or about .30% per year. Now should a Leaf owner overly focus on what charging cycle is optimum to minimize degradation
or on what factors related to battery heat should be of more concern, e.g. excessive QC on a hot day?
A rapid cycle test where you go through 2500 cycles in 7 months is NOT the same as your typical usage cycle where you will leave the battery sitting at 100% for extended periods of time, not to mention at temperatures much greater than 20C.
Both of those factors will make the difference significantly larger in real life.
