Yours is not the first nor only case we've heard of this. http://daveinolywa.blogspot.com/2014/11 ... -read.html
was one. There have been others
IIRC, a dealer tech is supposed to do an intentional reset if the big battery is changed. Unfortunately, it seems some unscrupulous folks have been doing this w/o replacing the battery.
IIRC, also during the Phoenix battery degradation debacle, some customer cars were temporarily borrowed by Nissan corporate and at least one came back with the display reset to 12 CBs. It eventually crept back to the original level. I thought I recall reading this. Hopefully someone can confirm my story or tell me I'm wrong.

is one table I've found.
But yeah, being down 3 bars w/a pre-4/2013 battery in a warm/hot climate before the 5 year/60K capacity warranty is up isn't surprising.
I still have all 12 bars on my 5/2013 built used '13 Leaf SV. I'm in a hotter part of the SF Bay Area. As of earlier tonight my stats were these:
odo: 40,340 miles
I am getting closer to losing a capacity bar... sometimes Hx is down to 84.xx%.
