Claiming high mileage doesn't
Claiming high mileage doesn't hold water with me. Steve Marsh in the Pacific NW is putting 40,000+ miles per year on his leaf and has experienced minimal battery deterioration, certainly nothing like what is being reported in Arizona.
If Nissan told me high miles In a hot climate is bad but elsewhere not so much, I'll be willing to swallow that one.
The biggest factor that appears to be in force is the desert heat.
I drive 13,000 miles a year so should see results close to the losses expected. But I don't know what to expect! Is Nashville average, above average or below average climate for battery degradation. We now know those in Arizona can expect an additional 4% loss over 5 years according to Nissan. Less than 1% per year sounds 'normal' to me. Shame that the reports and tests don't support this normality. I wouldn't be suprised to see Nissan revising these estimates as years roll by.
