Jeff is correct. If they are different sizes and different ages, you could
possibly undercharge one and overcharge the other. Do a Google search on
marine batteries. Lots of good info.

In parallel, as others have said. However, if this is a long term hookup,
make
sure they are similar batteries of the same age. And make sure the
connections
are clean and well made, because if there is a bad connection, it will
have all
the appearances of a good setup, but will only have half the power.

How should more than one battery be hooked together
as a supply for an inverter? Does it matter which battery
in the group the battery charger is attached to? It will
be an automatic charger. Will all of the batteries drain
down and build back up pretty much as one big battery,
if they're connected in the right way?
