Battery Load Testing

Truck batteries are primarily responsible for powering the starting system, but they also supply energy to all electrical components. When they aren’t operating correctly, everything from cab light outages to complete system failure can occur. It’s important to maintain battery health in each vehicle to keep your fleet running efficiently. Parasitic loads draw energy from the batteries that the vehicle can’t replace — usually because it’s turned off or idling. Left uncontrolled, parasitic loads can deeply discharge batteries and prevent trucks from starting. Testing in our shop can confirm the presence of a parasitic load and our mechanics can locate the source and resolve the issue.
