RV Voltages too high while charging
I have a problem and have been wrapping my head around this for a few days. I have four 100w Solar panels, and a Morningstar RJ-45 programmable charge controller wired to batteries. I have Four In...

Is that to be considered "recent"? Not sure. All I know is "multi-stage charging" has been around a lot longer than I've been RV'ing. I admit I am not at all familiar with linear type chargers, or single voltage chargers, but I can't imagine flooded lead acid battery technology has changed a whole lot.
Anyway, I doubt any of this has to do with establishing proper charging voltages. All I know is what I've seen first hand. I do not cycle my bank deeply, nor do I let it sit in a discharged state or any real length of time. But I am seeing the effects of regular over-charging. Self discharge has increased by leaps and bounds, and resting ocv's have dropped noticeably. I doubt anyone recommending I charge at 15.3v on a regular basis is going to reach deep into their pockets and cough up the near $700 to replace my bank.
Sorry that was a copy and paste. I agree IUI charging has been around for a while. The reason i even brought up IUI charging is because of the OP interstate battery charging profile. I was able to get a hold of a upper level tech and he admitted that they screwed up there IUI recommended charging profile. But i talked to a lower level tech and he was convenced that the profile was correct. I find it intrusting that Rolls , Fullriver , US battery , GMB and provide charging profiles for IUI charging. I use this charging at work and my RV and has worked well for me. Sorry to here about your batteries. O and MEX the batteries in question ARE hybred antimony pos calcium neg cunstructed batteries.
