My battery was replaced under warranty on June 20, 2017. The stats at that time were:
I took a reading today and here is where I am almost two Georgia summers later.
Overall, no noticeable degradation. There was no LEAFspy in 2012, so I can't say how this compares to my original battery. I lost my fourth bar at 42.994 AHr and 48,960.9 miles. The losses thus far work out to about 0.28 AHr/month.
