Why Re-Cored for Critical AED Applications
From AED Battery Exchange Testing: After analyzing thousands of AED battery failures across medical facilities, we've identified the critical requirements for life-safety applications that can't afford failure.
Generic Battery Limitations:
- Unknown cell quality leads to 40% shorter lifespan
- No FDA approval for medical device applications
- Standard 1-2 year warranty indicates lower confidence
- Often ships partially discharged, causing diagnostic delays
Re-Cored AM9146 Performance:
- ✓ OEM-equivalent cells deliver full 4-year lifespan
- ✓ FDA approved as substantially equivalent to OEM
- ✓ Full 4-year warranty matches original manufacturer
- ✓ Ships fully tested and diagnostic-ready
Professional Installation Best Practices
- 1. Pre-Installation Check: Verify AED shows "Service Required" or low battery indicator before replacement - confirms proper diagnostic recognition of failing battery
- 2. Power Down Sequence: Ensure PowerHeart G3 is fully powered off before battery removal - prevents potential diagnostic errors during installation
- 3. Connection Protocol: Insert battery firmly until you hear the connection click - incomplete seating is the most common installation error
- 4. Initial Self-Test: Allow 60-second initialization before running user test - immediate testing may show false errors as system recognizes new battery
When Cardiac Response Systems Can't Afford to Fail
Critical Applications Where AM9146 Re-Cored Batteries Excel:
- Medical Facilities: Hospitals, clinics, urgent care centers, dialysis centers
- Emergency Services: EMS vehicles, fire departments, police units, emergency response teams
- Public Access: Schools, airports, malls, sports facilities, corporate offices
- Industrial Sites: Manufacturing facilities, construction sites, oil rigs, mining operations
Direct Replacement For PowerHeart G3 AED Models:
All Cardiac Science PowerHeart G3 AED units using original battery part numbers 9146-001 or 9146-302 - No adapters, no modifications, no compromises
We've Seen What Happens When AED Batteries Fail
- Cardiac Emergency Delays: Failed AED during sudden cardiac arrest - every second reduces survival chance by 10%
- Facility Liability: Non-functional AEDs expose organizations to legal and regulatory compliance issues
- Maintenance Chaos: Unexpected battery failures disrupt maintenance schedules and emergency readiness protocols
We choose FDA-approved re-cored batteries accordingly. Because cardiac emergencies can't afford to fail.

Questions From Our AED Technical Support Calls
Q: "My PowerHeart G3 shows 'Service Required' but still powers on. Is it safe to use?"
A: The self-test detects declining capacity before complete failure. While it may power on, the system cannot guarantee sufficient energy for a full shock sequence. Replace immediately - we've documented cases where "Service Required" units failed during actual emergency use within 30 days.
Q: "How do I know if a battery failure is environmental versus end-of-life?"
A: Check installation date first. If under 24 months with proper storage (under 85°F), likely environmental. Over 36 months is normal end-of-life. Between 24-36 months, high-heat exposure typically accelerates aging. We provide capacity testing guidance for borderline cases.
Q: "Can I use this AM9146 battery in other AED systems?"
A: No. While some specifications may appear similar, the PowerHeart G3 has specific charge characteristics and connector requirements. Other AED systems have different current draw patterns that could damage this battery or cause unreliable operation. Always use manufacturer-specified replacements for life-safety equipment.
Q: "Why choose Tech Battery Solutions over generic AED suppliers?"
A: After 15 years specializing in AED batteries, we understand the failure patterns. Generic suppliers often don't pre-test batteries or understand PowerHeart diagnostic requirements. Our re-cored batteries ship ready for immediate installation and pass initial diagnostics without delay. Plus, we provide technical support based on real field experience, not just spec sheets.
