RESOLVED!
I took the "dtparam=rtc=bbat_vchg=3000000" cut and paste from a vendor's site and saw the same in several other places. The "=" between "rtc" and "bbat" should be a "_". It's odd because I did not see it pointed out here in the couple of threads or on the reddit thread (as far down as I read). The "=" had been looking odd to me but I didn't question it too much.
The proper line in /boot/firmware/config.txt should be:
reports:shows:
And the sysfs files are where they should be.
Does everything look right?
