Engineered for Critical Emergency Response. Your LifePak 12 defibrillator delivers life-saving interventions that demand consistent, reliable power delivery. This FastPak NiCd battery provides 2.4Ah capacity with 20% more runtime than standard packs - precisely when every second matters most.

As battery specialists since 2010, we've supplied over 8,500 AED batteries to emergency medical services, hospitals, and first responders where equipment reliability is non-negotiable. This USA-manufactured FastPak features proven nickel-cadmium chemistry delivering verified 12-volt output through 500+ charge cycles - designed for professionals who depend on consistent performance during critical cardiac emergencies.

Why NiCd Chemistry for Emergency Medical Equipment

From Our Field Analysis: After reviewing 1,200+ AED battery replacements across emergency services, we've identified the critical requirements for defibrillators that cannot fail during cardiac arrest interventions.

Critical Applications for FastPak NiCd Batteries:

• Emergency Medical Services: Ambulances, paramedic units, first responder vehicles requiring reliable defibrillation capability
• Hospital Emergency Departments: Crash carts, trauma centers, cardiac care units with LifePak 12 systems
• Fire and Rescue Operations: Fire departments, rescue squads, disaster response teams maintaining AED readiness
• Public Safety Installations: Police vehicles, security services, public access defibrillator programs

Direct Replacement For:

Physio-Control LifePak 12 Defibrillators - Compatible with OEM part numbers 11141-000149, 11141-000025, 11141-000044, 09-10424 - No adapters, no modifications required

We've Seen What Happens When AED Batteries Fail

• Insufficient Defibrillation Power: Degraded batteries deliver suboptimal shock energy, reducing successful resuscitation rates during cardiac arrest
• Unexpected Service Interruptions: Battery failure during emergency response creates critical delays when every second impacts patient survival
• Equipment Downtime Costs: Premature battery failure forces units offline, requiring expensive rush replacements and reducing fleet availability

We choose FDA-approved batteries accordingly. Because cardiac emergencies cannot afford equipment failure.

Q: "Does this battery include the fuel gauge like the OEM FastPak?"
A: No, this aftermarket unit does not include the fuel gauge display. However, it provides 20% increased capacity (2.4Ah vs 1.6Ah standard), delivering extended runtime. Your LifePak 12 performs regular self-diagnostics to monitor battery status, alerting you before capacity becomes insufficient.

Q: "My charger is older - how do I verify it's compatible with 1.6Ah+ batteries?"
A: Check the charger's label for amp-hour rating specifications. Older LifePak 12 chargers designed for 1.2Ah batteries cannot properly charge this 2.4Ah unit, causing undercharging and premature failure. If your charger predates 2005 or shows 1.2Ah rating, contact us for compatible charger recommendations before installation.

Q: "How often should I replace this battery in active EMS service?"
A: Based on our field data from 1,200+ EMS installations, replace every 3-4 years for high-use ambulances (10+ calls daily) or 4-5 years for moderate-use applications. Monitor self-test results - any "Service Battery" alerts warrant immediate replacement regardless of age. High-temperature vehicle storage accelerates aging by 30-40%.

Q: "Why choose High-Tech Battery Solutions over generic suppliers?"
A: After 15 years specializing in AED batteries, we understand critical equipment requirements. We stock only FDA-approved batteries, provide technical support based on real field experience with emergency services, and ship same-day for urgent replacements. Our specialists verify charger compatibility before shipping, preventing the installation errors that cause 40% of "defective" battery returns industry-wide.
