Engineered for Mission-Critical Defibrillation Systems. Your Zoll R Series, E Series, or AED Pro delivers advanced cardiac interventions requiring instant readiness and sustained power delivery. The SurePower lithium-ion battery provides 5.8Ah capacity with intelligent runtime indicators showing "30 minutes remaining" - eliminating guesswork when patient survival depends on equipment reliability.

As battery specialists since 2010, we've supplied over 3,200 Zoll SurePower batteries to hospitals, EMS agencies, and emergency departments where defibrillator failure is unacceptable. This OEM lithium-ion pack features four times the energy density of traditional chemistries, delivering 400+ charge cycles with on-board memory tracking maintenance history - designed for healthcare professionals managing advanced life support systems where consistent performance saves lives.

Why SurePower Lithium-Ion for Advanced Life Support Systems

From Our Hospital Equipment Analysis: After tracking 850+ AED battery replacements across critical care environments, we've identified why Zoll's SurePower technology outperforms traditional battery chemistry in high-stakes medical applications.

• Runtime Indicators: Displays "30 minutes remaining" instead of "25% capacity" - eliminates interpretation errors during extended resuscitation efforts
• On-Board Memory System: Retains complete maintenance and usage history for regulatory compliance and predictive maintenance planning
• Automatic Calibration: Self-adjusting accuracy ensures runtime predictions remain precise throughout battery lifespan
• Enhanced Energy Density: Four times greater capacity-to-weight ratio than NiCd chemistry - keeps pace with advanced defibrillator features without size increase
• Superior Capacity Retention: Minimal degradation over charge cycles reduces replacement frequency and total cost of ownership

Proper Maintenance Protocol (Non-Negotiable):

• After Each Use: Recharge immediately following any deployment - partial charges do not harm lithium-ion chemistry
• Monthly Preventive Charging: Connect to charger even if unused - maintains calibration accuracy and prevents deep discharge damage
• Charge Cycle Documentation: Maintain Battery Recharge Record for regulatory compliance and predictive replacement planning
• Temperature Compliance: Only charge within 59°F to 95°F range - charging outside this window reduces capacity by 20-30% permanently

Warning: Failure to follow monthly charging protocol voids warranty and can reduce battery life by 40-50%. Set calendar reminders for maintenance charging.

SurePower Batteries Excel in Critical Healthcare Applications:

• Hospital Emergency Departments: Trauma centers, cardiac catheterization labs, intensive care units requiring Zoll R/E Series advanced monitoring
• Emergency Medical Services: Paramedic units, critical care transport, air ambulance services using AED Pro with CPR feedback
• Cardiac Care Facilities: Electrophysiology labs, cardiac rehabilitation centers, specialized heart hospitals with Zoll equipment
• Military and Tactical Medicine: Field hospitals, combat medic units, disaster response teams requiring reliable advanced life support

Compatible Zoll Defibrillator Models:

R Series: All R Series ALS defibrillator/monitor configurations
E Series: All E Series models including E Series with Rectilinear Biphasic technology
AED Pro: All AED Pro configurations with Real CPR Help technology
Part Number: Direct replacement for Zoll OEM #8019-0535-01

We've Seen What Happens When Critical Care Batteries Fail

• Unexpected Equipment Downtime: Battery failure during cardiac arrest eliminates advanced monitoring capabilities, forcing downgrade to basic defibrillation when comprehensive data could improve outcomes
• Interrupted Treatment Protocols: Mid-procedure power loss during extended resuscitation disrupts CPR feedback systems and waveform analysis critical for clinical decision-making
• Regulatory Compliance Gaps: Missing maintenance records from battery memory loss creates documentation deficiencies during Joint Commission surveys and equipment audits

We choose OEM SurePower batteries accordingly. Because advanced cardiac care cannot afford equipment compromises.

Q: "My Zoll shows 'Calibrate Battery' message after installation. Is something wrong?"
A: No, this is normal. The SurePower's on-board memory needs 2-3 minutes to synchronize with your defibrillator after installation. Complete the automatic calibration cycle without interruption. If the message persists beyond 5 minutes, verify the battery is fully seated and latched - 90% of persistent calibration errors result from incomplete latch engagement.

Q: "How accurate is the runtime indicator during actual emergency use?"
A: Based on our field data from 3,200+ installations, the runtime indicator remains within 5-8% accuracy throughout the battery's service life when monthly charging protocol is followed. During extended resuscitations (20+ minutes), customers report the countdown provides critical decision-making data about when to switch to backup equipment - significantly more useful than percentage indicators that require mental calculation under stress.

Q: "Can I skip monthly charging if the battery shows full capacity?"
A: No. Monthly charging maintains calibration accuracy in the on-board memory system. Skipping charges causes the runtime indicator to drift from actual capacity - within 6 months of irregular charging, accuracy degrades to 15-20% error. This defeats the primary advantage of SurePower technology. Set non-negotiable calendar reminders for the first of each month.

Q: "What's the total cost difference versus cheaper aftermarket options?"
A: While genuine SurePower costs more initially, our 5-year tracking shows 35-40% lower total ownership cost. Aftermarket batteries lack the on-board memory and runtime indicators, require replacement every 2-3 years versus 4-5 years for OEM, and create regulatory documentation gaps that cost $200-500 in administrative time during equipment audits. For critical care equipment, genuine OEM is the only defensible choice.

Q: "Why choose High-Tech Battery Solutions for this purchase?"
A: After 15 years specializing in medical equipment batteries, we understand Zoll's maintenance requirements. We verify every SurePower battery is within 90 days of manufacturing date before shipping - older stock batteries lose 10-15% capacity from shelf time. Plus, our specialists provide maintenance protocol guidance based on actual hospital equipment management experience, not just spec sheets. We include documentation templates for regulatory compliance.
