Maxwell Technologies is expanding its ultracapacitor-based Engine Start Module (ESM) product line to class 3 through 6 medium-duty trucks that it has been offering previously to class 7 and 8 heavy duty diesel trucks. The new ESM ULTRA 31/900 provides the following features and benefits:
900 cold cranking amperes (CCA), or a three-second crank;
Reliable starting for diesel engines up to 9.9 liters at temperatures --40°F to 149°F;
Low maintenance operation and life-of-the-vehicle reliability;
Industry standard Group 31 battery form factor for easy integration with battery systems;
Built-in quick charging system (15 minutes or less);
Extended battery life, full compatibility with existing battery systems; and
Four year unlimited warranty.
Maxwell's ESM ULTRA 31/900 assumes the starting responsibility for the truck and effectively eliminates cranking problems that come from weak or discharged batteries. The ESM weighs16 lbs., delivers reliable starts and allows extensive use of lift-gates and buckets while the engine is off without fear of the truck not starting.
The ESM ULTRA 31/900 is a no-acid, lead-free energy storage solution that weighs less than one-fourth of the Group 31 lead-acid battery it replaces. It stays fully charged even when the truck's lead-acid battery is as low as 9.5V.
