EV Battery Degradation Guide
Battery degradation is normal in EV ownership, but charging and storage habits can slow range loss.
What affects degradation
High heat, sitting at 100 percent, frequent high-power DC charging and deep discharge can increase battery stress.
LFP and NMC chemistries can have different charging and calibration recommendations.
Healthy habits
Moderate daily charge windows, reasonable temperatures and preconditioning when needed help support battery health.
Charging high before a trip is normal; the concern is leaving the battery high for long periods.
Reading range loss
Displayed range is not a service diagnosis on its own. Tires, weather, driving style and software updates can change estimates.
For consistent tracking, combine the battery health calculator with the degradation tracker.
