When Cardiac Emergency Response Can't Fail. Your Cardiac Science AED protects life-critical systems - medical equipment that must deliver reliable defibrillation when every heartbeat counts. Based on our analysis of 1,200+ AED battery installations across medical facilities, we've identified the performance standards essential for emergency cardiac response. Our FDA-approved 9141 replacement delivers full-rated 7.5Ah capacity exactly when failure isn't an option.

As battery specialists since 2010, we've supplied over 4,100+ professional AED batteries to hospitals, emergency services, and healthcare facilities where device failure means the difference between life and death. Our professional-grade 9141 features sealed lithium-sulfur dioxide technology delivering 300+ discharge cycles - exactly when you demand uncompromising reliability in critical cardiac emergency situations.

Why Professional-Grade for Critical Cardiac Response

From Our Medical Facility Battery Analysis: After reviewing 1,200+ AED battery installations across hospitals and emergency services, we've identified the critical performance requirements for cardiac defibrillation equipment where seconds determine survival outcomes.

Critical Medical Applications:

• Hospital Emergency Departments: Emergency rooms, cardiac care units, intensive care facilities
• Emergency Medical Services: Ambulances, paramedic units, first responder vehicles
• Healthcare Facilities: Clinics, surgery centers, dialysis centers, rehabilitation facilities
• Public Safety Programs: Fire departments, police units, corporate medical response teams

Direct Replacement For:

PowerHeart AED Models: 9110, 9210, 9200D, 9141 • Firstsave Survivalink Models: 9200d-2, 9210d-2 • OEM Part Number: 9141-001 Direct Replacement - No adapters, no modifications, no compromises

⚠️ NOT Compatible with PowerHeart AED G3 series models

We've Seen What Happens When AED Batteries Fail

• Critical Response Failure: AED shuts down during defibrillation attempt, leaving cardiac arrest patient without life-saving intervention
• Medical Compliance Risk: Non-FDA approved batteries may violate hospital accreditation standards and regulatory compliance requirements
• Emergency Preparedness Gaps: Generic batteries with inconsistent self-testing create false confidence in AED readiness status

We choose professional-grade accordingly. Because some things can't afford to fail.

Q: "My Cardiac Science AED shows 'Service Battery' but still runs diagnostics. Is immediate replacement necessary?"
A: Yes. The self-diagnostic system detects capacity degradation before complete failure. While it may complete self-tests, the battery cannot guarantee sufficient power for a full defibrillation sequence. We've documented emergency failures within 45 days of first "Service Battery" warnings.

Q: "What's the difference between capacity degradation and complete battery failure?"
A: Capacity degradation occurs gradually - batteries maintain basic functions but lack full discharge capability. Complete failure is sudden power loss. Check installation date: under 24 months suggests environmental stress, over 36 months indicates normal end-of-life replacement cycle.

Q: "Can this 9141 battery work in other manufacturer's AED systems?"
A: No. While the voltage specification may match, Cardiac Science AEDs require specific connector configurations and discharge characteristics. Using in other systems could damage the battery, create unreliable operation, or void medical device certifications. Always use manufacturer-specified batteries for life-safety equipment.

Q: "Why choose Tech Battery Solutions for critical medical batteries?"
A: After 15 years supplying AED batteries to healthcare facilities, we understand medical-grade requirements. We stock only FDA-approved batteries that meet Cardiac Science's exact specifications. Our batteries ship ready for immediate installation and pass diagnostic checks without delays. Plus, we provide technical support based on real hospital deployment experience.
