GoKawiilHow EV owners can tell when battery degradation, not weather, is cutting range
EV batteries naturally lose some usable capacity over time, with the Department of Energy estimating a 12-to-15-year lifespan in moderate climates and 8-to-12 years in harsher ones. A 2026 Geotab study of more than 22,700 vehicles across 21 models found average yearly degradation of about 2.3 percent, though results vary widely by car and driving conditions.
