Yes, that is my plan. Ironically, I took it into the dealer on Friday and had the battery report done. He said "the battery looks good...in fact it is excellent!". It was on my way home from the dealer that I noticed the 12th bar was missing. :oops:

Ouch! Do you plug in and let it charge as soon as you get home? If you do and you want to delay the replacement, you can set your charge timer to delay start and complete charging an hour or so before you leave in the a.m.

To be clear, the battery report doesn't rate the battery, it rates how well the driver is treating the battery. Just read the text next to the stars, they are all about driver behavior. The only thing the battery report shows about the battery is the capacity bars, the same thing you can read directly from the dash. You could have a Leaf that has lost half of its original capacity and still gets a battery report with 5 stars on all the items.

Service techs who are new to the Leaf don't understand this. I've had to explain it to a number of techs who have proudly shown me that report and told me how well my battery is doing.

We have one in the family tracking similarly, maybe a little worse. Will be interesting to see what Nissan does with these, by my accounting that could be three or four pack replacements under warranty.
I wonder if a manufacturer can change the original terms of a factory warranty when they resell a vehicle when they were the lessor.

I charge at home 5-6 days a week, no QC, but I do charge to 100 percent.

By the look of the curve, I'll be losing number 4 shortly after 20000 miles. Will let you know...right now I have almost 19000 miles.

One odd thing is my range is still 90 miles, and when new I was getting 105 miles, so barely a 15 percent drop. I would expect more like 20-25% loss of range.

Here are the Leaf Pro numbers as of 18366 miles.
AHr 53.5
SOH 67%
395.42 V
Hx 64.86
SOC 97.8%
244 GIDS

I have a 3 year lease, so It's up in Dec 2018.
Hope this helps.

Strange. 90 miles range when I am at 57Ah and I am lucky to get 65 before low battery warning. What is your avg mi/kWh?

More like poor nomenclature


the "battery test" is in reality an evaluation of "you" and your charging habits. nothing more. has nothing to do with the actual battery as you now well know.

Nonsense.
The battery checks (at the owner expense, naturally) are part of the car warranty. Nissan does not warrant the human.

"Excellent" just means that Nissan is not on the hook for a replacement battery.

The bottom line is they handed me a report and talked about how excellent things are, but failed to mention the part of the report that clearly shows 11 bars.

Not a great start to our relationship.

Re: 2016-2017 model year 30 kWh bar losers and capacity losses

New owner of a 2017 S Leaf up here in Chicago area. Little concerned at a recent drop off in Ahr and SOH. I know it is really early but it seems to have happened really recently which makes me nervous about what is to come. Wondering if I am a victim of the dreaded "sat on the dealer lot all summer at 100%" phenomenon. It certainly isn't Phoenix hot but I am not sure at what point is too hot to sit at 100%.

Build date is 3/17. Purchased new 9/12/17 with 30 mi on odometer.

First leaf spy on 9/17
9/17/17 375 odo Ahr 80.513 SOH 100% Hx 96.15 2QC (done by dealer) 13L1/L2
9/21/17 745 odo Ahr 81.340 SOH 100% Hx 97.26 2QC 21 L1/L2
9/26/17 1205 odo Ahr 81.960 SOH 100% Hx 97.97 2QC 36 L1/L2
10/06/17 2132 odo Ahr 79.353 SOH 99% Hx 95.02 3QC 58 L1/L2
10/13/17 2684 odo Ahr 78.113 SOH 98% Hx 93.41 3QC 71 L1/L2
10/17/18 3026 odo Ahr 77.644 SOH 97% Hx 92.71 3QC 78 L1/L2

It all seemed to start to fall after the quick charge I did between 9/26 and 10/6. It was just a hook up to make sure I could access the network in case I need to use them in a emergency in the future. Charged from 44% to 80% in 15 min and then stopped the charging.

Charging Habits:
Common charging practices are L1 charging overnight most nights. I have L2 charging at work so I will usually charge a couple of hours during the day right before heading home from work. Usually at least once a week arrive at work with 20-40% charge and then charge to 100% on the L2. I time it so that it is done charging close to the time I leave for the day. Charged to 100% several times with the L1 at home. usually on the weekend since it will have more time to sit on the charger. I try to keep it between 20-95% as much as I can. If I remember correctly the battery temp got to around 93F during the quick charge and I think that is the hottest I have seen so far.

I will update since I know I am really early just a little concerned that the SOH and Ahr are starting to drop fairly dramatically in the first few thousand miles.

Don't get too upset at drops under 5% or so. There is normal variation, and the first year is supposedly when the biggest declines in SOH occur.
