A genuine IntelliSense non-rechargeable lithium battery built specifically for the Cardiac Science Powerheart G3 Pro AED. It comes with a fully operational replacement guarantee of 1 year from the date of installation or 12 hours of use, whichever occurs first.
The Powerheart G3 Pro AED has been discontinued by the manufacturer. This battery remains available as a genuine replacement part for AEDs already in service, but Cardiac Science is not producing new G3 Pro units.
The Cardiac Science Powerheart AED G3 Pro Non-Rechargeable Replacement Lithium Battery (SKU 9145-301) is a genuine IntelliSense lithium battery built specifically for the Powerheart G3 Pro AED. It's non-rechargeable, single-use, and backed by a manufacturer's fully operational replacement guarantee of 1 year from the date of installation or 12 hours of use, whichever occurs first.
This battery is compatible only with the Cardiac Science Powerheart G3 Pro AED. It is not interchangeable with the Powerheart G3 Plus, which uses a separate battery, part 9146-302.
Designed specifically for the Cardiac Science Powerheart G3 Pro AED (model 9300P).
The Powerheart G3 Plus uses a different battery entirely. Confirm your exact AED model before ordering.
Pair this battery with the correct Powerheart G3 electrode pads so both consumables land on the same maintenance schedule.
This listing does not include a Powerheart G3 Pro AED unit (it is a consumable replacement for existing AED owners, and the AED itself has been discontinued) or Powerheart G3 electrode pads (sold separately). Pads and batteries replace on different schedules, so check both when planning your AED's next maintenance cycle. Call Total AEDs at (855) 286-6384 to build a complete replacement bundle.
Cardiac Science's Powerheart G3 Pro and Powerheart G3 Plus are different AED models that use two different, non-interchangeable batteries. Confirm which one your device takes before ordering.
Order this 9145-301 battery when: your AED is specifically a Cardiac Science Powerheart G3 Pro.
