I can hold out hope that my 2015 battery capacity does even better I suppose. I have yet to do any Denver trips in winter but really want to try out the Arapahoe quickcharge now that it seems stable.
How did your trip back from DIA go? The return trip from Denver in winter (even mild winter days) is what has me scared to try.
I still get no worse that 65 miles effective range. My normal commute is only 27mi but occasionally I do double that in snow and cold and still manage on no more than 73% battery. I use heat on lowest manual setting and eco (if at all) which is enough to take the chill out of the car and keep the windows defrosted without killing range.
So, to answer the question, the return trip went fine. I stopped by Arapahoe Nissan and got a quick charge. Minimal heater use and hypermiling got me home. Of course, the trips takes a lot longer for those reasons, so it's not for everyone. If the QC was down my backup plan was to get to Castle Rock and do a two-hour L2 top-off at Walgreen's while using the WiFi at the next door Panera. (Plan C would have been the Castle Rock L2 chargers at the hospital. Plan D would have been call family to pick me up in Castle Rock. After a while with any non-Tesla EV you learn that long journeys require multiple contingency plans for charging.)
Nissan is completely silent on any changes they've made to the battery over time except to say that 2015s have the heat resistant battery. However, metrics collected here and elsewhere suggest that the battery changed in 2013 and it performs and lasts better than the previous one. I would be very surprised if your 2015 doesn't retain battery capacity much better than our 2012 has done. However, our 2012 is probably doing better than most LEAFs of a similar age in Denver because we live in a cooler location (about 10F lower temperatures on average than Denver), and for 2012 LEAFs heat was the biggest factor in battery degradation.
Another advantage your 2015 has is the ability to leave climate control on while turning off the resistance heater. This was introduced as a feature in 2013 and reduces the amount of heater time you need for defrosting.
