I'd be thrilled if we got more Sunshine, I'd take that over more battery life ! :mrgreen:

I have data for every month, but to keep this from becoming too unwieldy, I'll only include sample data points for 2015:
12/28/14 / 93mi / 9 L1/L2s & 1 QC:
96.4% SOC / 289 GIDs / 22.4 kWh / 63.28 AHr / 100% SOH / 97.45% Hx
04/27/15 * 2,927mi * 95 L1/L2s & 1 QC * 4.5 mi/kWh (for the past month):
97.3% SOC / 287 GIDs / 22.2 kWh / 61.02 AHr / 98% SOH / 94.22% Hx
06/29/15 * 4,264mi * 132 L1/L2s & 2 QC * 4.4 mi/kWh (for the past month):
97.2% SOC * 292 GIDs * 22.6 kWh * 62.99 AHr * 100% SOH * 97.09% Hx
Funny that these are essentially the best numbers I've ever recorded--right in the middle of the hot, central valley, California summer!
07/31/2015 * 4,695 mi * 138 L1/L2s & 5 QC * 4.4 mi/kWh (for the past month):
96.6% SOC * 286 GIDs * 22.2 kWh * 61.26 AHr * 98% SOH * 94.61% Hx
During October 2015, I decided to use the CHAdeMO Quick Charger at my local Nissan dealer on a regular basis, as sort of an experiment, and my battery has--perhaps coincidently--really gone to hell during this time:
10/01/2015 * 6,281 mi * 187 L1/L2s & 7 QC * 4.4 mi/kWh (for the past month):
97.3% SOC * 280 GIDs * 21.7 kWh * 57.73 AHr * 95% SOH * 91.41% Hx
10/31/2015 * 7,281 mi * 211 L1/L2s & 16 QC * 4.5 mi/kWh (for the past month):
96.2% SOC * 268 GIDs * 20.8 kWh * 57.69 AHr * 92% SOH * 88.37% Hx
(Note that these are the worst/lowest values I have recorded since buying the car about 10 months ago. I am NOT going to use the QC on a regular basis again!)
12/01/2015 * 8,007 mi * 239 L1/L2s & 17 QC * 4.0 mi/kWh (for the past month):
97.2% SOC * 268 GIDs * 20.8 kWh * 56.98 AHr * 91% SOH * 86.89% Hx
01/31/2016 * 9,308 mi * 289 L1/L2s & 18 QC * 3.8 mi/kWh (for the past month):
97.3% SOC * 266 GIDs * 20.6 kWh * 56.59 AHr * 91% SOH * 86.09% Hx
I've fallen behind on collecting this data, but here's my latest:
10/28/2016 * 16,525 mi * 495 L1/L2s & 28 QC * ~4 1/2 mi/kWh (for the past month):
96.4% SOC * 258 GIDs * 20.0 kWh * 55.49 AHr * 89% SOH * 83.82% Hx
Relative to what others are reporting, I am not very happy with the falling Hx and SOH values on my 2015 lizard battery. It doesn't matter to me much right now, but I suspect I'll be even more unhappy in another 2-3 years.

There must be something positive about frequent cycling. I put on over 100 highway miles on my last trip, with only one QC, and my number bounced up a little. If I had a driving pattern similar to o00scorpion00o would I get similar results? My climate is similar. But I just don't need to drive that much.

Seems to show high health for 59 AH, ?
My health is now back to 99% but I guarantee because it will be sitting for the weekend it will all drop a bit again.
battery AH and health can be 6 %, lower from not driving much and higher from driving and charging a lot particularly at higher charger power.
I wouldn't have thought the climate in Central Massachusetts would be similar to an Irish climate at all ? perhaps for a small part of the year , here we don't get extremes.

Today I ran leaf spy again and low and behold, 100% health and 65.4 ah. I forgot to upload the screen shot to Photobucket on my android. I will do it tomorrow.
January 2015 Leaf with about 33,500 miles.

A US Gallon of Petrol as we call it is 5.00 USD, reasonable by our standards, down form about 8-9 USD a few years ago when oil was about 100 + USD a barrel.
Our Government screws us with tax about 70% of petrol costs is tax. We're screwed here with tax in general.
Electricity costs 18 US cent per Kwh day rate and about 7.4 US cent per Kwh night rate.
I have free work charging so that pays half my commute, if I get a 60 Kwh EV next, which I am hoping will be in 2018, then work charging will meet 100% of my commute.
So as you can image driving EV saves me a lot, I work shift so don't benefit 100% from night rate but even so compared to petrol or diesel it costs a hell of a lot less , EV sales in Ireland are pathetic though, range is a huge issue despite living on a small Island. :mrgreen:
What are fuel costs there and electricity ?

Fuel and its taxes varies by state, here it's currently ~$2.10/gal. Electricity can vary widely by location. What I buy off the grid averages about $0.15/kWh, but our solar makes most of ours.
Temps here are more extreme than Ireland, it's true, but we don't get as hot as the American southwest, and heat is the big degrader. So, your fairly constant temperature probably contributes to your results?

Our temperature probably does contribute to increased battery life, however as I point out regularly, if you do not drive a lot or charge at a higher current rate , then your reported leaf spy data will show less battery health and capacity. I do not know why. But I know this because when I am off shift and not use the car much the reported stats drop. When I use it a lot they increase and the week I work 72 hrs of shifts it shows the most capacity. I got a 2 hr total commute per day on top of that.
My battery temp bars rarely get to 6 and only if I fast charge in warmer weather, but those that DC charge a lot seem to get 6 and more a lot in warmer weather, so it will be interesting to see their leaf spy data, but it's probably different , a warmer battery from fast charging than a battery that bakes all day in the sun.
A 2014 leaf I ran leaf spy on last year after 40,000 miles had 99% capacity and way more DC charges than I have.

$2.29 per gallon US and $.125/ kWh average. My electric company dissuades time of use metering for some stupid reason. I commute 80 miles round trip per day after working 11 hours. My streamlined CBR250R was getting 110 mpgUS this summer since it was hot and dry. 17,000 miles per year on the bike and 9,000 in the Honda Fit when there is snow. When my son needs a car soon I will look for a Leaf even though gas is cheap here. Upstate New York has the cleanest grid in the USA.

Wow, 2.29 per gallon, hardly an incentive to go EV ? then again Americans usually drive much larger CC cars than us poor Europeans where 0.8 L to 1.6L is all too common. Then again we drive diesels a lot too where 60-69 MPG U.S is quiet common but yes, diesel is filthy and the E.U base tax on Co2 and not Nox and PM.
We pay here in Ireland, on top of the electricity Kwh cost , Co2 and PSO tax, PSO being public Services Obligation levy.
On a windy day Wind energy can provide up to 55% of our total electricity requirements.

As promised, here's a Leafspy Shot of my Leaf from yesterday.
Leafspy shot on the leaf pretty soon after getting it in January 2015.
This is after a year and 18,000 miles, I have did not see 67 AH in a long time.

Hear is another Leaf spy shot, so as you can see it varies quiet a bit, this is about the lowest I've seen it, probably when I wasn't using it much.

This is a shot of another Leaf I took a while back at a DC charger, it was a 2014 so about 2 years old at the time, note the amount of DC charges. This is what I'm saying, Leafs charged and used a lot report higher stats, particularly when charged at higher currents.

Use it or lose it?
Maybe it's optimized for the coming autonomous uber/taxi fleets.

No, I don't think it's ever lost, otherwise leaf spy would never show my AH and health going back up.
I really have no idea why through high usage it shows better results.
Showing lower numbers doesn't mean anything as far as I can see.

Sitting around does seem to always make EV batteries more sluggish on capacity. Quick charging will wake them up again even though in the end it is probably shortening cycle life.

Excessive quick charging maybe but the 2014+ leaf battery seems to be vastly more robust than the original.
I would certainly not be worried about daily quick charging , even 10 mins can give a decent amount of range and even better for the battery.
The current Gen 24 Kwh doesn't heat a lot on the quick charger and this climate probably helps a lot with that also but even when it's reasonably warm a single fast charge will hardly take it above 5 temp bars only rarely have I seen 6 temp bars.
What's interesting about my leaf is that I really do trash it and have to charge more as a result, this will no doubt eventually have an effect on battery life long term but I am quiet happy with the results so far.
The 30 Kwh does seem to heat a good bit more on the quick charger as a few people here have reported, good or bad ? anyone's guess. I'm still waiting for leaf spy data for the 30 Kwh here.

Have a 2015 SV. Build date 7/14. Supposedly a lizard as per dealer. Currently have 13,000 miles. No QC. All L2 charging.
Did a Leaf Spy check on 6/25 with the result below:
GID 287
102.1%
SOC 97.2%
Just this morning I checked again after what should have been a 100% charge and got the following:
GID 255
90.7%
SOC 97.4%
I know with the difference in ambient temps, being 4 months apart, the GID may be lower, but how much of this 10% drop in 24 months is due to the degradation itself?
