There are pulse chargers available that will help de-sulfate a battery if
that is the problem. Before using one, you generally want to make sure the
battery is fully charged. This device will pulse causing the sulfating to
be removed from the plates.

My trolling motor battery seems to not have the longevity as it used
to. It seems like I am only out on the water for a few hours before I have
to move the speed controller from a 1 to a 2, and so forth. Is there
anything that I can do that will help bring the life back to the battery?
thanks in advance
