Here we are for mine:
??? GIDs 66.91 AH, SOH=84.19%, Hx=62.24%, 57781kms (35903 mi.) 22 DCFC and 1721 l2

Very very similar to yours now.

June update. 304 GID's 67.18 AH, SOH=84.52%, Hx=62.11%, 79144 total mi. 34215 mi on new battery. 21 DCFC and 665 l2 charges on the new battery. Battery is averaging .7%/mo loss over 23 months. Significantly better than the original battery but still I'll be lucky to get 75000 mi. out of it. That would be driving it down to a 4 bar loss and a sixty mi range. On the other hand, I'm down to driving less than 600 mi/mo with the Covid thing. Still expecting to get something else after I hit 100K. The Model Y is in the lead now but I'd like to have more choices. GM and Ford look to be out of the running (neither has actually started production) and the VW bunch is having big-time software problems and they can't seem to get away from DieselGate which still could cost them billions. I like the ID 4 a lot and the cost with Federal and state incentives could bring the cost down to under $30K which would make it competitive against a Tesla Model 3. I'd also like to see a single motor Y with the larger battery @ $44K or thereabouts. The Koreans could surprise me as well. The Cybertruck is an outside shot but I don't see it showing up until late 2021 or 2022 and I'd have to convince myself that I would want to drive a full size truck all the time. I've done that before and parking is such a pain plus climbing in and out. Maybe if the air suspension automatically lowers itself in park?
Thanks for the updates!

At the current rate of degradation, how long do you think you have before you'll be forced into a new vehicle? 3 years? 5 years? Sounds like either situation should still net you plenty of options. I have a cybertruck reservation myself, but it will replace my model 3. Am apprehensive about driving a full-size truck, but the 500 mile range is just way too tempting as a family road trip vehicle!
I'm expecting to get another 20K-30K mi before I trade it in for something else, so figure 1-2 years. I expect to be down to about 75% at 100K and it gets harder to get a full day's use without a charge up in town. At $70K I can't afford a dual motor with the 500 mi range just to tow a horse trailer 3-4 times a year. $50K for the 300 mi version might work if the ride is nice enough and I get room for 3 adults and 2 large dogs. The size is an issue though and it would have to replace both my Leaf and the 15 year old Tundra. I live on a farm and need a truck for hauling supplies and lumber.

Just started intermittently losing the first bar at 85.4%. Last time this went on for a couple of months before losing it permanently.
Hi John, you gave SOH=84.52% in your last update, so did you mean to write that you were losing your first bar at 84.5%?

Sorry to hear it, but as you know better than most it is inevitable. Just for info my first bar went at just under 85% but was never intermittent, I wonder if that is a mod in the firmware update that I have.

I'll post my figures later in the day.
Take care.
Sorry about that. Fumble fingers. I have corrected the entry.

July update. 306 GID's 66.81 AH, SOH=84.06%, Hx=61.36%, 79803 total mi. 34874 mi on new battery. 21 DCFC and 685 l2 charges on the new battery. Lower loss rate is likely because I'm driving a lot less. The first bar has permanently disappeared. It did flicker on and off for several days but it finally disappeared for good. As long as the Covid thing is going on, I'm going to be driving a lot less so the car will last a bit longer then I originally expected but I expect that 100,000 mi. is about the limit of what I can tolerate. I'll be down to 70-75% of the original range and at that point, it becomes difficult to do my usual commute without charging in town somewhere. If don't have to make that commute anymore, then the car will be good up to maybe 120,000 mi. but will be down to 8 bars by then. I had originally hoped that the battery would last 160,000 mi. before needing to be replaced but now I'm on the second battery and it won't make it past 120K. At least the second battery might be good for 70-75K. Too bad I didn't get the 40KWH upgrade.

Hi John and all,

I'm going to post results that are completely the opposite of those above...

July update. 309 GID's 67.58AH, SOH=85.03%, Hx=63.71%, 59951km (37251 miles).

So that is a significant improvement in every aspect of battery health, that I cannot understand or explain.

I have been using the car just as before, except to add in a holiday trip this weekend just gone where each way was about 200 miles and involved two quick charges. On the way I had the battery temp gauge right to the top (not the red bars) as I drove at 80mph for basically the full charge, in-between two fast charges.

So it was pretty intense, and I would have thought quite bad for the battery, quite the opposite to the way I generally try and nanny the thing. But it seemed to really enjoy it!

If the battery stays like this for a few weeks I could get my 12th bar back, 4 months after losing it. Now that doesn't really mean anything, but I never thought it would happen by hammering the car!

I look forward to the car gaining 200miles of range and autonomous driving next month if I treat it badly enough!

Regards.

I've gone back and reread your posts. If I were you, I'd run the battery down to 40% and charge it back up to 80% rather then a couple of small charges every day. Also charge it up to 100% once a month and run it down to about 20% to exercise the battery and BMS. Fast charging sometimes seems to help re-calibrate the BMS as well. I have Solar PV here at the house so charging at home is always preferable but sometimes I need a bit extra to get home safely. 10 minutes at a fast charger or a half hour at an l2 charger usually enough.

Thanks for that John. It really is a baffling task trying to look after these things. On the one hand we know that lithium chemistry is most stable away from its extremities of charge. So small charges in the middle must be best for the cells. However the BMS apparently isn't capable of correctly assessing the available capacity when treated like this for a prolonged duration, leading to reduced accuracy of SOH and SOC etc.

In this way it appears one can't win. I will try, a little to stick to the battery middle ground, but I will be mostly just using the damn thing.

Contrary to most reports pre purchase, it is neither quiet nor comfortable, but it does work. So I shall just get on and use it, with no particular inclination to prolong its life forever, as I would much prefer to go through with my Cybertruck reservation. (Although it is possibly completely ridiculous to compare a 7000euro car to what will be a nearly 70,000euro truck!)

Regards,
Tom.

Re: 2016 30 kWh Battery data

So I made an appointment and took my 2016 (manuf date 5/16) LEAF to the Nissan dealer, along with the instructions for PC630 battery management system upgrade. My car has 12k miles and LeafSpy reads SOH 87.2%. The response from the LEAF trained technician was that my car was not eligible for the service!?

Looking at the Service Campaign Bulletin (https://static.nhtsa.gov/odi/tsbs/2018/ ... 9-9999.pdf), it says " all 2016 and 2017 model year LEAFs equipped with the 30 kWh battery globally are affected."

Does anyone have any insight into this? Are there cars in the group that aren't affected? Or do I just need to argue with my dealer or try another dealer.

I realize it won't affect the function of the car, but it might affect value when I go to sell it in a year or two.

Thanks

The only way I can see your car not being eligible would be if it has already had the service.

Yes, but I checked the codes on Leaf Spy and as best I can tell, it has not been updated.

I'll have to keep working on this.
