Another month has rolled by and I just cleared 36000 miles this afternoon. I've lost a few more GID's. As of Nov 1, I have 262 GID's at full charge. SOH=72.27% Hx=62.68% Odo=35889 mi. 62 QC, 670 L1/L2s. I lost 6 GID's last month compared to 5 GID's during the same time last year. I'm down two bars and if the numbers from Nissan are right I'll lose the third bar (70%)in December and the fourth bar (63%) around April at about 45000 miles. At that point I'll be down to 66 miles total range with a 55 mile commute. Also my No Charge to Charge expires on Dec 14, 2017 so I'll have to pay for charging a crappy battery nearly every day at a public station just to be able to get home safely.

Leaf SV 30 kWh purchased 12/10/15, Delivered 12/16/15
Leaf spy results 1/28/16 (took forever to find an ELM that worked)

Ar=74.5
SOH=93%
Hx=89.12
Odo=13 (at delivery), 547 (current), first trip of 103 miles (with two charge bars remaining, used over a week) 1/20/16
3 QC (the dealer must have done the first two), 13 L1/L2 (one charging event for 5 minutes to test new 240 outlet, all others prior to 1/28/16 were overnight L1).

Couldn't get a picture of the battery balancing bars on screen 1 for some reason, but I they look really out of whack (to me) so cells may be unbalanced.

I have been at 70% SOH for almost a month and only down 2 bars. One person reported dropping 3rd at 67% so we may have a way to go. 2 people reported dropping 4th at 59%.
 
Dec 1 and I'm down 4 more GID's. 258 GID's at full charge AH = 56.58, SOH = 71.13% Hx = 61.81%. 37029 miles. Battery degradation seems to slow down over the winter. If I have to get down to 60% to get a new battery, that's around 218 GID's. Even with 258 GID's i'm down to a 70 mile max range. At 218 GID's my range will be about 60 miles max with a 55 mile commute. Either I drive another car or plan on getting a quick charge every day. Nissan had better step to the plate here. The car goes in to the dealer in a couple of weeks for the annual battery check. I suspect that they'll claim it's normal and that the battery is fine. My best guess is that the battery drops the fourth bar in July or August at about 45000 miles.

Good morning. What year is your car and what part of the world do you live.

Thanks

You can look up Jamul, CA on Google Maps. I found http://www.mynissanleaf.com/viewtopic.php?f=44&t=20924&p=456139#p456139 stating he has a '16.

BTW, your sig consistently has the wrong units for battery capacity "30KW". Battery capacity is measured in kWh, not "KW". See http://www.mynissanleaf.com/viewtopic.php?p=509385#p509385.

Thankyou for pointing that out. I just fixed it.

Seeing as how the topic is 2016 30KWH battery data, it never occured to me to add the model year and with 37000 miles on the car it seems obvious that it's not a '17 :lol:

Hi John. I have a 2016 as well. It was made in April of 2016 though. I don’t know if that makes a difference.

We haven’t noticed any degradation yet but we have a 1/4 of the mileage and we live in an environment that is a cooler than yousr most of the time. Summers can hit 40 (around 100 f) though and we do fast charge once per week. The hottest I have seen the batt is 7 bars. Hopefully we won’t have the problems you have had. It is our bridge car to get us 4 or 5 years to retirement and then we’ll switch to either a long range Leaf or maybe a model 3 Tesla.

Thanks for sharing your info and best of luck with getting things resolved.

John.
 
It now appears that either there is no difference in battery longevity between early build (2015) 2016 cars and 2017 cars, or the difference is modest. They are ALL more like the 2011-3/2013 pack than the 2015 Lizard pack, or even the pre-Lizard "Wolf pack."* This suggests that the problem with with the chemistry, and that it hasn't been changed. Let's hope it was changed (for the better!) in the 2018 packs.



* I've given the rest of you plenty of time to come up with a better name for the improved 4/2013 through 2014 packs, and you've left it to me. So I'm going with "Wolf pack" because wolves are strong and tough but don't do well in high heat, and because it's a terrible pun.
 
I expect to replace the battery by next summer. Until then, I'll have to limp along and recharge in town as necessary. I like the car in general but the battery problem is a deal breaker for me. In retrospect, I should have leased instead of purchasing outright. Even if Nissan replaces the battery twice under warranty, it won't remove the bad taste from my mouth. The 2018 leaves me flat. I expect that battery to have the same issues with heat as the current 30 KWH battery. Maybe the 2019 with a 60 KWH battery will have a TMS and active cooling. If not, then Nissan is out of the running for my next car. There are going to be a lot of competitors in the electric car field in the next few years and Nissan is destroying their reputation by not proactively addressing this problem.

I've got 3 years left to pay on this car. By then, off-lease Model 3's will be available. If I do have to replace the battery twice under warranty, I'll probably sue Nissan under California's "Lemon Law". That's assuming some bright young lawyer hasn't bought a class action suit by then.
 
Down to 72% SOH as of today compared to my last check in at 79% in September. Still haven't lost my second bar though. What a joke. Already starting to get tight on my 66 mile commute, especially as temps drop.

The biggest issue is the chemistry - it can't even tolerate moderately warm temperatures. Tesla's chemistry as used on the Model S/X (and hopefully 3), on the other hand can run 30-40C all day while only losing a nominal amount of capacity. In fact, Tesla uses waste heat from the motor, inverter and onboard charger to warm the pack to 30C if available. Turn on range-mode - it'll warm the pack to 40C. The pack has to hit 50C for the car to start actively cooling off the pack.

You run a LEAF pack at those temps constantly and you'll end up getting a new battery under warranty no problem - TMS or not.

Now you know why I picked 75º as my alert point to change charging habits on my LEAF...

Where are the Tesla data to confirm this, I.e. when TMS becomes active for the 18650?

I used to think my degradation was due to sitting on the hot TX dealer lot all summer, but now I am starting to think it is just time. Mine was built the same month as yours and I am at 67% SOH.

Agree, this doesn't seem to be purely a temperature issue. Certainly, those in warmer climates appear to be most effected.

We do have hot summers here, but the car has rarely, if ever, been charged under high temperature conditions. It is garaged most of the day and all night, and charged in the garage or other shaded environments, usually at night or the early morning. It also never sat at a full charge in triple digit temperature.

If I were the main driver, perhaps the car would be more babied. But more coddling should not be required of mainstream drivers.
 
Let's face reality, the 30kwh pack is a steaming pile. If we lose the fourth bar soon we could theoretically be on track for five pack replacements under the warranty.

I've also been reading up on the Florida lemon law, it has to be an uncorrected problem within the first two years, but it isn't clear to me what happens if the problem recurs on such a long cycle. Probably no help there but will be looking into it further.

If they offered to swap it out for a Sentra we'd take it in a heartbeat.
