If I'm not mistaken, you're just describing "background charging": The car will top up the pack at a relatively low amperage while cruising, without lighting any bars on the charging side of the display.

If you're sensitive enough to your normal "fully charged" (or "pack disconnected via the big-a$$ OFF switch") lean burn window, you'll notice it's harder to enter or hold lean burn near your usual load limit when background charging is happening. Once the pack is back up to ~19/20 bars and background charging ceases, lean burn is easier to achieve/hold.

Final note: my pack has 168,000 miles on it. I'm totally impressed with what I've seemingly achieved with this cycling process... I've probably at least doubled the capacity, maybe closer to tripled
That's great!

So, I guess only time will tell if my pack's revitalized performance will actually last...
I hope you'll keep us posted. I haven't driven my car for several weeks - since I reported my results earlier in this thread. (I realize my infrequent car usage is not ideal for battery health.)

Now I'm waiting on a few parts before I install my grid charger/balancer.
