Boiling Battery Water

I own a 2009 Fleetwood Wilderness w/ a power converter panel made by World Friends Co., model # 'WF8955AN w/ Plastic'. It's called a Power Converter w/ Panel.
The issue is that if I have the trailer connected to shore power for about 8 days, it boils all the water from the battery. (I have one 12v deep cell battery.)
When on shore power, I read 13.6v on the battery. When I have the battery on the bench and charged, it reads 12.6v.
None of my other vehicles have a water usage issue like this. I don't think this is normal.
I'm about to start researching the power panel.
Can anyone shed some light on this issue?? Is this normal for a travel trailer or do I have a problem w/ the charging circuit in the power panel?

  • if battery is going Dry... the charger/converter is defective.. and in 8 days,,, its very BAD..

    mine charges at 13.7 volts.. but after 24 hours or so.. it throttles back to 13.2 volts. and stays there for weeks.

    in the past year.. ** when new battery installed ** I have not needed to add ANY Water to the battery.
