Maxwell 12-Volt Heavy Duty Engine Start Module Ultracapacitor Ultra 31/1800
The Maxwell ESM is by far the leading ultracapacitor-based engine starting product on the market today and offers unmatched capability in truck starting.
Today’s trucks demand more energy from batteries than ever before, and batteries alone are no longer keeping up. To solve the frustrating problem of discharged batteries that can’t start the truck, fleet managers and operators are turning to ultracapacitor engine start technology for Class 7–8 trucks. The Maxwell ESM takes over engine cranking for trucks with engines up to 16 liters in displacement and delivers faster cranking with quicker starts. Unlike a battery, which is susceptible to extreme cold and hot temperatures, our ultracapacitor-based ESM performs down to –40°F and up to +149°F (–40°C to +65°C).
