After much surfing I found a couple of others who also had their WFCO charge at high voltage. When I replaced the batteries they were bulged at the sides. I replaced that WFCO with a free one from another camper who had his sitting after replacing it with a LiFePO4 charger.
wfco chargers are POS and known for boiling batteries dry and/or never going into bulk charge mode.
I now have both reverse polarity fuses pulled, since we have no problem keeping our SiO2 batteries full with our solar and have been charging solar only since last February. How did I know to pull the reverse polarity fuses? Answer: because our batteries are not the only batteries a WFCO has ruined, and those other owners don't trust their WFCO either.
Enjoy,
