Why Professional-Grade for Life-Saving Equipment

From Our Field Analysis: After reviewing 847+ defibrillator battery failures across emergency services, we've identified the critical requirements for medical equipment that can't fail.

Our Batteries Excel in Critical Applications:

• Emergency Medical Services: Ambulances, rescue units, hospital emergency departments
• Fire Department Response: First responder vehicles, rescue operations, cardiac emergency calls
• Hospital Critical Care: Emergency rooms, cardiac care units, surgical suites
• Medical Training Facilities: EMS training centers, nursing schools, medical education programs

Direct Replacement For:

OEM Part Number 11141-000112 for Physio-Control Lifepak 20e Defibrillator/Monitor systems - No adapters, no modifications, no compromises

We've Seen What Happens When Batteries Fail

• Emergency Response Delays: Dead batteries during cardiac arrest calls cost precious minutes when seconds matter
• Equipment Downtime: Failed batteries take critical defibrillators out of service during peak emergency periods
• Diagnostic Failures: Weak batteries cause false error readings, delaying treatment and undermining confidence

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

Q: "My Lifepak 20e shows 'Service 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 extended monitoring or multiple defibrillation attempts. Replace immediately - we've documented cases where "Service Battery" 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 18 months with proper storage (under 85°F), likely environmental. Over 30 months is normal end-of-life. Between 18-30 months, high-heat exposure typically accelerates aging. We provide capacity testing guidance for borderline cases.

Q: "Can I use this battery in other 11.1V medical systems?"
A: No. While voltage matches, the Lifepak 20e has specific charge characteristics and connector requirements. Other 11.1V systems may 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 suppliers?"
A: After 15 years specializing in medical device batteries, we understand the failure patterns. Generic suppliers often don't pre-charge batteries or understand Physio-Control's diagnostic requirements. Our 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.
