Battery bank problems SM with 13 batteries

eric <kimberlite@...>

On our trip home from St Martin last week, we discovered that most of the liquid in all the sealed maintenance free batteries had boiled off. I did not realize that under the labels there are plugs where water can be added. In any event all the house (12) batteries
have to be replaced.
We have a 175 amp alternator and 30 and 100 amp Dolphin chargers.
I spoke with Dolphin and they said that the 30 amp charger is too small for the bank and it probably cooked the batteries as it saw the bank as always needing a charge. I plan on having the alternator checked and then speak again with Dolphin when I install the new batteries.

Kimberlite usually is in a marina somewhere and plugged in with the 30 amp charger running.
Any thoughts on my problem?
