Hmm another possibilty is that you have a battery with a dead cell this will cause the charger to "see" that the bank needs more charge and ALL the cells get overcharged. I replaced the 2 house batteries in my RV with marine deep cycle batteries from Wamart and in 2 years had 3 maybe 4 go bad. It is an easy check - separate the batteries and check the voltage under load.
