Changing Pads and Battery: ZOLL AED 3

This is Blaire with Coro Medical, home of AED.US and today we’re going to go over how to change the pads and battery in the ZOLL AED 3.

To prepare for an emergency you want to make sure the electrodes are connected to the unit at all times. This AED uses one set of pads for both adult and pediatrics. The pads have a five year expiration. The expiration date is located on the outside of the package. You’re going to change the pads at the time of expiration or if you use the AED. To install or replace the pads, remove the current pads. Just pull up at the connector cable here, remove those. Take your new set of pads and plug the cable back into the connector. It’s as simple as that! Now the battery has a five-year expiration. The manufacture date and the use-by date are both listed on the outside of the battery. To install or replace the battery, verify the defibrillator is turned off, then you’re going to turn it around and you’re going to pull up on the clips here to remove. You take the new battery and you’re going to insert that until you hear it click. Once you’ve changed the pads or battery, verify the status indicator has a green check mark and the AED is ready for rescue.
