Battery Replacement
Light- & Medium-Duty
A weak battery does not always give warning before it strands a truck. Our factory-trained techs test, inspect, and replace batteries with OEM parts so your light- and medium-duty vehicles start every time.
Quick Answer
A battery inspection checks the case, terminals, and two electrical tests — reserve capacity and cranking output. If either test fails, Truck City Service replaces the battery with an OEM unit installed to factory spec, same day in most cases.
Why Battery Failure Catches Fleets Off Guard

Most batteries fade gradually, not suddenly. By the time a truck fails to start, the battery has usually been under-performing for weeks — costing you a dead-battery call at the worst possible moment.
A battery that starts your truck today can fail tomorrow with zero warning.
“We test reserve capacity, not just voltage. A battery can read fine at rest and still not have enough left to crank a cold engine on a January morning.”
