In what way is the pack tweaked?

MY 2013 leaf has oddly gained a little bit of life back over the last 3 months as well. Its slowly and steadily gained back 5 GIDS since March. While I hope the trend lasts...guessing it has to do with the warming weather and deeper discharge cycles we have been giving it since winter.

Wow, that's darn good for a year old AZ LEAF. What was your mi/kWh and how much was left when you got to 100 miles?

Lol, about 5 miles/5.2m/kW h.

Certainly your new LEAF has also "kept losing capacity after losing the first CB" as well. But your *indicated* capacity rose 3.6% from 54.9Ah to 56.9Ah, which is more than I recall any 2011/2012 LEAF indication rising. While that is still (barely) within the 4% error window Nissan claims for the new firmware, it is darned close. At least it appears that the reading when you lost the CB was pessimistic.

If you have a meter which gives you the "Hlth" parameter shown on LeafSpy, would you mind sharing that with us?

For reference, our 2011 (manufactured three years ago this month) with ~19,000 miles currently shows 58.85Ah and Hlth of 78.36%. We just had P3227 done a couple of weeks ago and both values are still dropping, but Hlth is already *significantly* lower than it had been before the update while capacity is still a bit higher. Previously they were 58.04Ah and Hlth of 85.66%.

Back on topic: I recently drove 85.4 miles at 5.6 mi/kWh, arriving at my destination with 16.1% SOC remaining. (This was just after the P3227 update and capacity indicated was ~61Ah at the time of the trip.)

I am starting to believe that the 2013 does stretch the lower 20% of the range (likely to reduce number of needed tows). When driving to the teens this week (because I forgot to charge overnight), In a mix of 55 mph and some stop and go traffic, I made my 13 mile commute in 9%, which is 2% less then I have ever gotten starting from a high SOC. I don't have a beginning and ending GID reading, and know that my driving was not some how that much more efficient then previous trips, especially since 5 or so miles was at freeway speed.

Separately, while I have been excited to see my gids roll back up from 254 to 259 this summer, I realize it just from the warm battery.

I managed to get about 100 miles yesterday. 2015 SV. Real world conditions here around Boston. Some was back roads, some was highway, some with lots of traffic, so I got a boost from the braking. I get about 1 mile per %(the battery percent, not the GOM) but I never tested how close it was. As I was driving home, my Waze app was telling me I had 37 miles to go, and I had 39% battery left. They tracked each other(when waze went down a mile, so did my battery %) When you get to 10 miles on the GOM, it turns to ---, when you get to 5% on the battery meter, it turns to --. So I don't know my exact % when I got home, but round trip I drove 102 miles. If the math holds right, I could have gone 103-105. Not sure on the manufacture date, but it was delivered to the dealer in April 2015, and I bought it Aug 29th.

I haven't run a full-->zero discharge for distance yet, but my new 1025 Leaf, from purchase to now(about 200 miles, mainly commute and local), shows average 5.1 mile/kwh.
This should give me 5.1x24=122 miles distance.

You don't have access to the full 24kWh.

more like 5.1x22 = 112 maybe a bit less. Not sure how much the 2015 holds in reserve.

Only had my 2015S a week, but so far, showing avg 4.6-4.7mi/kWh, and GOM seems to consistently equal %SOC. So that comes pretty close to the 21 usable kWh I believe folks were seeing on prior model years.

I've got a very low traffic, very flat, roughly 5mi loop around my home. I believe I've read that the battery performance actually improves the first few weeks of use. And with current weather, I've never seen other than 5 temp bars. When would be the ideal time to attempt a 200 mile charge?

I've also got a rather long, steep (by MN standards) hill nearby where one could attempt some sort of regen efficiency test. Is it accurate to say that if you regen from 50 to 5 (and then brake to zero with no regen bubbles showing) that you will be going 35 or 40 again by the time you burn what you recaptured?
