My 2000 rig is fitted with a Heart Interface Freedom 25 inverter/charger and a Link 2000 controller. I think the system is applying too much juice to charge the batteries (my house battery bank consists of 6 x 8D batteries) because I am getting a lot of liquid coming out of the batteries which is messing up the compartment. I am sure that the batteries were not overfilled.

I noticed this problem when the storage warehouse where I store my coach started offering power for coaches to maintain batteries. It is only 120V, 15A max so I set the charger to the lowest setting (5 amp). This feature is called Charge Sharing in the manual (avoids tripping the source breaker by limiting current). The charger transitions from Charge to Accept to Float but even in float the batteries emit a lot of liquid out of the vent caps.

In my mind, the batteries on float should not do this. I have checked the settings (set for wet cell batteries) and they seem OK. I did notice that the battery bank capacity was set to 220 Amp hours. It seems that since I have six 8d's, the capacity should be set to something like 1200 AH (6 x 200). According to the manual, this setting is only for estimating the amount of power remaining in the bank under load. It does not appear to affect the charging process. Any ideas, suggestions?
