I have a question.

After 4 years I replaced a B&C battery.  heavy amp loads as I always have a
flashing landing light.  Anyway I have always had a 200 MA charger to keep
the battery topped off.  What I would like to know is how much amperage does
one need to apply to keep a 27 ampere hour battery topped off. Or better yet
what amperage and voltage ie watts is needed to top off a battery on a
continuous cycle?
