This seemed to take a bit longer, but we are driving less than before. Seems like miles is a larger impact than time. Fortunately, my drive to work is just 8 miles. I never had a regular commute with the car when we were living in Sacramento. I now drive the same route almost every day to and from work. Every day I start the car and have low 60's as a guess for range. I get home every evening and the car is at about mid twenties for remaining range. So a surface street easy drive 16 miles round trip uses 35 to 40 miles of guesstimate. It also reduces from 12 bars to 4-5 bars of capacity (usually 5). It is enough that I can't make the trip twice without charging. But as a work commuter that I own, it works just fine for now. But it will be replaced with a standard range Model 3 once they start producing them. I'm in no hurry, and I have been invited to configure if I wanted the long range pack, but I'll keep waiting.

Apologies for the off-topic...

How do you get a scale on both sides of the graph ? I've wanted that for a long time.

Also, I'm not able to open the interactive link.
Regarding the scale on both sides: In the Chart editor, under the CUSTOMIZE tab and "Chart & axis titles", the Type pulldown has an option of "Right vertical axis title" - that's where to put the title text. The axis itself is in the "Right vertical axis" pulldown under the CUSTOMIZE tab. (Note: I developed the chart using the old Chart Editor, so I have no direct experience with the above. YMMV :? )

Regarding the link: Try this one (not sure why the original went bad, hoping this one will keep working):

1st Bar: 4/6/2015 - 24,496 miles - 54.01 Ah
2nd Bar: 6/11/2016 - 33,691 miles - 51.24 Ah
3rd Bar: 8/25/2017 - 46,100 miles - 47.47 Ah

1st-2nd Bar: 431 days/bar - 9,195 miles/bar - 2.77 Ah/bar = 155 days/Ah = 3319 miles/Ah
2nd-3rd Bar: 440 days/bar - 12,409 miles/bar - 3.77 Ah/bar = 116 days/Ah = 3291 miles/Ah
We haven't dropped our ninth bar, yet, but I thought I would take a look at what has happened over the last eight months. Here is the latest reading:

Date: May 3, 2018
ODO: 54,629 miles
AHr: 46.02 Ah
SOH: 70.15%
Hx: 48.18%

1st-2nd Bar: 431 days/bar - 9,195 miles/bar - 2.77 Ah/bar = 155 days/Ah = 3319 miles/Ah
2nd-3rd Bar: 440 days/bar - 12,409 miles/bar - 3.77 Ah/bar = 116 days/Ah = 3291 miles/Ah
3rd Bar-Now: ?? days/bar - ?? miles/bar - ?? Ah/bar = 171 days/Ah = 5882 miles/Ah

Of course it is normal to lose less capacity over the winter than over the summer. As such, I expect these numbers to turn completely around now that it has gotten hot. We'll see how things look when that next bar drops.

With the current battery conditions and now that the weather has gotten warm, my wife returns home from her 49-mile commute with about 35% SOC in the battery. Come next winter, she will have more days when she takes the hybrid rather than the LEAF to make her commute -- maybe 30 or more.

Lost 3rd battery bar today

Hello,
Well the day finally came. 6 years, 5 months, 21 days and 70111 miles.
Lost the 3rd Batt Bar today (currently 9 bars).

I'll add the Batt stats to this post tomorrow after it has fully charged. :?

Very nice.

I'm at six years, 96k miles. I lost the 4th bar long ago, and I'm probably going to drop #5 in the next few months.

Just a few weeks from six years and surprised to still have 10 capacity bars. Only 37,500 miles but it has been quite hot here in San Jose this July.

Please don't start new threads for individual capacity bars losses. Can you imagine if everyone here on MNL started a new thread for each capacity bar they lose?

Prior to the 30 kWh software update, we'd already has over 17 4 bar losers on the 30 kWh cars: http://www.mynissanleaf.com/viewtopic.p ... 68#p525968.

Hopefully the mods merge this into http://www.mynissanleaf.com/viewtopic.php?f=30&t=8802.

Like RegGuheert I feel like I'm closing in on that 4th bar. I have a feeling it will be December of this year.

Past stats, pulled from my signature in case I change it in the future:

Purchased Certified Pre-Owned February 2015, 36,033 miles
First Bar lost: 39,879 miles, July 2015.
Second: 50,225 & 8/16.
Third: 62,960, 11/17.

Latest stats:
Date: August 2, 2018
ODO: 69,411 miles
AHr: 45.28 Ah
SOH: 69.02%
Hx: 60.86%

Sporting Milestar MS932 tires with ~ 20,000 miles of wear (used as summer tires since purchase) and averaging ~ 4.8 miles/kWh in the summer, 5.0 in Spring and Fall. Closer to 3.7 in winter tires Oct-March.

The car is racking up fewer miles now that my husband has his own EV, so that 4th bar miiiiiiiiiight stretch to March. The battery is losing SOH a little faster than the Battery Aging Model for Boston, but then again I'm 40 minutes in from the coast and there's no shade at my office. My car is baking on the blacktop and today is 93F with a heat index of 101F. The car was manufactured 6 years 8 months ago and the Battery Aging Model estimates 70% SOH at 7.8 years.

An amazing battery aging report by the "early adopters". When was this last updated? I may have missed it, but the statement about "recent" and "2013" indicates that not too much information on the "Lizard" has been included?

Also, LeafSpy Pro monitors remaining energy in both kWhs and GIDs - are the comments on GIDs still applicable when determining range? I've assumed (guess what that means) that GIDs are the more accurate representation.

The latest battery report on my replacement "Lizard" battery. It does seem the range is taking a nosedive recently - I'm going to have to watch closely.
