My advice is to not go OCD on it. Sure, give it a little love but don't go extreme. Enjoy it as a normal car and drive it.

leafdriving said:Hi everyone. I lost my first bar yesterday. Kinda bummed out since I didn’t expect it to happen so soon.
Here’s what I get from LeafSpy Lite:
AHr= 54.98 SOH= 84% SOC= 70.9% Hx= 81.09% 384.78V -0.45A odo= 23,798 3 QCs & 1417 L1/L2s
The build date is 10/13 and I bought it used in February of this year. I don’t drive much; I’ve only put 2900 miles on it since I bought it and I have to admit I baby the car. The car’s original owner lived in Cupertino, CA and I’m in east bay (SF bay area). I don’t know much else about the previous owner’s habits other than location and what LeafSpy provided me today. I also assume he always charged it to 100% since the “Long-life mode” was turned off when I got it.
Here are my habits: 80% mode on, usually keep the batter around 50%, occasionally get down to 15-20% remaining and then L1 charge it at the latest the next day, and never QC it.
We did have a pretty hot summer this year (hit over 110 a couple times) and I wasn’t able park the car in the shade. The highest I ever saw the battery temp was 7 bars and that was about 3 times.
I've read a lot of posts of folks who are in hot climates losing their first bar at much higher miles. Based on the info I’ve provided can any one shed some light on why I’ve probably lost my first bar already? I’m surprised given the build date, miles, almost no QCs, and the climate the car has spent it’s entire life. Part of me feels “it is what it is” but I can’t help but think that the battery is going to quickly degrade and I’ll hit under 9 bars soon after the warranty expires in 12/2018.
Thanks guys!

Fourth bar finally dropped on the way home after running some errands. Plugged it in to charge and then took a reading. Appointment to start warranty replacement scheduled for 17 October 2017.
The vehicle was manufactured in January 2013, spent it first two years in Georgia, was auctioned after lease return and brought to Las Vegas. I got it in March 2015. It dropped the first bar in October 2015, the second bar in June 2016, the third bar in November 2016, and the fourth bar in October 2017.

ahr of 36? That seems lower than the norm? or not?

How often do you recharge ? By your data it looks improbably frequent.
By the way, I graphed your data. No obvious rhyme or reason to when you lost capacity
Charges up to 80 or 100% every day ?baustin said:I have it set to charge every day, but it is on a timer, so it counts once when plugged in and once again when the charging timer activates (even if the battery doesn't need charged).SageBrush said:How often do you recharge ? By your data it looks improbably frequent.
The vehicle was made in January 2013, so the cells inside the battery are the 2012 chemistry. The change in environment, bringing it to Las Vegas, accelerated the degradation. There appears to be a distance component to the bar dropping algorithm in the Leaf. I drove it a lot during the first two years, and not as much this year, which seems to have delayed the drop. I expected it to happen months ago, and it may have, if I had been driving it more.

Thanks for the charge counter tip. That probably explains why I sometimes see unusually high counts in other posts.
baustin said:I took mine in today to get the warranty replacement started. Initially, they told me it would take about two hours. When I got there, all they said they needed was to plug in the Consult Tool and get a battery status printout of only 8 bars showing. They're supposed to call tomorrow, after it's ordered, to tell me when the replacement battery will arrive.
silverone said:I was surprised I didn't see much discussion about these swings or the effect of cold ambient temperature, because they'd be critical in evaluating a used car for someone in a cold climate. Battery temperatures didn't swing as wildly or seem to have as much of an effect.
I have Leaf Spy running on a spare phone almost all the time and logging to Dropbox. Although these are my max/min readings over a timeframe, none are really outliers from the surrounding data. It seems to take about 3 days for readings to stabilize after a big ambient temperature swing.
I've also seen GIDs at 100% charge swing accordingly from 259 to 284 over the same timeframe, although they seem to max out at 284 for any AHr reading above the high 65 range.
Based on the way the data is trending for my car, I may have a low enough AHr reading by mid summer to lose a bar after showing 103+ Hx at times in the winter! Perhaps if things continue I'll make and publish a trend of the data.
