'13 Leaf SV (Leased) - Leased 34 months. Drove 41K miles. All 12 bars intact when returned car. Mostly charged to 80% between midnight and 5a.
'16 Leaf SV (Purchased - Manufactured 12/15) . Typical charging pattern is to try and charge to 75-90%. Charging typically happens between midnight and 5a.

The 11/10/2016 was actually a test for a friend. He wanted to ensure he could get a good read before testing used Leafs.
The 11/26/2017 reading is my test to make sure I could get the readings on my phone.
Pretty happy that in over a year my SOH only dropped 4%.
On Tuesday I plan on charging the car to 100% SOC and taking another set of readings which I will report back into the thread.
Here's my state from today from the Lite version of LeafSpy
Ahr = 70.85
SOH = 89%
V = 395.32
Hx = 83.71%
ODO = 24414
QC = 7
L1/L2 = 1205
SOC = 97.8%
Anyone care to comment on what they see within those stats?
The only change we'll make is to charge to 100% SOC when we know we may be at risk of dropping to <25% during the days driving. In the past we focused on holding near 80% SOC and if you got home at 5% SOC so be it. One other change will be, if we get home with <25% SOC to charge it to 30% - then finish the charge off during the evening hours when rates are less (off peak charging).
there is very little risk to charging to 100% during cold weather. Degradation after A YEAR is only 6% @ 32ºF verses 2% @ 40% SOC (general Li guidelines only here) so an overnight or even a few days? Not something you should do but if it happens, its nothing to lose sleep over. We also have to keep in mind, lower Winter range so charging to a higher SOC is not only minimally bad thing to do, its simply being prepared for the worst.
Its Summer you need to worry about and yeah, it will be more than warm enough.
The reality appears to be what happened before you got the car. 10% down on day one it would seem. Look at the stats of your 2013 and I think time on the lot is your main factor.
We purchased the '16 Leaf in April 2016. Took first Leaf Spy readings on 11/10/2016 - after driving the car almost 10K miles - disappointed with the 7% SOH drop in only 7 months. However, my perspective is that after 19 months of ownership, 24K miles of driving that I wish my SOH was higher than 89% but can't be too disappointed compared to some of the other stories I have read.
