Understanding Battery Degradation
EV battery degradation is influenced by many factors including age, mileage, charging habits, and climate. Frequent DC fast charging, extreme temperatures, and deep discharge cycles can accelerate degradation. Most manufacturers warranty batteries to 70-80% capacity for 8 years or 100,000 miles. To maximize battery life, charge to 80% for daily use, avoid extreme temperatures, and limit fast charging when possible.
