You probably have one of the old "boat anchor" chargers, suitable only for throwing overboard. Transformer and couple of diodes was the extend of the technology used in those, they would run constantly at around 14 - 14.5VDC without regard whether the batteries needed that high voltage, or not.
You should charge your batteries with good three stage charger which will "float" your batteries when they reach a full charge. Progressive Dynamics makes a series of very good RV three stage chargers (PD models) with various current capacities suitable for single batteries or battery banks.

Vote #2 two for Progressive Dynamics. Variable "3 stage" charging, plus desulfates the batteries too.
