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.
