How to Change Pads and Batteries on the Cardiac Science Powerheart G3 Plus and G3 Pro with Blaire

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 G3 Plus and G3 Pro AED. Now the pads and batteries, how you change those, are the exact same for both of these units, so I’m just gonna show you on the G3 Plus, but just keep in mind that it’s the same for the G3 Pro as well. To change the battery, which is located in the bottom of the AED, pop it out…now there is a reference number and a lot number listed on the battery, there is also a date. That is the date of manufacture. This battery has a 4 year full operational guarantee. That date starts as soon as you put the new battery in your AED. To do so, pop it right in the bottom of the AED.

Now we are going to go over how to change the pads. For this I am going to take the battery out so that you guys can hear me in this video while I am changing out the pads. Normally, you will want to leave that battery in at all times. To change the pads, just press the button and open the lid, you unplug those, and you’ll get a new set of pads. The expiration date for these are listed in two different places: one on the front, and one on the back. These have a two-year expiration so you’re going to want to change those before that expiration date OR if you use you AED for any reason, you’re gonna need to change those pads as well. To insert the new ones you’re going to line up the red and white to the red and white here, plug it in, put that back in the little pocket here, and close the lid. Now with these devices, once you change the pads or battery, the ready indicator will stay red until it does its nightly self-test. To go ahead and change that to green you are going to open the lid, close it right back, and the indicator will switch to green. Once you see the green indicator you know everything is good to go and that you are Rescue Ready.
