AHr=54.19
SOH=87.27%
384.0V -0.5A
Hx=79.08%
odo=19,736 mi
174 QCs & 739 L1/L2s
min/avg/max = 3.996 4.001 4.004 (8 mv)
Temp F = 63.4 63.7 63.3 (0.5F)
12.40V 0.00A
SOC=68.1%

I think I know what most of them mean . . . Hx being the biggest exception.

What I lack is any idea what some of those numbers 'should' be for a Leaf with these miles/years on it (coming up on three years since initial sale). It does look like I might be close to losing my first bar.

Also, it seems like there are four battery temperature sensors, but I only get shown three (1, 2, and 4). Wondering why that is.

And, how do I grab a screenshot, so I can avoid transcribing the values off the screen? Keep in mind that I bought a smartphone *just* to be able to use LeafSpy, so I'm still working up to having an idea how to use the (Android) GUI.

Your readings are "just as they are" There is no consensual "should be's" with the LEAF or any other EV for that matter. The variance especially on used vehicles simply covers the spectrum of possibility.

You have LS Pro? (IOW if you want real functionality, spend the $20) Then you have access to log files. Connect to your Drop Box account to do so.

Screenshots is a phone question. I can tell you how to do it if you have a Samsung 6

Press and hold Home and power button simultaneously.

I also have LS Pro on my Pixel XL2 which is my "phone phone" (Sam 6 is only for LS so its my LS phone)

That would be volume down and power button simultaneously.

That helps . . . I'll see how things look over time to get an impression of the variability.

I found something already installed called Capture+ that lets me take screenshots:

So you have ahr 80.63%, SOH 87% and Hx 79%. How long did it sit on the dealer lot? Yours kinda looks like a reset but the low mileage can also make those numbers skew. As far as when to log, I log mine every morning on days I drive. It takes all of 30 seconds to do so, a bit more to transfer but I do it mostly because it gives me a daily record in a database I can look at. I generally don't have LS running except for specific observations, tests and fast charge sessions.

LeafSpy Pro is my next step . . . wanted to try LeafSpy Lite first to make sure the rest of the pieces were up to it.

That looks to be about five months between the lease return and my purchase, with an auction during that period.

I mostly wanted to hear if any readings might be indicative of a problem. Sounds like not from others on this thread.

One thing I see that seems a bit high is the number of Quick Charges (174). I've done 14 of those in the nearly six months I've had it (say 2.5 per month). So 160 were done in the previous 18K miles and ~24 months, at a rate of 6-7 per month. But the previous owner put 9K miles/year on it and I'm on track for less than half that (4K miles), so I guess that tracks pretty well. Plus I can L1 charge at work so that allows me to avoid QCs more that I suspect the original owner did.

Try to keep the state of charge under 100% and the battery as cool as possible and you should be ok.

If you drive that little, the car should work for years. I would keep SOC between 25-70%. Where exactly I will leave that up to you. You want a bit more for contingencies and I would push the upper limit to 80-85% in Winter but only if you are getting home at 30% or less.

Always good to hear advice from someone with more experience than me . . . thanks Dave.

lol, no
press and hold a button or two for 2 ~ seconds. The button combo varies by phone and android version so it is best to just google the answer.

"Nearly" all new Androids are the same. If you have an older one with dedicated home button then it would be home+power. In all cases, the key (pun intended) is to hold both until the screenshot is captured which will take a second or two.

I gather that the V and A numbers after Hx are for the traction battery. 380-something volts seems typical for voltage but I see both negative and positive numbers for amps. Negative I take to mean the traction battery is discharging (topping up the 12V battery I suspect), so positive would mean it's charging, yet I see positive numbers there when I'm not charging (in fact I've yet to use LeafSpy when charging). So what would cause the positive numbers besides charging? Or if I have it backwards, what would cause the negative numbers besides charging?
