Batteries

The advanced batteries in electric vehicles are designed for extended life but will wear out eventually. Several manufacturers of electric vehicles are offering 8-year/100,000-mile battery warranties. Predictive modeling by the National Laboratory of the Rockies indicates that today’s batteries may last 12 to 15 years in moderate climates (8 to 12 years in extreme climates). In addition to climate, other factors impacting battery life include driving and charging patterns, battery cell chemistry and design, and the vehicle-battery-environment thermal system

 

Check with your dealer for model-specific information about battery life and warranties. Although manufacturers have not published pricing for replacement batteries, some are offering extended warranty programs with monthly fees. If the batteries need to be replaced outside the warranty, it may be a significant expense. Battery prices are expected to continue declining as battery technologies improve and production volumes increase
