Thanks for the help cwernda. I started with the Lite version just to make sure it would work but do have the Pro version next on my list (want to reset the TPMS once I get new wheels/tires).
Hopefully a few more data sets will help me see how soon I might hit that 83%. Wondering what frequency makes sense for that . . . is weekly too soon? I imagine there's some noise in the readings that would make trying to use too-close-together data points relatively useless.
For me, in the Pro version, the help is in the 3-dot menu, About & Help, Application Help.
The problem is AHr, SOH and Hx will all fluctuate somewhat with usage. So, even taking weekly readings could mean you're taking them at the "wrong" times. I have an OBD2 extension cable plugged into my Leaf at all times. I usually connect the dongle to the cable when driving and I'm ok w/leaving it connected when in the garage. I may disconnect if I park it outside/out in the open (out of paranoia for security reasons since someone else can connect to it and do whatever the dongle allows).
I don't recall how long my SOH readings were around 84 or 83% before I lost my 1st bar. Even now, my SOH readings are fluctuating between 82.xx% and 83.xx%, mostly around 82.x% and still at 11 bars. I'm near 65K miles in a warmer part of the SF Bay Area.

sounds right. Long ago, you'd have to install adb and use commands like at https://stackoverflow.com/questions/277 ... the-screen
