How Many Years Does a Car Battery Typically Last?
1 Answers
Car batteries typically last 2 to 4 years. Conventional car batteries use lead-acid technology with a cycle life of approximately 200 to 500 charges, resulting in a service life of about 2 to 4 years. Vehicles equipped with automatic start-stop systems utilize specialized batteries that offer higher cycle durability - ranging from 400 to 800 charges - extending their lifespan to 4-6 years. New energy vehicles employ lithium batteries with superior longevity, lasting 5 to 8 years. Most batteries operate under partial charge/discharge conditions during normal vehicle operation, which effectively prolongs cycle life. The specified cycle life refers to complete discharge-charge cycles; standard automotive batteries can endure about 200 full cycles.
