Apr update. 309 GID's 67.61 AH, SOH=85.06%, Hx=62.97%, 77856 total mi. 32927 mi on new battery. 20 DCFC and 635 l2 charges on the new battery. Battery took a big hit last month despite not driving much for the last couple of weeks. It still looks like it will last longer than the 100,000 mile warranty limit but it won't be very capable. I still I'm looking forward to Tesla's battery day announcements. The ID3 is mired in software problems so the ID4 is looking iffy at this point although VW claims that it will ship in 2021. GM is still talking big but most of what they're selling at this point is sizzle rather than steak. It seems more likely that I'll see the Cybertruck before either GM or Ford get their trucks out. The Model 3 or a Y looks like the best bet right now.
This is the norm. My 30 kwh pack (which was NOT updated to new SW) also had stats drop during low/no driving periods but they rebounded when the driving picked back up.

I know a LOT of people will say the higher numbers are meaningless but I traveled mostly freeway 114 miles in January on a single charge which is about the best I could expect "at any time of the year" 3 days before she was killed.

Mar update. 314 GID's 68.73 AH, SOH=86.47%, Hx=65.70%, 76636 total mi. 31707 mi on new battery. 20 DCFC and 610 l2 charges on the new battery. The battery is continuing to slowly degrade. Even in a cool wet Feb, I still lost 2 more GID's. I'm down about 13.5% from new. 21 months in, the old battery was down to 262 GID's, so the new battery is doing much better. The difference is notable and I expect to hit the 100K warranty limit well before the new battery would qualify for replacement. I'm still still expecting to be down about 25% at 100K. I expect that as the weather warms up deterioration will accelerate again. I'm looking forward to Tesla's battery day announcements. The ID3 is mired in software problems so the ID4 is looking iffy at this point although VW claims that it will ship in 2021. GM is talking big but most of what they're selling at this point is sizzle rather than steak.

On another note, is anyone still interested in my experience with battery deterioration? Should I continue to do these updates or let the thread die?
Yes please keep it up!

The 30kwh packs will be around for some number of years still before they are out of defect/capacity coverage.
I think it's still a great option for those that can't afford anything else and this data provides some expectations.

Hello John,

I just thought I'd post a reply to say, yes please keep going, because I've recently purchased a used Leaf 30 in France. I had the bms update done at purchase because the car was down at 66% SOC (my thanks go to the Leafspy team for allowing me to see more info than the garage could). That was two months ago, now after the update and 900 miles I seem to have pretty similar battery state to you so it might be interesting to compare evolution (although I'm not driving much at the mo).

The day I collected it 28 Feb 2020:
??? GIDs 67.72Ah SOH=85.20% Hx=64.03% 54,405kms (33,805miles) 19 DCFC and 1625 L1/L2

Today:
303 GIDs 66.35Ah SOH=83.48% Hx=61.11% 55,850kms (34,703miles) 19 DCFC and 1674 L1/L2

First registered 31 Dec 2015 so I have until the end of 2023 (about another 1335days), if the warranty and Nissan are solid!

I consider the loss of 1.7% SOH in 50 days of gentle temperatures and gentle driving to be pretty outrageous, I expected that kind of loss per year! I charge a little bit at my workshop slowly (from my solar install) whenever I'm there, so SOC usually isn't near 100 nor near LBW. If this is how the battery behaves in ideal conditions, well, yikes.

If it continues at this rate then I would expect to be at 66% SOH by September of 2021. I'll start looking for the Nissan warranty contact details...

Keep it up,
Regards,
Tom.

May update. 310 GID's 67.92 AH, SOH=85.45%, Hx=62.97%, 78576 total mi. 33647 mi on new battery. 21 DCFC and 651 l2 charges on the new battery. Battery actually improved slightly. That's the first time I've seen that happen. It still looks like it will last longer than the 100,000 mile warranty limit but it won't be very capable. I'm looking forward to Tesla's battery day announcements. Sounds as though Elon has some big news. The ID3 is scheduled to debut for sale in June and there are rumors that the ID4 will show up by fall although VW still claims that it will ship in 2021. GM is not going to build any new EV this year and Ford is still at the preliminary stage for the F150 and Mustang EV's. It still seems more likely that I'll see the Cybertruck before either GM or Ford get their trucks out. It appears that a single motor Model 3 or Model Y with the long range battery could be available soon. That would fit my needs quite nicely and be a little cheaper as well. The ID4 remains on the list but would need to come in under $40K before I'd consider it. I keep looking at the Cybertruck as a possible replacement for both the Leaf and my 2005 Tundra but I'm not sure about driving something that large full time.

Expect to get a new battery around 50000-60000 miles assuming Nissan is still in business. I expect that Nissan will have to replace most of those 30KWH batteries under warranty. If you are lucky, Nissan will upgrade you to the 40KWH battery like they do in the US now. It is a nice car except for the battery. I will say that 1674 L2 charges in 34000 miles is excessive and likely why the battery is down so far. Sounds like the original owner charged it every night whether it needed it or not and probably to 100% to boot.

May must be the favourite month for Leaf batteries because I also got a an increase in health/capacity...

304 GIDs 66.52Ah SOH=83.70% Hx=61.48% 56,686kms (35,223miles) 19 DCFC and 1699 L1/L2

I agree the previous owner must have charged to full every night after having tootled five kms to work and back. Not great for the longevity, but a very forgivable beahviour for someone who bought a car and not a hobby. Nissan's battery management should be better designed to cope with this naivety.

But then again, I am racking up the charges without racking up the miles, because I (prior to lockdown) drive 7 miles to my workshop plug it in, then drive home for lunch, then back to the workshop for the afternoon, on charge again, then home again. So that's two charges (assuming the timer function isn't on meaning I have to override, triggering another charge count) for 28 miles!! And as far as I understand things this should be good for the battery - always keeping it around the 60% mark. But its actually during this lockdown that my wife has been using it (she's a nurse), doing more longer journeys (20 miles each way) and more longer overnight charges that it has supposedly picked up capacity, go figure.

Fingers crossed for increased capacity next month too, I mean why not... my friend with his Model3performance said that now that the weather has warmed up his car is even more stupidly quick!

June update. 307 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?

Note: July 2. I just corrected an error in my reporting. It should have said 307 GID's instead of 304 GID's. I've corrected the entry above.

Just started intermittently losing the first bar at 84.5%. Last time this went on for a couple of months before losing it permanently.

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!

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.
