Update: I unhooked the charger today so I will let you know tomorrow what the voltages are for the pack and individual batteries. I checked the water levels and all are covering the plates, but 2 out of 4 look like they could use and little added to them. Also, while I was examining them, I noticed like a gurgling/boiling noise coming from 2 of the batteries on tje passenger side as well. Is that normal? I tried to find the date of the batteries but can't seem to find any markings on them?
