Stay Cool Without Idling Your Truck
Before: The Cost of Staying Cool
Idling burns fuel. Summer heat makes rest harder. As regulations change, fuel prices rise, and summer temperatures climb, traditional idling becomes an expensive way to stay comfortable. With 1,800 hours of annual idling, $4.21 per gallon diesel, and overnight AC use, drivers can spend about $7,500 per year on fuel.
After: A Smarter Way To Stay Cool
A LiTime group 31 truck LiFePO₄ battery solution can reduce annual operating costs and help drivers save around $6,000 per year by reducing engine idling, fuel consumption, and unnecessary expenses. LiTime keeps your AC running while helping you save fuel, reduce costs, and create a more comfortable rest experience every night.
