– Over 90% of survey participants have not lost a capacity bar.

– Over 75% believe they have lost no more than a few miles of range.
– Those who have lost capacity bars are almost all in hot climates.
– Not all cars in hot climates have lost capacity bars.
– Factors other than miles and climate don’t have a big effect on capacity.
– In cool climates, a LEAF can go 60,000 miles before losing a capacity bar.

The full report with more detail, information on capacity loss in different climates, analysis of factors other than mileage and climate on battery capacity, and how to interpret Nissan’s battery report is available here:

We’re interested in continuing to track LEAF battery health. Please send in another report on your vehicle in six months, whenever you lose a capacity bar, or when you just want to show how many miles you’ve driven.
