Why is my AED Beeping?

An AED may beep for several reasons:
  • Disconnected Electrode Pads: If your AED is beeping and requires electrode pads to be pre-connected, make sure your electrode pads are connected to the AED.
  • Low or Expired Battery: Check the charge of your battery to see if its life is depleted, and confirm the battery isn’t expired. If it’s expired, order a replacement battery.
  • Expired electrode pads: Check the expiration date of your electrode pads. Electrode pads can dry out with age or if they become unsealed, so it’s important to make sure they’re in good working order. If they’re expired or not usable, replace the electrodes.
  • Internal circuitry issue: If everything else checks out, the beeping may be caused by an internal circuitry issue. AED Superstore recommends you contact the AED manufacturer for warranty service.
If you other questions or need replacement electrode pads or batteries, call AED Superstore at 800-544-0048 for further assistance and our trained Customer Care Agents will be happy to assist you.

Hi how do you disconnect the electrode pads ?

Hello Patricia,

This depends on the AED you have, but most are connected with a cable. New pads will come with a new cable. The exception are AEDs which use a cartridge system such as the Philips OnSite or the HeartSine PAD AEDs. In that case, the entire cartridge will need to be removed in order to disconnect them from the unit.

If you replaced the battery you must open the door to the AED and let it reset.
