My Leaf was purchased in March this year(2013) and was most probably build in 2012. In early july I checked my battery capacity for the first time with Turbo3's Battery App.
The capacity was 101%, with the 100% set at 67AH.
This reading was almost the same, every time I checked, it varied between 99% and 101,40%, so after a few weeks I stopped checking every 2/3 days, assured, that my battery was OK.
At the end of August this year, the dealer did the P3227 update. This went smooth and did not affect any of the readings which I had from the Battery App.
In the middle of September this year, when driving a bit more "firmly", more powerfull, there was some strange behaviour from the regenerative braking. The regenerative braking, just fell off, and the normal brakes took over, lots of times, in situations where it never happend before, in similar conditions, like simply linear slowing down, with 10-20KW regen.
Don't get me wrong, I know the regen falls off in lots of situations, but this was different.
The next day, I noticed the temperature gauge still was at 5 bars, which usually never is the case after 1 night letting the car alone at the usual night temperature at the time of year. (10-15 degrees Celcius(50-60F))
Didn't use the car for 2 days and the temperature gauge was still at 5 bars.
The temperature bar has definatly changed.
Other strange fact about the regen since that day is that often the 4th regen "bubble" only becomes active when the 5th capacity bar is gone. This was usually after about 2 bars.
Last week I used the Battery App to check capacity again and with horror noticed a 91% capacity reading!
Since I didn't check every day, I can't say if the capacity dropped in 1 day or in about 3 weeks, just noticed that it dropped 10% within the month. And yes, in that month the P3227 update was done. There was no different capacity reading directly after the update.
There were no extreem temperatures that month, the car was not quick charged that month.
The capacity loss is real and also noticable as I cannot drive the same "distance per bar" as usual.
Latest Leafspy Pro gives the same results. I check it every day now, and it stays at 91.xx% (last digits change a bit, sometimes up, sometimes down, like always btw)
I 'm going to ask my dealer about this capacity loss, but have already a feeling how they are going to react, like "that 101% was a wrong reading and the P3227 update corrected that".
In that case, it could be stated that I had 10% capacity loss in the first 6 months and within 7000KM(4350mi). Is this acceptable? What would be the best way to approach my dealer?
If I wait and it drops another 10% somewhere in the next 6 months, then I surely don't have to argue/debate if its warranty or not.
Could it be caused by this 1 bad cellpair, wich I noticed earlier?

My expectations about battery loss are 1-3% a year as my year-distance will be 12000-1500KM(7000-9000mi) and we have a relative cool climate. (the Netherlands)
Thanks in advance for any suggestions / advice.
