How long do electric car batteries last?
By LarryLeoUpdated October 4, 2026
Short answer
Many are designed to last the life of the vehicle; most automakers warranty them for at least 8 years / 100,000 miles.
EV batteries gradually lose capacity over time rather than failing suddenly. Warranty terms vary by brand and state, so check the specific coverage and capacity threshold for any car you're considering.
Managing heat, avoiding sitting at 100% for long periods, and moderating fast-charging frequency can help preserve capacity.
