I have had lots of batteries not only in my travel trailers but when we had a 47 foot sail boat that we traveled on. In my experience most alternators charge at 14.4 volts and most chargers charge at close to 13,8 volts. As previously said a battery should be full charged at 12.7-8 volts. If it reads higher than 12.8 volts it is due to the charger inputting 13.8 volts and once disconnected the battery will settle down . A smart charger will shut itself off until battery drops to 12.4-6 volts and then start up again. You should be ok for a few days but if I were you, I would install a send battery with a boat 1-2 both switch. That way you use one battery until its down and still have a freh one for extended stays.. Have fun. as a side note, next time spend the extra for a glass mat battery. They last longer, charge quicker and are superdependable.
