Is there a conventional definition of voltage? If so, what is it?

How about energy per unit charge?

Is the definition valid in a region where there is both a rotational and an
irrotational electric field?

Yes, but in the presence of non-potential voltages, you can't speak of the
voltage difference between point A and point B without specifying the path
that the test charge takes from A to B.

Does the voltage of a battery differ from the
terminal potential difference?

It does not differ in ordinary situations, such as situations where
Kirchhoff's laws apply.

OTOH if the battery is a region of changing magnetic fields, all bets are
off, as discussed above. There is no "terminal potential difference" and
one would have to work pretty hard to define a nitpick-resistant definition
of "the" voltage of the battery.
