Cardiac Science Powerheart G3 Pads & Battery: Part Numbers (and What Comes Next)

The Cardiac Science Powerheart G3 has a large installed base and is still going strong on a lot of walls — but it has reached end of life. That changes the maintenance calculation, so this guide covers both what it takes today and when to stop investing in it.

The battery decision on an end-of-life device

The G3 battery is one of the more expensive AED consumables, which makes the re-celled option 9146-ABE genuinely worth considering. It is an aftermarket cell replacement rather than a Cardiac Science OEM pack, at a meaningfully lower price.

Here is the honest framing. On a current-generation AED with years of service ahead, we would usually steer you to the OEM part — particularly if a medical director or insurer specifies OEM consumables. On a G3 that is already past end of life, spending premium money on a battery for a device you will replace within a few years is harder to justify. If your programme permits aftermarket parts, the re-celled pack is a reasonable way to bridge the gap.

What end of life actually means for you

End of life does not mean your G3 stops working tomorrow. It means the manufacturer has ceased production and support will wind down — so over time, parts availability tightens and there is no repair path if the unit itself fails a self-test.

Practical guidance:

• Keep it maintained and on the wall. A working G3 with in-date consumables is far better than an empty bracket.
• Stop troubleshooting a failing unit. If pads and battery are in date and correctly seated and it still chirps, that is the device telling you it is done. See why is my AED beeping.
• Budget for replacement rather than being forced into an emergency purchase. AEDs run roughly 8 to 10 years from manufacture, so check the date on yours.

Pediatric coverage

The G3 uses separate paediatric electrodes 9730-002 with their own expiration date. This is the item most often found expired at inspection.

Frequently asked questions

What pads does the Powerheart G3 use?

Adult electrodes are part 9131-001 and paediatric electrodes are part 9730-002. Both fit the Powerheart G3 and G3 Pro.

Is the Powerheart G3 discontinued?

Yes, the G3 has reached end of life. Existing units continue to work and consumables remain available, but the manufacturer has ceased production and support will reduce over time.

Can I use a re-celled battery in my Powerheart G3?

Yes. The re-celled pack, part 9146-ABE, is an aftermarket alternative to the OEM 9146-302 at lower cost. Confirm that your AED programme or medical direction permits non-OEM consumables before ordering.
