Batteries Overcharging ?

[GoPackGo]

I have 2 group 29 house batteries that are about 2 years old. I just checked and they are hot and appear to be boiling off fluid. Can this be caused by one (or both) bad battery that won't take a charge, resulting in the charger continuously charging at a high rate ?

I added a lot of water last week but I just thought I was behind on my watering.

I just flipped the main battery switch to 'off' until I get this figured out. They were getting pretty hot.

I have a 2014 Heartland Bighorn. Will have to call Heartland and ask where they hid the converter/charger.

Thanks for any help on this.

converter is behind the wall in the storage on the door side

Measure the charging voltage and post it up.

Then disconnect and separate the batteries and let them sit 24 hours and post the voltage still resting.

Yes, a bad battery can cause the charger to overcharge. The only feedback the charger gets from the battery is how much current it is drawing, so a damaged battery can keep telling the charger it needs more charging.
