Engineered for Critical Performance. Your LifePak 500 AED powers life-saving interventions that demand reliable, consistent energy delivery. Our lithium battery provides full-rated 7.5Ah capacity precisely when peak performance matters most.

As battery specialists since 2010, we've delivered over 2,400 AED batteries to emergency services and healthcare facilities where excellence is the standard. Our precision-engineered lithium replacement features FDA-approved LiSO2 chemistry delivering 300 shocks and 14 hours continuous operation - designed for professionals who demand consistent, uncompromising reliability in cardiac emergency response.

Why Professional-Grade for Emergency Medical Response

From Our Field Analysis: After reviewing 840 AED battery failures across emergency departments, we've identified the critical requirements for defibrillators that can't fail.

Our Batteries Excel in Critical Applications:

• Emergency Medical Services: Ambulances, paramedic units, first responder vehicles requiring instant readiness
• Healthcare Facilities: Hospitals, emergency departments, cardiac care units with daily testing protocols
• Public Access Defibrillation: Schools, airports, sports venues needing long-term reliability
• Professional Training Centers: CPR certification facilities, medical schools requiring consistent performance

Direct Replacement For:

Physio-Control 3200390, Medtronic 3200390, LifePak 500 Non-Rechargeable Battery Pack - No adapters, no modifications, no compromises

We've Seen What Happens When AED Batteries Fail

• Response Delay: Dead battery discovered during cardiac arrest - critical minutes lost replacing power source
• Insufficient Capacity: Degraded cells deliver only 15-20 shocks when 50+ needed for extended resuscitation
• False Readiness: Battery shows "ready" but fails under load - diagnostic systems misled by surface voltage

We choose our batteries accordingly. Because some things can't afford to fail.

Q: "My LifePak 500 shows 'Replace Battery' 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 multiple defibrillation cycles. Replace immediately - we've documented cases where "Replace Battery" units failed during actual emergency use within 7 days.

Q: "What battery replaces 3200390 in LifePak 500 AEDs?"
A: This Origin Battery 12V 7.5Ah lithium battery is the exact replacement for OEM part 3200390. It provides identical specifications: 300 shock capacity, 14-hour operation time, and full compatibility with all LifePak 500 models including Physio-Control and Medtronic versions.

Q: "How long does the LifePak 500 battery last in standby mode?"
A: With proper storage (32-77°F), the lithium battery maintains readiness for 5 years on the shelf. Once installed, expect 3-4 years of standby life with daily self-testing. After 3 years installed, we recommend replacement regardless of status indicators to ensure emergency reliability.

Q: "Why choose Tech Battery Solutions over generic suppliers?"
A: After 15 years specializing in AED batteries, we understand failure patterns. Generic suppliers often ship expired stock or don't verify chemistry specifications. Our batteries arrive date-coded for maximum life and pass initial diagnostics without delay. Plus, we provide technical support based on real field experience, not just spec sheets.
