Hi Alex H, Jeff M is just about right on the money.
The only thing that I would have a difference of opinion on is the equalisation.
As Jeff put it, if the charging is stopped before both batteries are fully charged and I might add here, even when that ARE fully charged, there will most likely be a small difference in voltage levels between the two batteries. Unless there is a problem with one or both batteries, there will only be a very low current flow between the two batteries while they equalise.
If there is a problem with one of the batteries, you will soon find out as this is when the equalisation will not only be high but unless you find out about one battery having a fault, you will very quickly have two stuffed batteries but being honest, this is not something that occurs all that often.
Although not recommended, paralleling of batteries is a common practice but it is usually done using two identical batteries. Even then, using identical batteries, there is still going to be a slight difference in battery voltages.
Cheers
