OEM Replacement Battery for G3 AEDs | 4-Year Warranty | Rescue Ready® Compatible

The Cardiac Science Powerheart G3 Intellisense Long-Life Battery (Model 9146-302) is the only manufacturer-approved battery designed for use with Powerheart G3 AEDs. Backed by a 4-year factory warranty, each unit undergoes extensive testing by Cardiac Science prior to distribution—ensuring reliability in compliance-driven and emergency-critical environments.

This non-rechargeable lithium battery features built-in Intellisense® circuitry, enabling your AED to monitor performance, track remaining capacity, and conduct daily self-tests through the patented Rescue Ready® system. Once installed, the AED continuously verifies battery health to confirm readiness for sudden cardiac arrest events.


Key Features

Intellisense Battery Technology

Built-in internal circuitry communicates battery health, capacity, and diagnostics to the AED in real-time—streamlining compliance inspections and readiness tracking.

Rescue Ready® Compatibility

Supports daily, weekly, and monthly AED self-tests by verifying charge status, connection, and remaining power. Critical for OSHA-aligned AED maintenance programs.

Long-Life Power Assurance

Delivers up to 4 years of operational life once installed, with a 5-year shelf life from the manufacture date, allowing for strategic stocking and rotation across multi-site programs.

Factory Tested & OEM Certified

Every battery is tested at Cardiac Science’s facility and meets original equipment specifications. This is not an aftermarket substitute—it’s the trusted power source used in over 500,000 deployed G3 AEDs worldwide.
