erco wrote:Leaf wannabe here. Looking at a 2015 Leaf on a used car lot. Is that possible to still have 12 bars at 42K miles, or has someone tricked the battery? Southern California, hot area. Salesman says the guy was fast charging at both ends of a 50 mile (each way) commute for 2 years.
Any thoughts? TIA.
It is likely that the 12 capacity bars are correct, but that there has been some loss of battery capacity in 2 years and 42k miles. I had 29936 miles on 10/22/2016 (manufactured 01/2015 and purchased 2/7/2015) when I lost the first capacity bar
and anywhere in Southern California (except Death Valley) would have significantly cooler average temperatures than Phoenix. I still have 11
capacity bars at 45095 miles. If you like the car, make your purchase decision with the assumption that the first capacity bar
may drop soon.
The original driver probably took advantage of Nissan's NCTC (no charge to charge) program which allows 30 minutes of DCQC for each charge session for the first 2 years of use without cost. The commute was probably on the freeway so it was necessary to charge at each end (no chance to go 100 miles on the freeway on one charge). Since battery AHr, SOH, and Hx numbers for my 2015 (as reported by Leaf Spy) improve after DCQC and drop after gentle driving, you may see those numbers drop some during the first couple weeks of suburban use and charging at home (especially if trickle charging at 120 volts) but they should stabilize. For example, my commute is 52 miles round trip (26 each way with about 21 on the freeway) and most of my charging is at home using my 30-ampere, 240-volt EVSE. My Leaf Spy numbers will drop temporarily if I drive gently without highway use or charge slower (lower rate at 240 volts or trickle charge at 120 volts), but return to normal after a couple days of normal use. I use DCQC if I need to drive extra miles during the day and my Leaf Spy numbers always improve for a period of time.
