BATTERY FAQs

Signs of wear may include slow engine cranking, weak or dim lights, or an illuminated dashboard warning light.

Batteries wear out over time, but there are also issues that can impact battery failure. For example, infrequent start-ups, discharged batteries freezing at 32 degrees Fahrenheit, hot temperatures and improperly connected accessories.

The best thing that you can do is have your Thornton Chevrolet Certified Service technician perform a conductance test on your battery when you get your oil changed. This helps to monitor the status of the battery and helps prevent you from being in a situation where your vehicle won’t start.
