DATASHEET ULTRA 31/900 ENGINE START MODULE PUT AN END TO JUMP-STARTS WITH THE ENGINE START MODULE FROM MAXWELL Whether the medium duty trucks in your fleet are step vans, package cars, utility vehicles, lease/rental trucks or food & beverage delivery trucks, Maxwell has the solution to your jump-start and stranded vehicle headaches. Because of increased loads in today’s trucks - such as lift-gates, radios and lights, your batteries frequently do not have the power needed to start your engine.* Don’t leave starting to batteries. The ULTRA 31/900 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 – potentially for the life of your truck. Replace a battery or add the Engine Start Module to a Class 3-6 diesel truck for reliable starting from -40°F to 149°F (-40°C to +65°C) FEATURES & BENEFITS* Engine start reliability 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 8 minutes (Initial charge is 15 minutes or less) Provides 900 CCA (3 second crank) Long life - limited 4 year warranty Assembled in the USA Maxwell Technologies ULTRA 31/900 Engine Start Module *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.

Disconnect cable(s) connecting the batteries to the starter, and remove one battery. 1. CCA = 2. Install the ULTRA 31/900 and connect the existing cable(s) from the Starter Solenoid to the S+ terminal of the ULTRA 31/900. 3 2. Peak Power = 3. Connect Cable from the primary Battery Positive terminal to the B+ terminal of the ULTRA 31/900. 4. Connect the negative battery cable to the B- terminal of the ULTRA 31/900. 5. Initial Charge - The ULTRA 31/900 takes up to 15 minutes for an initial charge (8 minutes thereafter). 6. See the ESM Installation Video at: http://www.maxwell.com/esm under the Features tab.
