Most car batteries last three to five years. Signs it's time to replace yours include slow cranking, dimming lights, or corrosion on the terminals. Cold weather can shorten battery life, so winter checks are smart. Castle Chevrolet of Villa Park stocks genuine Chevrolet batteries and can test your current battery at no charge to see if replacement is needed. Our Service team will also clean terminals and ensure your charging system is working properly. If you notice any warning signs, call (630) 279-5200 to schedule a battery inspection.
