How to Change the Cardiac Science G3 Battery

Changing out the Cardiac Science G3 Battery

Locate the Cardiac Science G3 AED battery at the bottom of the device.. Press the clip at the side of the battery and remove it. Do not be alarmed if the device beeps, this is normal.

Take the new battery and slide it into the bottom of the AED. Press down until you hear a click and the device beeps.

From there, open the front of the AED and let the unit talk. The unit will say “stay calm and follow these instructions”.

You can then close the front cover and check the rescue-ready light located at the top right.

Why is my Cardiac Science Powerheart G3 Beeping?

Oftentimes, the device is beeping due to the pads or batteries expiring. If the device’s pads and batteries are within their expiration dates but the rescue-ready indicator is still red, we recommend calling ZOLL’s (the company that bought out Cardiac Science) technical support team.

Cardiac Science Powerheart G3 Shelf Life?

The battery has a 5-year shelf life calculated from the ‘Manufactured on Date’. For example, if the battery’s MoD is January 1, 2020, the battery will be operable until January 1, 2025.

Are After-Market Batteries Available?

After-market and ‘re-celled’ batteries do exist, but AED Brands does not sell them nor recommend them.

For a myriad of reasons, after-market batteries are a potentially dangerous option. Yes, they often cost less but do not have FDA approval or a manufacturer guarantee.

Using non-approved batteries voids the device’s warranty and removes the manufacturer’s indemnification, potentially putting the owner at risk of a lawsuit in the event the machine is deployed. There is never a time we would recommend using after-market supplies for a medical device.
