2018 Chevrolet Bolt EV Battery

Most 12‑volt batteries last 3–5 years, and Utah’s hot summers and cold winters can push lifespan toward the lower end of that range.

On the Wasatch Front, temperature swings and frequent short trips are hard on a 12‑volt battery in a 2018 Chevrolet Bolt-Ev. If your vehicle is parked outside, driven infrequently, or frequently used for short errands, plan on testing the battery annually after year three. You can schedule service for a quick health check.
