If connected in parallel then they will act as one battery and will charge
and discharge at the same time keeping both batteries equal.
Connect + to + and - to - on the batteries. Connect your equipment to
either battery + and -. Connect your charger to either battery + and -.

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?
