Ok thanks. I'm not going to get a new one or anything. It charges the batteries %100 if I go on a long drive, which I do plenty of. I was just trying to make some sense of how this thing works.
Are you determining full off of the Xantrex monitor? If so, you have to be certain to have the fully charged parameters set properly, and not just go by time, amp hours, or voltage. Most I have seen have not been set correctly. The amps to the coach battery are the by far the best indicator, and depending on your battery brand and type and the setting can vary a lot.
A full charge on a 50% down battery will usually take 6 to 8 hours, minimum, if the charger has enough capacity to give it all it will accept, so you have to drive a lot. You can fairly quickly get to 70-80% but the rest is very slow for lead acid batteries, both AGM and wet cells.
