What is your question?
OBD not working after miles of driving and the generic drive cycle has been done 3or 4 times too. Same thing last year; but new battery was bad and was just replaced again. Could the OBD itself need repair. No one discusses with us; everyone just says keep driving. But I need to pass state inspection. Not sure can get a second waiver
How long has your 1996 Mazda Millenia had this problem?
2 years now

*Scan test* will reveal if any issues exist to keep monitors from completing during drive cycle. It is kinda unusual for the battery to fail 2 years in a row just before annual inspection is due.. Good luck!
