Just posting here to keep records, along with others with a similar year, etc.
2015 Leaf SL -- purchased in late Feb 2018, with 33k miles, 12 bars.. I just lost bar #1 at 36636 miles.
Just today I've ordered an OBDII device so I can run LeafSpy and get better stats to post, etc. Should be here by Sunday.
I've used an L3 charger about 8 times so far with this car, most of which were on a road trip I took to Seattle and back. I've got a Bosch L2 charger in my driveway that I've been using just over a month. Before that it was mainly overnight L1 charging. From what I've read, this shouldn't have much of an impact on my battery life. Near as I can tell, this was a northern California / SF car before it came to my neck of the woods.
