Charged to 100% every time with no degradation of any kind after three plus years. Heat and letting it sit are the issues.

Yes- Highest temp 103. It never sat at 100%

How do you mange to never let your car sit at 100%? I'm just curious, seems like it would be a lot of work and take an awful lot of planning to pull this off every day.

Yes, people with unusual circumstances can't be used to justify screwing most people over as Nissan has done.

Yes, some planning is required, but it's not that difficult. As an example, the previous evening I know in advance whether the next day's
travel exceeds my Leaf's range, e.g. availability of QCs and travel time necessity, in which case the ICEV is used. Then the Leaf doesn't get
charged the previous night. I rarely if ever return home from that day's business with more than 30-40% SOC. If returning with the ICEV
and local business travel is required and time permits, I'll charge the Leaf at home for a few hours at 220V, but only to the SOC which results
in enough range to return home at much less than 100% SOC.

You set a charge end timer for a specific time and the car calculates back from there. You drive the car shortly after that charge cycle is done. I’m not sure how that is difficult or requires much planning of any kind. I guess you have to plan to remember to plug it in.

Right. It doesn't require much planning at all, provided you have a known steady schedule.

I'm guessing you have a 2011-2015 leaf, because the charge timer on the 2016 is screwed up!! It overestimates how much time it needs to finish charging (including balancing).

I've had to set my timer to end at 10:30am, even though I will use the car at 8am (ends just at 95+% SOC). But that only works when the SOC starts around 40+%. If I get home with 20% SOC, then I have to adjust it down an additional 10 minutes, because of that damn code that overestimates how long it really needs. My 2013 also had some variability, but it was well under an hour.

So with Nissan's current battery chemistry and charge timer, you can forget about relying on that to preserve your battery.

Well I have a 2016 SV and the charge timer sucks, not accurate at all. Plus I actually have a life, I go do things I don't just go to work and go home, was a total pain trying to adjust and plan for when I will be going out next and trying to make sure it wouldn't be sitting at 100% SoC.

Not only that even after doing this for a few months I noticed my battery was degrading anyway, despite all this silly monkeying around with charge timers every day!

I no longer care I just charge it and drive it. My lease is up in about a year anyway so unless the 2019 Leaf has a hilltop reserve or some way to set what SoC you want I will move on to something different. The bottom line is the end user shouldn't have to jump through hoops because Nissan doesn't know what they're doing. How hard would it have been for them to implement a hilltop reserve mode or just do it like Tesla does (user selectable SoC)?

They all do that. I ignore the car's time estimate and go by the charge rate per hour. In my case that's between 5% and 6% on L-1. When I get my 20A L-2 installed it will be about 20% per hour, or about 11% per hour for the 2018 Leaf, which I will also have to manually unplug because Nissan is run by idiots.
