My dealer sent me a nice email about a week ago asking me about my 6 month check up. It was actually pretty well crafted, and I give them credit. It said I must be enjoying life without using gasoline, and having to deal with oil changes. Though it was time for my Leaf's 6 month check up. On this list they had tire rotation, CV joint inspection, and a ton of other stuff that I know it does not need. I am going to take it to one of the local tire places up the street, or take it on base and do it myself. I won't be taking mine in till the 1yr battery check next March. So some dealers do send out fliers for this sort of thing.

Apparently, the average of 76% is based on average Phoenix LEAF-driver milage of 7,500 miles per year. If 76% is an 'average' based on 7500 'average' annual milage, if you are driving over 7500 miles per year, you will end up with lower than 76% after 5 years in warm climates. [Correction: Phoenix, no estimates posted for other affected areas]

[UPDATE: After this article was published, Nissan used the actual mileage of the seven cars in the test to provide additional data. "The average mileage for the cars investigated was 19,600 miles, and the average in-service time was 14.7 months," wrote the company's Katherine Zachary. "Average annual mileage [of those cars] is about 16,000 per year, more than double the average Phoenix customer mileage of 7,500 miles per year."]

Also, I don't remember much about my stats classes, but mean is relatively meaningless without distribution, median, min, and max. Is averaging these numbers meaningful with a sample size of 7? Of the 4 cars I know about the spread is 12,000 to 24,000 annual milage.

So the only way to have 76% capacity retention in Arizona is to drive just 7,500 miles a year??? That doesn't sound like a very useful car to me. The cars Nissan tested were not "high mileage", the average wasn't that much higher than their assumed 12,500 miles. I would characterize the Arizona 7,500 miles a year average as "low mileage", being far below the national average. Still sounds like spin to me.

I think the 7,500 annual miles used in testing were based on markets other than the US. More to the point:

7,500 x 1.6 = 12,000 km

To me, this looks like a figure that would perhaps apply in Europe, and some other parts of the world. I looked at WRS statistics, and cars seem to travel less than 10,000 km per year in Japan.Image

Quote from the article: " average Phoenix customer mileage of 7,500 miles per year." Maybe it's yet another completely false report?

Anyone know why Phoenix Leafs would see less than national average annual vehicle miles? Are they perhaps counting rentals, fleet vehicles or Leafs on dealer lots in this statistic?

Yfhong's information has been added to the 1 Bar Lost table as well. Thanks for the catch on that one! :)

I saw my first 9 bar 80% charge on June 25th.
I haven't had a battery temp. below six bars since mid April.
I only saw 7 temp. bars this summer a few times. I can park in the shade of a tree at work, but have to move it as the sun moves.
Charges outside in my carport.
Charge to 100% maybe twice a month, the rest of the time charge to 80%. I did try to baby my battery this summer by keeping the max SOC to 7 bars.
5 stars on my yearly battery check.
Life time average of 5.0 mile/kWh
Added to the wiki, thanks so much for the full set of information the first time around. Really appreciate that! :D
