You don't mention what age or model of ProMariner. Their older ferro-resonant type chargers are notoriously inconsistent, unreliable and are responsible for destroying many batteries or at least severely shortening their life span. Also note in the photo below there is no 3rd party certification (UL) on the label as required by ABYC and Transport Canada.

If this is the case, buying a more modern "smart" charger should be near the top of your shopping list.
