The battery that was previously low on electrolyte was low again so I removed it and now have only two RV batteries temporarily connected to an Xantrex 10 amp charger which brought the two RV batteries back up to ~12 volts.
Elsewhere you said -
"The battery loosing electrolytes is dated 01/06 while the other two 01/07"... so along with the fact you weren't able to restore these batteries to any more than ~ 12 volts that would indicate these 10+ yr old batteries are pooched, regardless of whether your PD converter works properly or not.
