I realize the dealer has little incentive to care (barring decreased sales of future Leafs when the problem gets around by word-of-mouth), but Nissan has a huge incentive not to be known for crappy battery life! Why don't they have someone in the corporate office who calls the dealers repeatedly and explains this and then reminds them regularly? This would seem like a pretty cheap fix (or, rather, workaround) for at least part of their battery life problem.
May be easy way is for Nissan to enable a setting not to charge the battery above 70% before delivery, rather than training sales staff. During delivery they can flip the switch to enable owner to chage to 100%. Yes charge to any % option need to be there too.
Bourgee how is your battery doing since it looks like it went through a Texas summer on the dealers lot?
I am probably one of those unluky ones. I am already at 98% SOH, 93.5% HX, 78Ahr Capacity at 700miles. I think my battery is not going to do well. At delivery my battery was at 38 miles. I am assuming Dealer had my battery baked at 100% charge in TX summer :-(

I would say yours was healthy when you got it. Mine was at 68.93Ahr 86% SOH about 2 weeks after delivery. It went up to 72Ahr 90% after a month of full cycles and has been going down since then. 57.62AHr 72% as of today.
I tried to get them to take it back after I got LeafSpy but the dealer blamed Nissan and Nissan blamed the dealer.

Then do not participate in that part of the discussion, and certainly do not provide wrong data. You have @DaveinOly running off on a tangent now that LeafSpy is unreliable and maybe the LEAF battery is not so bio-degradable as trolls like me assert. So where are we with your battery ? Well, about 20% degradation after ~ 4 years. Right on track to have a hobbled battery after the warranty expires. Nissan thanks you for your business, and looks forward to selling you another 7 year wonder-car.

I agree with the remainder of your post, and am happy to read your example of a shallower degradation rate these last two years. Gerry in AZ reported the same degradation slope from new to 7 (or was it less ?) bars.
SageBrush,

I feel I must correct the misinformation you are reporting about my cars. My 2015 is almost 32 months old with 47,699 miles and still has 11 capacity bars. The 2011 was still at 11 bars on the replacement battery at 50,422 miles and 42 months after the original battery was replaced at 8 bars (28 months and about 30,000 miles). Therefore, I lost a total of 5 bars on the 2011 and 1 bar so far on the 2015 in a little over 98,000 total miles. It is disappointing to hear of 4 bars lost on several 30 kWh batteries with very low mileage.

If I'm wrong, I appreciate the correction.
My memory was of your 2011 model, and my post referred to your Ahr loss per distance. Not fast or slow, but constant. Correct me if wrong.

2016 Leaf SV acquired in Dec 2015.
Currently at 32,600 miles.

It lost its 1st capacity bar this morning. GOM has dropped to 95 miles with 100% charge.

Charging habits:
100% charge daily overnight on level 2..
1 hour level 2 top up to 80% at workplace on most days..
Occasional use of DCFC to 80% about once a month for some weekend long drives...
About 30 DCFC sessions in 19 months.

Battery charging pattern is not extreme by any measure...

Thanks for the data! By the way, by "east bay", are you referring to the Oakland/Hayward/Fremont part of northern CA?

Yeah, he could be east of the hills, e.g. Antioch/Concord/San Ramon/Livermore, which is an entirely different (much hotter) set of microclimates.

LeafSpy data? Build date/delivery dates?

Ahhh... Dublin gets quite hot during the summer and sometimes and is frequently within 5 to 10 degrees of the hottest cities in the Bay Area during the summer.

San Mateo's much milder.
