Are you driving your rig a lot? Sounds more like your alternator output is off.
Is your inverter charger going into float mode?

The majority of deep cycle batts utilizing golf cart 6 volt in the configuration, are to be charged to 14.8 volts, and held there for between 2 and 4 hours.

Now I know that many of you disagree with this but the manufacturer's are the ones that recommend this, and those of us that follow this recommendation find maximum proficiency in their batts. This also negates the need for any equalization charges, and a 10 year life is expected.

I use BatteryMinders on mine. I have a couple of umbilical cords going to my MH and have found I have to set the my model #12248 to AGM mode to get the 13.20 volts Torjan wants for a float voltage. I check them about once a week and only see tiny little bubbles floating in the mineral oil. BatteryMinders go into the desulfate mode when they sense a full charge.

I had the same problem when my 40DP was brand new. Went through two sets of coach batteries before my dealer contacted the inverter/charger manufacturer (Dimensions) and was told that the charger's amperage draw was set at 25 amps which was too high. They had me lower it to 15 amps and it hasn't been a problem since.

It would help you get better responses if you added the make, model, and year of your coach to your signature line.
