I know how to do that, I can do that. Does the OP have a battery monitor or a Fluke? Does he have a $3000 battery charger? Just put the batteries in the rig and use them. The PD9245 has enough stages and smarts to keep em working a long time without damaging them. Eventually, in the right conditions, his PD9245 will achieve that charge state but it is nothing to worry about at all, zip. RV's never achieve perfect conditions except for the most OCD among us.
There are a gazillion web pages out there, some are by really capable folks and some are just hot air. Many of them have little to do with the reality of using and working batteries in the RV. The OP has a LP fridge so his batteries should go around 5 - 6 years, perhaps a tad longer with luck and no "bad" discharges. Of course I'm guessing he has installed all load and charge to one battery POS and the most NEGative ground is on the other.
