I, too, have recently joined the ranks of swappleshooters. Here's what I did. I had an original 2011 battery with 58% SoH. It was painful to see that 8th bar disappear. I found BatteryHookup online that was selling removed LEAF batteries with 60-70% SoH packs. They sent me two packs by mistake, so it only cost me $2k for two. I proceeded to swap each pack into my car and drive them (even in angry turtle mode) and use LEAFSpy to gauge the relative health of each cell as they discharged. There is a trick in "angry turtle mode" (P3102 error due to unpaired pack) where you can get the car to go fast and use up to 40kW. Mashing the throttle and holding it in one position will temporarily allow you to drive well above 28mph, but only for one minute at a time. Then you have to return to a stop, mash again and go. It works pretty good in city traffic with lots of stoplights. Once I had rated all the cells in all three packs, *orig, swap1 and swap2, I proceeded to figure out what cells would go into my "Franken-battery".
After two iterations, yes, two complete tear-downs and rebuilds with cells swapped around to produce the highest amp-hour rating, I got the Franken-pack working with the original LBC.
Here's the rub. I am also waiting patiently for the increase in range and maybe get a bar or two back. I'm glad to hear the LBC will slowly learn range. I guess getting bars back is not so important as range increase. My SoH has increased over the past five charge cycles from 53.8% to 54.10%. It's slow, but knowing someone else is able to see the LBC learning curve gives me hope.
I think I read somewhere else here that a historical reset to 12 bars is the fastest way to reteach your LBC. But that will cost $ unless you have Consult III+ and "the card".
