    Gary;
    I have a Progressive Dinamics converter 9100 with the Charge wizard in my 07 5th wheel. I have 2 6volt batteries in the trailer. It does the 14.4 charge, drops to the 13.6 and then the mantanance charge 13.2. with the jump to the 14.4 as a desulphater in the program.
    Question is, should I pull the power and let the batteries just sit and due a normal discharge over acouple weeks or just leave the power on? Water evaporation is very minumal with this system.
    What say you?
    By the way I have read some of your advise on some matters.
    Thank you.

    would 4 6volt golf cart batteries be equal or close to the same amps as 3 12volt batteries to be used as house batteries.
