Enter your EV's original range, current age, and annual mileage to estimate remaining battery capacity and range.
Most EV batteries degrade 1.5-2.5% per year on average, with higher-mileage vehicles and hot climates typically seeing faster decline — this is a general estimate, not a substitute for an actual battery health check.
Most manufacturers warranty EV batteries to retain around 70% capacity at 8-10 years or 100,000 miles, and real-world data generally shows degradation front-loaded in the first couple years before leveling off. This estimate uses typical published fleet averages — actual degradation varies by battery chemistry, climate, charging habits (frequent DC fast charging accelerates wear), and how often the battery sits at very high or low state of charge.
Yes, moderately — frequent DC fast charging generates more heat and stress on cells than slower Level 1/2 charging, and most manufacturers recommend limiting daily reliance on fast charging where possible.
Yes — that range is broadly consistent with published fleet data for most modern EVs over 5-8 years of typical use, and most batteries continue functioning well beyond that point, just with somewhat reduced range.
