Maxwell Cranks Up ESM For Medium-duty Trucks

March 10, 2014 By: Trucking News Staff Tags: Equipment, News

Maxwell Technologies has expanded its ultracapacitor-based Engine Start Module (ESM) product line to provide the same benefits to Class 3 through 6 medium-duty trucks that it already offers to Class 7 and 8 heavy-duty diesel trucks.

Consistent with the current ESM product, 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
  • 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 product delivers the quick-burst power trucks need to crank their engines in extreme cold.

At 16 pounds, the new ESM is rugged and lightweight, delivering reliable starts and allowing 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.
