This is pretty much how I do it. It keeps things simple and easy.

Good idea. I will adopt this as my new strategy. Saves having to change timers to charge to 10% and then change them back afterwards.

I lost my first capacity bar this morning. I had only charged to 80% and read 186 gids and 9 SOC bars. My last 100% charge was 228 gids 3 days ago. Will charge to 100% tomorrow to see if it reads lower then that.

That was expected. 186 gids is just 80.5% of the 231 gids I get on a 80% charge, and not the 85% we thought when the first capacity bar should disappear.

Yes, as expected for Tick Tock.

You seem to be confusing some numbers, however. 85% is the threshold of current capacity to maximum design capacity before you lose that first bar, and that means the threshold is 231 Gid on a 100% charge. It has nothing to do with 80% charges, which would meet the 85% capacity threshold at 185 Gid.

I guess I'm the 5th(?) guy in AZ now who officially lost a capacity bar (happened today).

I almost always charge to 80% only, and maybe once a month I charge to 100%. When I charge to 100%, it's only because I need 100% and usually I charge from 80% to 100% just before I leave, so I don't let it sit at 100% for very long. I always plug the Leaf in as soon as I get home to top off to 80%. But if it's during Peak hours (1-8pm summer, 9-5 am/pm in winter), the Blink is off during peak so the Leaf doesn't get topped off until Off Peak hours kick in.

I charged to 100% this morning for a trip, and noticed 12 charged bars on the left, but only 11 capacity bars on the right. Is that normal or is it kinda odd that there's more charged bars on the left than the capacity bars on the right?

Anyway, I've had the car for almost a year now (about 2-3 weeks shy of a year), and I'm at around 16.5K miles. I always garage the Leaf. Only used the DC QC at Riverview Toyota a couple of times a few months ago when it went online. Most of the times it's L2 charging from a Blink in my garage.

Last summer the highest battery temperature I saw was 7 bars.

I also notice that lately, my 80% charge completion only shows 9 bars instead of 10 bars. This phenomenon started happening maybe 6-9 months ago once in a blue moon. But it's now happening almost on every 80% charge. In the past, if I restarted charging just for kick to see what happens after 80% completion, the 10th bar will show up under a minute or so. Now the 10th bar wouldn't show up until 5-6 minutes later. Note sure if that really means anything anyway.

I have not taken my Leaf back to the dealer for the 1 year battery checkup yet. I'm planning to do so in early June.

Yes, normal for a 15% reduced capacity battery. You have 100% of the available 85% capacity of the battery.

It is hard to see how those who have lost a capacity bar could have "about 80% capacity remaining after 5 years". That would be about 1% loss per year. In Arizona? Doesn't seem likely. This is the first report of someone who has been pretty careful with the battery (as far as the info reported shows), yet still lost one bar in less than one year. I think a bit more guidance from Nissan about expected rate of capacity loss would be helpful.

Yes the only common theme left now is that they are all from Arizona. Charging patterns appear to be less of a factor in these cases than maybe we thought. Last year saw crazy temps in August. http://www.eastvalleytribune.com/arizona/article_e9bcef0a-d5b6-11e0-a61a-001cc4c002e0.html

I imagine a high of 117 and an average for the month of 109 was enough to cook a cell or three.
