Changing Pads & Battery: Powerheart G5 AED

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 Cardiac Science Powerheart G5 AED. 

To prepare for an emergency you want to keep the electrodes and battery connected to the unit at all times. There are two types of adult pads that will go with this unit: one is the standard electrodes and the other are the ICPR pads that have CPR feedback and they will correct you, if necessary. The pads have a two-year expiration.  The expiration date is located on the outside of the package. You can also see the expiration date through the clear window on the front of the AED. You’re going to change these pads at the time of expiration or if you use the AED. To install or replace the adult electrode pads, open the lid, pull the old pads out; you’re going to take the new pads, plug them in and then you’re going to slide it through this window. Just a little tip: the Cardiac Science logo goes to the bottom right.

The battery has a 4-year guarantee the lot number and the date of manufacture are listed on the outside of the battery. The guarantee begins once you place the new battery in the AED. To install that, turn the device over, take out the old battery and you’re going to put the new battery in until you hear it click. Once you change the pads and batteries, you want to verify the rescue ready indicator is green and the AED is ready for rescue.

If you have any questions or if you want to go over purchasing options please feel free to give us a call at 800-695-1209 or go to our website Thanks for watching!
