This medical grade Powerheart AED G3 battery (part number 9146-302) is made specifically for your G3 AED device. The Cardiac Science Intellisense battery circuitry works with Rescue Ready technology to communicate battery performance, capacity, and other vital information directly to your G3 defibrillator.

This original G3 AED battery self-tests daily for presence and functionality to make sure your defibrillator is ready in a sudden cardiac arrest emergency. Each Intellisense® battery comes with a four year performance guarantee.

Renowned for its state-of-the-art STAR Biphasic and RescueCoach technologies, the Powerheart G3 automated external defibrillator is a marvel of life-saving innovation.


This original PowerHeart AED G3 battery is one of the longest-lasting batteries on the market. It has a life of four years from date of manufacture, and the expiration date is printed right on the battery.

Because the battery is made of lithium, it is important to recycle it when discarding. Be sure to recycle it at a battery-recycling drop-off location in your area.

This Intellisense lithium battery is intended for use with the following Powerheart G3 defibrillators:

  • 9300E
  • 9300A
  • 9390E
  • 9390A

The G3 AED device conducts daily self-tests to ensure that the software, hardware, pads, and battery are always in working order. If your current battery is nearing its expiration or losing sufficient power, your device should alert you of the problem. We recommend keeping a spare battery on hand to ensure that your defibrillator is always emergency-ready.
