Right.

Or avoid the need to argue by saying that the
current is negligible.  That is, even if you
think the current is nonzero, making it ten
times bigger or ten times smaller won't have
any meaningful effect on the quantity of
interest (the battery voltage).

(If it does have an effect, either your
battery or your voltmeter is severely broken.)
