on AED maintenance best practices.
