ZOLL Medical 9146-302 Cardiac Science Intellisense Powerheart G3 Battery

An AED only counts as equipment if it will fire on the day someone collapses.

Defibrillators spend almost all of their service life doing nothing. That is the point — and it is also the risk. The unit sits on a wall through years of quiet, and the only thing standing between a dead battery and a failed rescue is a replacement schedule somebody actually keeps. When an AED does get pulled off the bracket, there is no time to troubleshoot power.

The ZOLL Medical 9146-302 Cardiac Science Intellisense Powerheart G3 Battery is the non-rechargeable lithium battery pack for compatible Powerheart G3 AEDs. It is the part that keeps the unit running its self-tests, holding its charge through the standby years, and delivering therapy when the pads go on a patient.

Dependable Power for Compatible Powerheart G3 AEDs

Intellisense lithium chemistry is built for the long standby duty an AED demands: minimal self-discharge across years on the wall, then full output on demand. According to ZOLL's product documentation, the 9146 lithium battery carries an estimated five-year shelf life from the date of manufacture and a four-year full operational replacement guarantee from installation, and can support up to 290 shocks under specified conditions.

Key features include:

• Non-rechargeable Intellisense lithium pack — designed for long-term standby readiness
• Estimated 5-year shelf life — measured from the date of manufacture
• 4-year full operational replacement guarantee — from the date of installation
• Up to 290 shocks — under the conditions specified by ZOLL
• Built for compatible Powerheart G3 models — including the AED G3 9300A and 9300E
• Straightforward installation — a routine swap during scheduled AED maintenance

Why Battery Replacement Belongs on a Schedule

AED failures at the moment of use are rarely dramatic; they are almost always a maintenance gap. Batteries age whether or not the unit is ever deployed, and a pack that is past its guarantee window is a pack you are trusting on hope rather than on documentation. Tracking manufacture dates and installation dates — and replacing on the earlier of the two limits — turns readiness from an assumption into a record.

Practical reasons to keep a spare in the program:

• Keeps units in service instead of out of rotation waiting on parts
• Removes guesswork during inspections and compliance checks
• Supports multi-site programs where several AEDs come due at once
• Avoids emergency ordering when a self-test flags low power
• Makes documented readiness easy to demonstrate to auditors and safety officers

Built for Environments Where Response Time Decides Outcomes

The 9146-302 supports compatible Powerheart G3 AEDs in the places where a defibrillator has to work on the first attempt: hospital corridors, ambulances, plant floors, school gyms, and public-access cabinets. For organizations running an AED program across multiple buildings, standardizing on the correct replacement battery keeps every unit on the same maintenance cycle and the same paperwork.
