jeff:

it is usually unnecessary to use a charger during the week if the van is
driven most weekends.

although an ordinary charger is not a constant current source, and the
charging current naturally tapers off as the battery reaches full charge,
there is a real danger of overcharging the battery when used in place of a
true trickle charge unit.

more is not always better.
