I'm not sure why this is the case, but there seems to be a perception among many Florida residents that we are immune from the battery degradation problems Texas and Arizona LEAF owners are experiencing just because we rarely see high temperatures above 100F.
It isn't the extreme high temperatures that are going to kill our LEAF's batteries, it's the persistent warm temperatures.
Degradation doesn't just shut off at temperatures below 80F. It merely slows down. So, while other parts of the country are enjoying temperatures in the 40s, 50s and 60s (or even colder) during the fall, winter and spring, Florida is still basking in the 70s and 80s.
We've already had one South Florida LEAF owner report a one-bar loss at only a little over one year and 16,000 miles. If you are a Florida resident, and you are racking up 20,000+ miles a year, your battery is going to degrade very quickly no matter what you do.
