About Battery Degradation
All EV batteries lose capacity over time due to chemical aging. Most modern EVs retain 80-90% of their original range after 100,000 miles.
- Calendar Aging: Batteries degrade even when parked, especially in hot climates.
- Cycle Aging: The more you drive and charge, the more wear on the cells.
- Fast Charging: Excessive heat from DC fast charging can accelerate wear.
- State of Charge: Keeping the battery between 20% and 80% extends life significantly.
