To add to the data pool, I took my Gid-meter this past week to three other Leafs after completing a '100%' charge and got the following:

1. 7.5 mos, 8600 mi., 269 Gids (95.7%), 5x charges/wk from 60% to 100% overnight, Orange Cty.
2. 7 mos, 7500 mi., 269 (95.7%), 4-5x charges/week from ~25% to 100% thru mid-day, San Bern Cty (inland So Cal).
3. 10.5 mos, 10000 mi., 265 (94.3%), 4-5x charges/week from ~40% to 100% thru mid-day, San Bern Cty (inland So Cal).

My charging pattern is closer to #2. Considering my higher mileage, I'm not feeling too bad about my recent 260-265's. But, if a later dip into the 250's doesn't correspond to a rise in the day's temp, .... ;)

Thank you, Richard! JP, any additional details you could share? These folks are not on MNL, correct? Would you remember the color of each vehicle? Did they mention turtle mode? Is it fair to assume that these cars spend the majority of the time in San Bernardino Valley? I hope you don't mind me asking, but if we could get the last five digits of their VIN and CarWings nickname for tracking, that would be good.

Having this data in a thread is marginally useful.. How about a spreadsheet.

As I said, he doesn't live in Phoenix or he would have a bigger loss. I believe it just gets accelerated here. He's an outlier with that many miles, not the norm.
And there aren't "several" with 20% losses, maybe one. Please don't exaggerate to help make your point. I know of six with 15% losses because they just lost a bar. The seventh one may have a 20% loss. If so, they will lose another bar soon and then we'll know. Also, your battery %s are incorrect. Right out of the manual, other than number 11, three of the bars are 7% and the rest are 6%. These are the true figures rounded to the nearest per cent.

Just to make it official, I lost my 12th bar tonight. 1 year and 6 days into ownership, with only 9550 miles. I heard this great quote recently that seems appropriate: Will tears short out my laptop?

Good idea. Can you post the link to the actual spreadsheet (above takes me to the form). Also maybe add Average driving efficiency...

Oh no. That is discouraging. Sorry to hear that. I'm sure I'm not far behind.

I think we have enough data points at this juncture to declare this a real problem... The big question is, will this continue at this rate or is it an initial issue that will taper off... The answer to that speaks volumes about the real magnitude of the issue.

Phx AZ Leaf, 16000 miles...Life time 6M/KWH.. Loss one bar this week,2 days after getting a perfect score on the one year battery check ...I thought maybe the software upgrade had something to do with it,but the dealer said no..

One year charging routine..
First 6 months were all 100% charges,I was attempting on every 60 mile work trips to break previous M/kwh records ..I think I did well but Leaffan did better :)
The following 6 months I charged 60% of the time to 80% ,those were day trips and 40% were 100% charges where I drove at night..

I think i may do 95% of my charges to 80% doing the hot summer and 5% when I need the extra miles..
Doing the winter Im going to do 80%/100% charges and 20%/80% charges..

Im really not seeing a big difference between my 100% charges and the other AZ cars that were doing 80% charges,that could change tho as the cars get older..

If i were Nissan for 2013 ..The Leaf / Eco mode with option to go to (Drive). 80% charges with the option to go to 100% charges..

leafkabob sorry about bad news and I believe what shrink said he is not that far behind. shrink I did not expect big loss for you because your car experienced only half or the summer heat (delivered in Aug). Here in OK 90+ already with bad part that is not going much down at night, therefore I am trying to figure out what will be the best to protect my battery. What I done put car in storage mode with 5 bars and using my Ninja. Of course last is not going to work for my main 65 commute because I am carpooling. Question to both of you how you did you try to protect car from sun during day and where was during day and night, What was most battery temp and if that was during drive or charging?
