Heavy-Duty 12V & 24V Commercial Jump Start Services
Starting a Class 8 diesel engine with multiple heavy Group 31 commercial batteries demands vastly more power than passenger car jumper cables can deliver. Cold mornings and overnight sleeper accessory usage can quickly drag battery banks down below the cranking threshold required for high-compression diesel pistons. RoadRunner Road Services carries industrial high-amperage boost chargers capable of supplying instantaneous cranking amperage to both 12-volt and 24-volt electrical systems.
Before leaving, our technician runs an alternator load test and checks battery state of health to verify that your charging circuit is holding proper voltage under load.
