WFCO Converter/Charger won't go to Float
My son's 2017 Cougar fifth wheel is headed out on a long trip, so we went through it getting everything ready. First problem was fried batteries, two six volt golf cart batteries. He hadn't watched the water, and they were ruined. We've replaced them, but in checking to make sure they weren't being overcharged, I have noticed the WFCO converter is just staying at 13.6 volts and never goes into 13.2 float even though the batteries are charged. I even left it charging overnight with all 12v loads off and measured them this morning and it was still at 13.6v. So two questions: First, from what I've read this "stuck on absorption" is common on these WFCOs, as they app so assuming it's operating properly even though it's a three stage charger, how bad is it for the batteries to have a long stay at 13.6 v charging? Second, I'm used to my much higher grade Xantrex Freedom SW2012 Inverter/Charger which always takes my battery bank down to float. We aren't going to get something like that, because he has no need for an inverter, but if we come to the conclusion that we need a better charger/converter, which ones would you recommend? At $250 a pop i don't want him to have to soon replace these new batteries.
