I should be so lucky! At 13K on a 2013, my cap is 55.6 Ahrs. Expect the 1st bar loss at 52-53 Ahrs and
at about 20-24K miles. Started at about 60.5 Ahrs.

Not everybody is using the car the same way and it is fine.

In my case I am not using much the heater when driving to preserve range.
But what do I know, Quebec is not that cold ;)
Image I agree with you. Unlike air density and other friction factors (cold tire rolling resistance) and weather factors (rain, snow, wind) heater use is largely discretionary. Heater use can be reduced by preheating, the use of heated steering wheel/seats [and very few LEAFs don't have those, just 2011 models and not even all of them], and just dressing appropriately for winter.

I owe you some updates so here they are:

Lost my first capacity bar 2-1-14. Stats on that day were:
--Date of Manufacture 8/11
--Date of Service 6/26/12
--Date of P3227 update 7/2/13
--Geographic location - McKinney, TX 75071 (Dallas)
--Average miles/kwh for the life of your Leaf 4.6/kWh
--Current odometer reading 9761
--Current AH capacity reading from LeafDD or Leaf Battery App 53.92
--Exact date you took current odometer reading and current AH capacity 2-1-14
--Days per week parked in the sun (fractional days OK) The first 8 months it was parked out in the sun all day, every day; 0 since I purchased the car

We moved from Texas to Pennsylvania on March 27, 2014, so that's going to put a bit of a monkey wrench into your data. Degradation has slowed drastically since that time. Here's more recent stats:

--Date of Manufacture 8/11
--Date of Service 6/26/12
--Date of P3227 update 7/2/13
--Geographic location - Lords Valley, PA 18428 (Scranton is the closest "large" town)
--Average miles/kwh for the life of your Leaf 4.1/kWh
--Current odometer reading 15206
--Current AH capacity reading from LeafDD or Leaf Battery App 53.35
--Exact date you took current odometer reading and current AH capacity 11-24-2014
--Days per week parked in the sun (fractional days OK) The first 8 months it was parked out in the sun all day, every day; 0 since I purchased the car

I just got Leaf Spy and thought I'd supply my data on my 2013 with about 24 months of regular commuting round trip 45 miles. I'm a big fan of your work with the degradation model.

Manufactured – 5/13
Delivered - 9/27/13
P3227 update (I don’t know but it has had all its shots from the dealer)
Location – Seattle, WA
Miles/kwh – 4.8 (from dash)
Odometer - 30234
Capacity – 58.396
Date - 9/10/15
Parked in sun - 1 days/week
Note it is parked outside in Seattle during the day in partial sun during the work week. I figure that is about 1 day in the sun per week.

Is there any way of determining if and when my 2013 had the P3227 update?

Or would I have to ask the dealer?

I thought the P3227 was for 2011-2012? Someone tell me if I'm wrong please.
