On all of the vehicles I have data for (the replacement battery for the 2011, the 2015, and the 2019), Hx started out above 100% so it must be referenced to some nominal value and not the actual starting value for the particular battery.

1. So you now agree that Hx is a percent.
2. Most data indicate that it's only Leaf 2 which has Hx above 100%. Where're the references indicating Leaf 1 had Hx greater than 100%?

GerryAZ said:
I have the most data for the 2015 and Hx did seem to inversely track the change in internal resistance over the 4-1/2 years I drove that car. I observed/tracked internal resistance by noting voltage drop under full load and calculating approximate internal resistance periodically.

But here you note that Hx inversely tracks the "change in internal resistance", which contradicts your previously statement that Hx is a percent,
i.e. Hx indicates the relative value, in a percentage, of the battery conductance over time.
 
Since I apparently confused you, I edited my previous post to clarify that percentage reduction in Hx somewhat tracks with the increase of internal resistance over time. Also, I was wrong--the 2011 replacement battery (original chemistry from Japan) did start at 100.00% for Hx and 100% for SOH with initial readings taken across the street from the dealer (although the terms were not defined the same in the older versions of Leaf Spy so Hx was called Hlth back in 2013). SOH was still 100% after the 12-mile drive home from the dealer, but Hx dropped to 88.08%. The Leaf Spy readings at home with the odometer indicating 29,382 (29,370 when battery was installed) were: AHr=65.60, SOH=100%, Hx=88.08%, QC=30, and L1/L2=859. The morning before the crash on January 4, 2015, the Leaf Spy readings were: AHr=53.94, SOH=82%, Hx=66.27%, QC=57, L1/L2=1408 with the odometer indicating 50,416 miles. The 2015 started with the following Leaf Spy readings on February 7, 2015 (across the street from the dealer): AHr=64.38, SOH=100%, Hx=101.25%, V=391.37, Odometer=9, QC=1, L1/L2=4, and SOC=85.7%. The last readings I have for the 2015 were on August 10, 2019: AHr=39.84, SOH=63.44%, Hx=34.14%, V=388.32, Odometer=82,434, QC=340, L1/L2=1483, and SOC=80.9%. As noted in other threads, the 2019 started with AHr=175.15, SOH=99.29% and Hx=98.19%. Hx initially increased then slowly decreased as the car was driven and is presently at 102.12%. Unfortunately, I don't have any experience with the 30 kWh or 40 kWh batteries.

Thanks for clarifying your views, and it appears we both agree, i.e. Hx is a percentage representing the battery's relative conductance (mhos)
over time as the battery degrades for Leaf 1.
 
Well hello everyone...I confess I can't read all 187 pages devoted to this topic! It is as varied as a discussion on religion or politics!
I recently bought a 2017 Leaf SV from Colorado (cooler temps?) and I live in Alberta, Canada. This winter my battery temperature gauge often showed only 1 bar. It gets wicked cold here. I do leave it plugged in overnite (L1). Summer and I see 3 or maybe 4 temperature bars, that's all.

At 27,000 miles I just lost my first bar, horrors! I don't have Leaf Spy and I have no idea what it is, how much it costs, or if I really even need it. My gas SUV has a fuel gauge, I didn't go out and buy another fuel gauge for it.

I have petitioned my Nissan dealer to update my BMS per TSB PC630 (also known as NTB18-039) with hopes it will properly format my 'gas' gauge capacity reader and I might gain back my lost 12th BC bar. Will update you on that. Not many Leaf's (Leaves) here in the land of V8 hemis.

If any of you have had this TSB done on your 30 kWh battery Leaf, I'd love to hear the results of it please. Thank you!
 
My 2017 S was at 92% SOH after 6 months and then went to 97% or so after the BMS reset which occurred at about 1 year. After 3 years, I'm at 93% SOH and 22k miles now.

1st bar goes at about 85% SOH. Colorado can get hot and how the car is charged makes a big difference. 85% SOH is possible but you really won't know until the BMS update is done.

... and a few months pass to allow for recalibration
 
I guess I need to start a new list for 30 kWh 4 bar losers since old list at https://www.mynissanleaf.com/viewtopic.php?p=525968#p525968 arguably isn't really valid now due to the firmware update to fix capacity reporting (https://insideevs.com/news/338528/update-nissan-has-software-fix-for-2016-17-leaf-30-kwh-battery-reporting-issues/ https://static.nhtsa.gov/odi/tsbs/2018/MC-10143139-9999.pdf aka campaign PC630).

Here are links to the 30 kWh 4 bar losers I'm aware of post update.

Please chime if I'm missing any 30 kWh 4+ bar losers, made mistakes, double-counted someone, etc. I've included their initials or MNL user name to help avoid confusion or duplication. I'm probably missing some since I haven't been closely watching this and other 30 kWh threads.

1) AB, Dallas, TX, Sept 2020: https://www.facebook.com/groups/nissan.leaf.owners.group/permalink/4389071457830328 - he says he got the update in July 2018 already.

3) GaleHawkins, Feb 2020: https://www.mynissanleaf.com/viewtopic.php?p=580411#p580411 - date might not be correct

Unclear about johnlocke's case due to the date https://www.mynissanleaf.com/viewtopic.php?f=30&t=23606&p=529513&hilit=replace#p529513, the campaign date and whether the replacement was premature.

my sister's 2016 30kwh leaf SV hit 4 bars in Feb 17, went to the dealership to start the process and didn't get the replacement (40kwh pack) until middle of march.

my own 2016 leaf S just hit 2 bars 2 months ago, so I'll probably lose the 4th bar within 2 years. :(
 
My 2016 Leaf SV dropped from 9 to 8 bars last week. I plan to talk to dealership this week and will provide update on the outcome. 71k miles. I use Leaf Spy Pro.

Thanks for your post and look forward to your dealership visit update. Your battery held up well compared to our 2016 Leaf SL that lost the 4th bar November 2019 5 weeks after we bought it. Mileage was 24,000 when the 4th bar was lost. Our car had just come off lease and I have no history other than it had lived in the St Louis MISSOURI area.

Your car already had the BMS update, right?
Yes, vehicle had BMS update in August 2018 prior to my purchase. Plus, I had annual EV Battery Usage Report done at dealership November 2019 where they also applied the "recall - P9312 - leaf battery plate NTB19055"

Detail:
I have record from previous owner for work done at Nissan dealership on 08/30/18 that has this entry:

Mileage 61641

PERFORM RECALL
PC630 LEAF 30KW BATTERY NTB18-039
OPEN RECALL
REPROGRAMMED LIBC
 
Then you should be good to go for a new, probably 40kwh battery - unless you get unlucky and a 30kwh battery is in stock somewhere in your region. Even then, many of the 30kwh packs are very good.
 
Has anyone had a second battery replacement from Nissan on the 2016 Leaf? My 2016 dropped it’s forth battery bar last week. This is on a replacement battery that was installed in 2018. I’m in Phoenix so the heat is killing the batteries, currently at 69,500 miles. The dealership ordered a replacement battery. I am hoping to get the larger 40 kWh in a week or two.

You should get a 40 per release from Nissan back in Jan 2020. We took our 2016 SV in 30 Dec 2019 and got the car back 12 Feb 2020. We bought the off lease Leaf 15 Oct 2019 showing 9 bars with the Nissan dealership stating we would be getting a new battery pack soon. It was showing 21,600 miles. It failed 5 weeks later at 24,000 miles. For our car this was the first replacement. 8 months/10K miles later State Of Health (SOH) is down by 4%.

Maybe a 40 kWh will last longer for you. I have started recharging in the 50%-75% SOC range to keep down the max temp of the pack but now the air temps are getting into the 70-50 F range daily. We getting about 150 mile range per charge at 40-60 MPH and 120 miles at 70 MPH and have some over 35K miles on the car now. If I am not going to be driving it my daughter takes it to college, etc.

Dealership checked out battery and confirmed battery due for replacement under warranty. Dealership has no ETA on when Nissan sends out my replacement battery.

That is good news your claim has been validated. I was told by the shop service writer it was the division office feet dragging that dragged out getting a new battery ordered in my case but a call to the National Rep got things back on tract fast. Keep us posted. Maybe you will get fast service. The Nissan dealership had never replaced a battery before mine.

After losing the fourth bar, what kind of tests does the dealership on the battery to check if it is eligible to be replaced or not? Thanks.

Here are snippets of text messages I received from dealership:

we performed the battery usage report, you are eligible for a battery replacement.

The dealership first checked it out and said it looks like it's eligible. Perhaps they ran the Annual EV Battery Usage report. BTW I had that run in November 2019.

Then dealership said they needed to have a "certified Leaf technician" look at it to confirm.

Then later the same day:
Good news! After our diagnostic, we did not find anything else wrong with the vehicle that caused the battery to fail. We sent in our findings with Nissan and the battery has been approved to be replaced under warranty.

I assume the second snippet is result from certified Leaf technician.
