The Sea Ray manuals show that your boat is a 370EC (Express Cruiser), rather than a Sundancer (DA).
You have a total of five (5) batteries and three (3) battery switches. I'm guessing that you have one battery which is a starting battery for your generator. Then you have two sets of two batteries each for each engine. I would guess that the battery switch selections for the engines are the typical off, batt 1, batt 2 or both selections.
Are you saying that all five (5) batteries are failing in a short amount of time?
How often are you checking the acid level in the batteries?
How often do you have to add distilled water?
Does your battery charger/convertor have an amp guage? If so, what is it reading as a current output?
BTW: A 30 amp charger was the standard model put in your boat by SeaRay. To me, that is a really light duty charger considering that you have five batteries on board and you have a lot of 12v lighting, etc. that can put a heavy draw on your batteries. Additionally, if it is the original charger/converter, it is thirteen years old. I would be very suspect of your charger.
So far, with the exception of one poster, all of the responses to your inquiry have been from owners of boats that are much smaller. I believe that I saw Four Sons (Gary) post something about a replacement charger that he put in his boat. Possibly you should try to contact him for assistance.
