A dead or failing battery will stop your truck cold at the worst possible time. Whether you are parked at a truck stop, a loading dock, or mid-route somewhere in the Sacramento area, Capital Diesel dispatches a diesel mechanic directly to your location to diagnose and resolve the issue onsite. No tow, no shop wait, no unnecessary downtime.
Our mobile truck battery service covers everything from dead and weak batteries to charging system failures and corroded terminals. Our technicians arrive fully equipped with professional diagnostic tools and high-quality replacement batteries to handle the job at your location. We test your battery, starter, and alternator to make sure the replacement solves the root problem and does not leave you stranded again a week later.
Capital Diesel serves Sacramento and the surrounding area within a 60-mile radius, including West Sacramento, Elk Grove, Roseville, Rocklin, Folsom, Davis, Woodland, Citrus Heights, North Highlands, and Rancho Cordova. We work on all major commercial truck brands including Kenworth, Peterbilt, Freightliner, Western Star, Volvo, International, Mack, Hino, and Isuzu. Fleet operators can also contact us to schedule routine battery inspections as part of a preventive maintenance program.
