Year-around Battery Performance Testing Service
Your Cadillac vehicle’s battery stores and supplies the electricity from the alternator when the engine is running. The battery provides the voltage to start the engine but then powers the accessories when the engine is not running. Intense cold in winter and heat in summer will help wear your battery down faster. At Napleton Cadillac of Libertyville, we are here to help you monitor your battery’s performance year-around with Battery Performance Testing Service.
