DATASHEET ULTRA 31/1800 & ULTRA 31/900 ENGINE START MODULE JUMP STARTS DON’T HAVE TO BE A WAY OF LIFE. EFFECTIVELY ELIMINATE THEM WITH THE MAXWELL ULTRACAPACITOR ENGINE START * MODULE (ESM) Starting reliability in today’s trucks is more critical than ever. Whether you own one truck or a fleet, you can’t afford down time due to dead or discharged batteries. The Maxwell Engine Start Module (ESM) makes jump-starts a thing of the past. Don’t leave starting to batteries. The Engine Start Module from Maxwell Technologies provides high power for hundreds of thousands of starts. With a four-year non pro-rated warranty it has the durability to start your truck consistently. Replace a battery or add the Engine Start Module to a Class 3-8 diesel truck for reliable starting from -40°F to +149°F (-40°C to +65°C) ULTRA 31/1800 Engine Start Module For Heavy Duty (Class 7 - 8) Trucks ULTRA 31/900 Engine Start Module For Medium Duty (Class 3 - 6) Trucks FEATURES & BENEFITS* Replaces one Group 31 battery No lead. No acid. Improves overall system power performance Shock & vibration resistant Built-in overcharge protection Low total cost of ownership Cold weather reliability down to -40oF (-40°C) Faster cranking Industry standard BCI Group 31 form factor Recharges fully in less than 15 minutes (Initial charge is 30 minutes or less) Provides 900-1800 CCA1 4-year non pro-rated warranty Assembled in the USA *Lead acid batteries still power ECM/ECU. Results may vary. Additional terms and conditions, including the limited warranty, apply at the time of purchase. See the warranty details for applicable operating and use requirements.
