I was really disappointed when my GIDs dropped to 281 after the first month, but now all the battery numbers are clearly creeping up.

It looks like my LEAF loves the heat! After 6 months/4,000 miles and well over 100 L1/L2 charges, the capacity (now 292 GIDS), SOH and Hx values have crept up to the highest values I've ever measured!

2015 Leaf SV got it on July 25 2014, checked it was made 05/2014 so it's over a year old now!!!! but only about 11 months on the road and over 22k miles.

I just noticed that there are 2 Ahr. My best guess is one is available and one is total? Since When I divide the high value (given on the screen with the bar graphs and number of charges) by the low value (given on the screen with SOC on top) that the value is then the SOC%.

Can others confirm if that's correct?

292/281 = <4% increase, so it would be <1kWh. Although I would love to think that Nissan is going to give me an extra kWh of capacity when they replace my degraded pack, you would think they would have taken advantage of it by advertising a 4% increase in range for the 2015's also.

I wonder if the increase was more than that, with a greater percentage held in "reserve", and the computer allowing slightly deeper charge as time goes on, to maintain the 292 (available) GID level. Even good batteries have calendar and cycle degradation, which these 2015 packs seem to be defying. A reserve buffer could explain that.

Could be. My GIDs just went back up again to 292. Can't complain. See the last reading in my signature.

Where do you guys find the super mini ELM 327 with off button and Bluetooth that will work. I keep getting ones from China that are suppose to be 1.5 ver but don't work. Tired of waiting on wrong ones that don't end up working. Any in the states? I have a 2011 with a Dec 2014 install of a lizard battery and would like keep track but can't. I also want to monitor my 10 bar car.

Not sure what you mean by "off button" as mine doesn't have one but I don't think you need one.

I bought mine on ebay from China.

Auction has since closed but the heading was

"Mini ELM327 V1.5 OBD2 II Bluetooth Diagnostic Car Auto Interface Scanner"

Here's the cheapest buy it now with an exact match from a different seller than the one I got:

Thanks, I hope it's not some of the new cheaper batch branded 1.5 but is sent as 2.1 when it is received. Was able to borrow a friends and last night got these on Leafspy lite.

This was a 12/18/2014 replacement Lizard battery into a 2011 @ 22,273 miles.

My 2011 with Lizard battery will not charge to 100%. The highest it charges is 89.7%. I guess that makes sense because it is a little larger capacity. The onboard software says it is 100% but Leafspy Lite says it is 89%. So, if we are to believe it helps your battery not to charge to 100%, it leaves 10% headroom. I don't know if this is what they are normally doing with all warrantied cars or they left out a step to include the extra 10% SOC

No, Leafspy is reporting the ACTUAL cell charge, or close to it, so you are seeing the headroom that Nissan built into the Leaf to extend the battery life, like every other EV manufacturer. Before Leafspy we just weren't able to read it. Your original battery would have read very similar, if you had Leafspy back then.

Ok, but on my second car (10 bar car) SOC is stated as 97ish% on Leafspy. So there is basically little headroom. So the (12 bar car) slightly larger capacity Lizard battery is being used with a little more (10%) headroom and will only charge to an actual 87ish%. Whereas my 10 bar car charges basically 97ish%? How is it that other owners in their stats are listing 97ish% SOC while using Leafspy?
So anyway... If I were to put a 30kwh battery in it, it would still only see 24kwh, I wouldn't see increased range because the battery would only technically be charged to roughly 70% (true), but onboard software would think 100%. If the my15 are building in headroom, then the leafspy would not show nearly 97ish% SOC, as they appear to be doing.

OK I am not at 100% but just got my OBDII and Leafspy so I couldn't resist. Leased the Leaf Dec. 20, 2014 so it is now 7 months old. Mfg date is 9/14. It's a 2015 S with QC. Before pulling these stats I drove it on the interstate, QC'd for 15 minutes, then more interstate, then another 20 minute QC. Total drive was 85 miles. So the battery temp is quite hot. How high should I let it go before being concerned?

7/25/2014 Leafspy stats:
Location - Buford, GA
AHr = 64.38
SOH = 100% (very happy about this, but can it be true?)
Hx = 101.10%
odo = 6,298 miles
24 QCs & 149 L1/L2s
Temp F = 110.9 F avg (9.5)
SOC = 84.6%
GIDs = 250

I'm a little bit confused when I hear people wondering if there is substantially more capacity in this 2015 pack on the tune of 6kWh improvement.

The high voltage cutoff seems higher than my 2012.. 97% vs 94%. 4.1-4.15V also seems a little bit higher. If you go to turtle, your pack probably is around 3V/ cell. If it is more like 3.4V/cell, then maybe there is more capacity.

My gut feeling now is that the 2015 pack actually has less capacity in favor of more heat resistant formulation, hence the HVC alteration to compensate.

No, the 2016 pack will be a 30Kwh pack instead of a 24Kwh pack. However, a 2011-2012 has to have an additional brace added to accommodate a slightly larger pack space size of a 2015 battery. My 2011 still with original battery will roughly charge to 97% while my lizard in my other 2011 will roughly charge to 87% as witnessed by Leafspy. But the cars onboard computers state 100% charged. These things lead one to believe that the 13-15 may have slightly more headroom but the 6kwh we are referring to is the stated increase for the 2016 model SV and SL rated at 30Kwh while the S will remain rated at 24Kwh.

If this is true, then someone should be able to come up with a "fix" to allow for 100% (or at least 95+%) charging in a 2011-12 Leaf. It would also suggest an 80% charge is a waste of time. The reality is we are leaving several (more than 5?) miles "on the table".

Yup!

2015 S with QC package, leased on 12/20/2014

Stat date: 7/27/2015
AHr = 64.38
SOH = 100% (thrilled about this, but can it be true?)
Hx = 101.42%
odo = 6,439 miles
charges = 25 QCs & 152 L1/L2s
SOC = 97.1% (don't understand this)
avg batt temp = 91.7 F
292 GIDs (104%)

So can anyone explain why my SOC is 97.1% even though I charged to 100% (no more blue lights) and my dashboard says 100%? Also, can it be possible that the SOH is still 100% after 7 months and over 6k miles? I don't baby the battery at all. We use QC whenever we need it and I routinely charge to 100%, granted our standard method of charge is the 110 outlet in the garage.

This is pretty average. It doesn't charge all the way to 100% because it reduces the lifespan of the pack. Here are my latest stats:

same reason you can't use the last GID in the pack. simply too detrimental to cycle life. 97% is just about where you should be.
