I am probably going to jinx myself, but I have full 12 bars at 30K miles. Purchased the car on Nov 16 2013.
2013 Leaf bar loss.

you are not exceptional by any means. I have 29,442 miles on Car I got Dec 23, 2013. I am an estimated 34,000 miles away from losing my first bar

hows it going? guessing you still got 12 bars. pretty sure since you only charge to about 97.3% that a 15% loss would be around 82ish... what was your build date and date of service?

I just looked at your signature and interestingly we are at almost the same capacity:

Yep, that's mine...3/13 manufacture date...lost two bars at only 24K miles.
My lease expires April 2016. Will post if I loose a third bar by that time.

I think this is the topic in which I noted that there seems to be a real increase in pack resistance to degradation that starts with April 2013 manufacture dates. I wonder: did Nissan have some first Gen Japanese packs left over, and they were used for the first three months in Smyrna...?

Lost 1st bar on my 2013 (bought on Dec. 2013) Nissan Leaf @14717 mile, 26 months. I have another Leaf which bought on Apr 2014 which has more miles and more charging / thermal exposure, but still has all 12 bars. Since both are bought close to each other and not in the summer, I think the battery should degrade similarly. Looking back in LeafSpyPro reading history, I wonder if my 2013 Nissan has defective battery when I bought it.
One thing I noticed is that Dec 2013 Nissan leaf starts with low GID / Ahr number when it was new. I live in Irvine, CA which is closer to the ocean, so we don't see MANY hot days as in Texas/AZ. There is a discussion on MyNissanLeaf forum from another California orange county user about whether the low GID/Ahr number is a concern or not. He thought it is not since the range is similar to other higher GID/Ahr number, but now I am thinking it might indicate a bad battery which might degrade faster in time. Anyone has similar experience?

Disclaimer: My Dec 2013 Nissan Leaf is always in the garage during the night. I have foils on the inside of the garage door (product bought from Amazon just for Leaf) to reduce the heat inside. When outside temp is reaching 85F, I will drive the other gasoline car and leave the leaf in the garage with a fan blowing. I only commute about 10 miles each way, mainly surface street speed even on high way due to traffic. Rarely drive in the 65-75mh range. Also charge only every 2-3 days or so. Other Apr 2014 leaf is for my wife, and she parked her car outside always either at home or at work, and is driven daily no matter what is the outside temp with similar driving pattern except her commute is about 20 miles per day. Her car has normal GID/Ahr reading when new, and has not lost the first bar yet. If the Ahr reading is reliable, then does it mean my car lost almost 10% when I bought it new?
Note: I remember the Apr 2014 Leaf has about ~280 when new, but forgot to write it down since it was inline with what I read from internet forums.

What is that car's date of manufacture, according to the door frame sticker?

The 1st leaf is October 2013, and 2nd is February 2014. So both are within 2 month of manufacturing.

Welcome fellow 2 Leafer!
I asked that because Leafs manufactured before April of 2013 seem to have more capacity loss problems than those made later.

I checked mine again today. Door sticker shows manufactured in January 2013. Charged to 100%, Leaf Spy showed SOC at 95%.

So do I.czhp01 said:
Looking at your data, it appears that December 2013 LEAF lost 7.5 Ah in 23 months while the APR 2014 LEAF lost 8.4 Ah in 22 months. The latter car was driven almost exactly twice as far during that period. Since it is fairly well established that calendar degradation effects dominate over cycling (driving) degradation in the LEAF's battery, I would say that your numbers do not seem at all unreasonable. Note that calendar degradation proceeds linearly (or perhaps slightly faster) while cycling degradation should slow as he battery degrades.czhp01 said:
Finally, I will note that tests by 2013 LEAFs with low Ah readings found that the actual driving range of their cars when new matched that of other LEAFs with normal readings.czhp01 said:

I kind of agree that low Ah number and high AHr number have similar driving range when new. We drove on the same route with both Leafs when new and able to get over 100 miles from 100% charged to almost empty.
If the degradation is mostly calendar driven ( minus AZ / Tx high temp region), then I would think ALL cars should degrade similarly if it is not too much dependent on charging cycle and driving pattern / mileage. But this is not the case from reading other statistics. A lot of cars are still having 12 bars after 3 years. Does it mean the battery production range is wide in terms of degradation?
I saw a Tesla forum discussion and one person plotted some distribution curve on battery degradation, I wonder if someone has plotted something similarly in groups of Regions / Mileage / Calendar lapse / Years build / Charging Pattern, etc to see the correlation. I guess if the battery has wide production tolerance, it will make the comparison harder.
Too bad I was treating the Leaf as high tech gadget, and tried to take care of it as best as I can, but still lost the first bar so soon in terms of mileage -
. I am sure mine will be one dot in the below average curve.

Calendar degradation simply is degradation of the battery when just sitting there, doing nothing. It is absolutely a function of temperature. If the temperature is 10C (18F) higher, calendar degradation should be about twice as fast. So, no, you should not see ALL cars degrading similarly.czhp01 said:
The point is that most of the degradation in your two cars is calendar degradation and the smaller portion is due to driving. That is why they have similar amounts of degradation in the same amount of time even though one was driven farther.

I bought my 2013 SV in April 2013 so far with 27k and only 10 bars. Can't wait to return my lease in 2 months.
