New owner: 2012 SL new battery, any concerns with these Leafspy #s

And so we go from "possibly dodgy pack" to "good pack, too long commute"!

Hi again, a couple months ago I posted my Leafspy numbers, posted again below. The AHr, SOH and Hx have dropped and am wondering if this is normal and if the following could be cause for this:

- Winter driving in Los Angeles
- L2 charging. I was previously mainly doing L1 charging and didn't see a drop. A month ago I started doing L2 for all charging at home and noticed a gradual decline after that. But again, not sure if it's because the weather got colder.
- (Me being paranoid) Was my battery reset? I confirmed with Nissan that a new traction battery was installed in March 2017, but I'm still wondering if it could have been reset even after the replacement. How long after a reset do you see a drop, and how much of a drop do you see?

Thanks!

The second reading was taken with the car fully booted up, right? Readings taken during bootup can be unreliable. Otherwise that does seem to be a significant loss for a supposed Lizard pack replacement. A QC session on a cool day may raise the SOH, but we don't think that this boost is a real increase in capacity...

Thanks @LeftieBiker

The second reading from 1/28 was actually taken while the car was off but charging.

However, my reading from the day before while fully booted up is similar:

1/27/19
AHr=57.526
SOH=90.17%
384.14V
Hx=77.73%

Would you say that the car's pack gets hot (8 bars or more) regularly?

No not at all. It's usually in the 4-6 bar range for temp during my 40 mile one way commute. I've only seen temps that high after the handful of QC's I've done on long trips.
