Re: Deep cycle battery boils dry
It takes 14.7 volts to properly charge a Deep cycle battery. 13.3 volts to maintain. Any battery of this type that boils at or above 14-14.2 volts is no good. They will "boil" (Gas) above 14.2 during the charge cycle only. With batt. charger connected, batt full of liquid, check voltage with charger on and see what it's putting out.
However, I've never seen it suggested to leave the caps off a charging battery. The off gas can explode. Good luck and welcome to iboats where there are some experts (not me).
