I leased my SL back at the end of March 2013, and now have about 14,350 miles on it. I live in a part of S. California that can get hot, although not all of the time - San Dimas - right on the border of Los Angeles and San Bernardino counties (on the LA side). We got probably around 30 - 35 days in the last 12 months that were over 90, maybe about 10 - 15 of which were over 100. The car is either kept in my non-insulated garage or in an outdoor parking lot during the day, and is pretty much always in my garage overnight. Since the climate here is a bit warm (certainly not as warm as some places, but warm enough), I thought it might be a good idea to see how my battery is faring, and ordered and OBD II device and downloaded LeafSpy light.
I thought by now, after about 14 1/2 months and 14,350 miles, I would probably be at somewhere around 88% - 90% SOH and Hx. I have not noticed any reduction in range, but I don't tend to push it, so I thought it was probably there, I just hadn't noticed because I'm not driving the car to it's max range a lot. I charge to 80% most days, but have no problem charging to 100% when needed, and I tend to let it sit at 100% for several hours before driving to take best advantage of the TOU rate from SoCal Edison. I am maintaining a lifetime mi/kwh average of 4.5, according to the dash.
What I got surprised me a bit, in a good way. Based on all of the capacity loss talk, I'm just not sure if it's unusual, or better than average. Screenshot attached.
