Yes, I believe that this is the meaning of "SOH" on LEAF Spy and similar devices. I think, but am not sure, that they use 66.25 Ah as 100%. I am reluctant to wade through the massive LEAF Spy threads since I use the relatively simple Leaf DD instead.
No.
It is an integer value reported via the Car CAN.

Although it does tend to be close to % capacity, and many have called it that incorrectly, there is nothing to clearly document what Nissan considers it to be.

Like all the other values on the CAN, Nissan has refused to document any of them.
All we have is a lot of reverse engineering guesses by a lot of smart people.

LEAFDD is no longer in production.
Have to find someone willing to sell one.
I haven't used mine much, but currently not willing to sell.
I should start using it more as it does give a great way to measure battery impedance and is the only device I have that communicates with the EV CAN.

I purchased a used LeafDD from someone here on MNL but when I plug it in all I get is gibberish :( I cycle through the various screens but the only one I can just barely make out is one that has a large number on it, maybe the GIDs?? On a full battery it started out at 204 if that makes sense and quickly dropped as I drove. I tried reseating the plug and wiggling wire but I can't really read anything....any ideas :? is the maker still around for support? the way it is, it's basically worthless to me :(

BTW I'm trying to use it on a '12 Leaf SL if it matters.

LeafDD should have no problems on a 2011/2012. There was a problem with the display early on (I had it with LeafDD #8) that required re-soldering of the display header to the PC board; more like re-flowing to be honest (although I had to add some solder). You might take a look at that if you're feeling adventurous.

I tried the LeafDD on my '13 and it's the same, gibberish. I'd post a photo of it but it doesn't look like MNL supports photos other than on a remote site, which I don't have. I kind of looked at the back of the board(since there is no back?? I take it this is normal?) and all the solder joints look OK but I do wonder as it has no back if it could have gotten a static electricity jolt to scramble something?? It seems nicely made but again it's hard to believe there was never a back.....seems very venerable to shorting out or static discharge.
I think I'll wait another day and then PM the maker(gregH) to see if he has any repair options available, then again maybe he's not supporting them anymore since he no longer sells them....

I have a Lincomatic multi-page meter for sale if anyone wants one... I no longer have the Leaf so have no need for it... Make me a reasonable offer and it is yours.

Just because solder joints "look OK" doesn't mean they're OK. I'm talking about ALL the pins on the OLED display header: they need to be re-flowed/soldered and checked for shorts afterwards. He hasn't sold these things for a couple of years (sold everything he made), and he basically did it "out of the kindness of his heart"; he didn't really make a profit on these things (they were much cheaper--and better--than alternatives at the time).
