Battery Testing & Replacement
Light- & Medium-Duty
A dead battery does not wait for a good day. We test, diagnose, and replace batteries for work trucks, vans, and fleets, and we check the charging system so a new battery does not die the same way the old one did.
Where can I get a truck battery tested or replaced in Greeley, CO?
Truck City Service at 1415 1st Ave in Greeley tests, diagnoses, and replaces batteries for light- and medium-duty trucks, vans, and fleets. We check charge capacity and the charging system, not just the battery, so the new one lasts. Factory-trained technicians handle removal, safe disposal, and installation in one visit, Monday through Friday, 7:00 AM to 6:00 PM.
A Battery Rarely Fails Without Warning
A truck battery holds a surprising amount of electricity, and it spends most of its life quietly losing capacity before a cold morning finally exposes it. By the time a truck won’t start, the battery has usually been weak for weeks.
“We see it most on trucks that sit overnight in a lot without a heated bay. The driver notices the engine cranks a little slower for a few days, then one morning it just doesn’t turn over. A load test two weeks earlier would have caught it.”
Sierra, Service Advisor, Truck City Service, Greeley CO
That’s why we test the whole electrical system, not just the battery. A bad alternator or a corroded ground strap will kill a brand-new battery in weeks. A battery check is also part of our medium-duty maintenance service, so it rarely needs to be a separate trip. If your trucks run as a group, our fleet management program tracks battery age and test results across every vehicle so nothing gets found the hard way.
Battery & Charging System Services
Battery Load Testing
We measure charge capacity under load, the same test that separates a battery that’s fine from one that’s about to leave you stranded.
Charging System Inspection
Alternator output, belt condition, and connections all get checked. A battery is only as good as the system that keeps it charged.
Battery Replacement
Old battery removed and disposed of properly, new one installed and tested before you drive off, with OEM and quality aftermarket options in stock.
Light-Duty Service
Corroded terminals and worn cables cause slow cranks and intermittent no-starts that look like a bad battery but aren’t. Covered as part of light-duty maintenance visits.
Parts & Accessories
Our parts department stocks batteries sized for work trucks and vans, not just passenger cars.
Fleet Battery Management
Battery age and test results tracked across your whole fleet, so replacements happen on your schedule, not the side of the road.
Battery Facts Worth Knowing
| What To Check | Spec Or Interval | Why It Matters |
|---|---|---|
| Battery age | Test at 3 years, replace by 4-5 | Most batteries lose meaningful capacity well before they fail outright. |
| Load test result | Should hold rated CCA under load | A battery that reads full voltage at rest can still fail under a cold start. |
| Alternator output | 13.5 to 14.8 volts running | Outside this range, the battery is either undercharged or overcharged, and either one shortens its life. |
| Terminal condition | Clean, tight, no corrosion | Corrosion adds resistance, which reads like a weak battery even when the battery is fine. |
| Cold weather check | Before first hard freeze | Cold cuts cranking power. A battery that starts a truck at 60 degrees may not at 10. |
Intervals are general guidance. Duty cycle, idle time, and how the vehicle is parked overnight all move them, and our advisors can set a schedule around how your trucks actually run.
Signs Your Battery Needs Attention
- The engine cranks slower than it did a week ago.
- Dashboard lights dim when you start the truck.
- The battery warning light is on.
- You’ve jump-started the vehicle more than once this month.
- The battery case looks swollen or corroded at the terminals.
- The vehicle sits for days at a time between routes.
