Pretty much essential with AGM batteries if you want them to have
a long and happy life.

Yea, have used them on two boats and love 'em. Be sure not to mix with
other
types. A three phase "smart" charger is nice to have too.

Does anybody have any direct experience with the AGM (Absorbed Glass
Mat) batteries? One manufacturer claims that these batteries are
completely sealed against fumes and don't require venting. Does
anybody have these on their boat?
