The SuperTorque® 8Z Engine Starting System from Stored Energy Systems is designed to eliminate the most common failure point in emergency generators: starting batteries. Traditional lead-acid batteries often fail without warning and require frequent replacement every 1–3 years. SuperTorque® 8Z solves this problem with a safer, longer-lasting, and more powerful alternative.
At the core of the system is a high-performance nickel-zinc (NiZn) battery, delivering exceptional starting power, long service life, and unmatched reliability. With a full 10-year warranty, integrated smart charging, and zero maintenance requirements, SuperTorque® 8Z provides peace of mind for critical power applications.
Why Choose SuperTorque® 8Z
Eliminates starting battery failure – Designed specifically for genset reliability
10-year full warranty – No more frequent battery replacements
More power, less space – Up to 75% smaller than comparable lead-acid systems (including charger)
Maintenance-free operation – No watering, testing, or routine service required
Safer chemistry – No hazardous materials; stable NiZn technology
Air shippable – Simplifies logistics and deployment
Lower total cost of ownership – Over 50% savings compared to lead-acid over 10 years
Sustainable solution – Up to 96% lower lifetime GHG emissions vs. lead-acid
Advanced NiZn Battery Technology
The SuperTorque® 8Z utilizes a super high-rate nickel-zinc battery, proven in demanding applications like data center UPS systems. Unlike lead-acid batteries, NiZn maintains strong voltage even at lower states of charge, ensuring consistent engine cranking performance when it matters most.
Key Advantages of NiZn:
High-rate discharge capability for powerful engine starts
Stable voltage throughout discharge cycle
Longer service life with no degradation from deep cycling
No risk of sudden catastrophic failure common with lead-acid
Integrated Smart Charging System
Each SuperTorque® 8Z system includes an embedded MicroGenius 2 charger, factory-installed and optimized for NiZn battery chemistry.
Universal AC input: 100–240V, 50/60 Hz
Plug-and-play installation (IEC connector or hardwired)
Up to 93% efficiency
Less than 3 watts idle consumption
No separate charger installation required
More Power in Less Space
A single 24V SuperTorque® 8Z system, roughly the size of one 12V 8D battery, can replace:
Up to four 8D lead-acid batteries
A separate premium charger
This compact footprint frees up space while simplifying system design and installation.
Engine Starting Capabilities
SuperTorque® 8Z is engineered to handle demanding generator applications:
Supports diesel engines up to 70 liters displacement (dual starter configurations)
Maintains strong voltage during the critical locked rotor phase (~200 ms)
Compatible with typical ECU voltage tolerances on 24V systems
Sustainability & Safety Advantage
SuperTorque® 8Z is the environmentally responsible choice for generator starting:
96% lower lifetime greenhouse gas emissions vs. lead-acid
No hazardous materials
No electrolyte handling or disposal concerns
Lightweight and energy-efficient to manufacture, transport, and recycle
Lower Total Cost of Ownership (TCO)
Traditional lead-acid batteries come with hidden costs:
Replacement every 1–3 years
Routine maintenance (inspection, watering)
Labor-intensive service calls
SuperTorque® 8Z eliminates these costs entirely with:
10-year maintenance-free operation
No replacement cycles
Reduced labor and downtime
Result: More than 50% cost savings over a 10-year lifecycle
Applications
Emergency standby generators
Data centers
Healthcare facilities
Telecommunications sites
Industrial and commercial backup power systems
