How does the size of the 8Z compare to equivalent lead-acid starting options?

The 8Z is 75% smaller than equivalent lead-acid starting options.

Does the 8Z come with a full warranty?

Yes, the 8Z has a 10-year full warranty that eliminates regular battery maintenance.

How are ongoing expenses impacted with the 8Z?

With the 8Zs long life and no maintenance, expenses like truck rolls and electrolyte top-ups are cut.

Is it safe to air ship the 8Z?

Yes, 8Zs are safe for air shipping as the high performance NiZn batteries contain no hazardous materials.

Are there lower emissions with the 8Z?

Yes, there are approximately 96% lower lifetime carbon emissions.

What are the increased efficiencies with the 8Z?

The 8Z is more energy efficient to manufacture, transport, and recycle.

How is labor impacted?

There is less labor - no need for regular replacement or periodic watering.

Is the unit preassembled?

Yes, the SuperTorque 8R is preassembled and tested in our Colorado facility.

Overview

Solves Genset Starting Problems

SuperTorque 8Z Engine Starting System solves the #1 problem with emergency generators: starting battery failure. Unless lead-acid starting batteries on gensets are replaced every one to three years, they fail suddenly, without warning. Even if replaced this often, they sometimes explode.

75% smaller than comparable lead-acid options (including charger), the 8Z's long life and no maintenance cuts ongoing costs of truck rolls and electrolyte top-ups. Well proven as a data center UPS, it's a sustainable choice with no hazardous materials at 96% lower lifetime GHG emissions.

Assumptions:
1. Lead-acid batteries modeled at $275 each.
2. Labor for battery replacements based on $125/hour, 2-person team, four-hour job ($1000 total).
3. Lead-acid battery maintenance includes check and water every six months. Assume 1 hour @ $125/hr ($250/year).
4. The Ni-Zn battery is maintenance-free. It requires no electrolyte check or top-up.
