Most car batteries last 3 to 5 years, depending on climate, driving habits, and vehicle age. Warning signs include slow engine cranking, dim headlights, clicking sounds when turning the key, or corrosion around battery terminals. A professional test reveals whether your battery needs replacement before it leaves you stranded.

Cold weather is especially hard on batteries, so fall and winter are common replacement times. A fresh battery ensures reliable starts and stable electrical power for all your vehicle's systems.
