There are a few clear warning signs that point to a failing battery. You might notice the engine cranking slower than usual, headlights looking dim or flickering, or a battery warning light appearing on your dashboard. If your Chevy is three years old or more and you're seeing any of these symptoms, it's time to bring it in for a conductance test at our Rochester service center.

All batteries wear down with time, but certain conditions accelerate that process. Infrequent driving allows the battery to slowly discharge on its own. A fully discharged battery can freeze at 32 degrees Fahrenheit, which causes permanent internal damage. Extended exposure to high heat also breaks down battery chemistry. And improperly connected accessories or aftermarket electronics can put excessive drain on the entire system.

The most effective step you can take is having your Bob Johnson Chevrolet Rochester Certified Service technician run a conductance test each time you come in for an oil change. This test measures the battery's real ability to deliver current and gives you a clear reading on how much life remains. It's a quick process, typically just a few minutes, and it saves you the hassle of dealing with an unexpected no-start situation down the road.

Most car batteries hold up for three to five years under normal driving conditions. In Rochester's climate, where we deal with harsh winters and warm, humid summers, battery life tends to lean closer to the three-year mark. We recommend annual battery testing once yours passes the three-year point, so you're never caught off guard by a sudden failure.

batteries carry an 18-month warranty, ACDelco Gold batteries are covered for 30 months, and ACDelco Gold AGM batteries include 36-month coverage. Our service advisors will walk you through the warranty details for each option when you schedule your battery service appointment.

We welcome walk-ins for battery testing during our regular service hours. That said, booking an appointment ahead of time helps us reduce your wait time and gives our technicians the chance to address any additional service needs during the same visit.
