RV batteries not charging up to 100%

Ok. It's been a couple of days and everything continues to go as it should. The batteries are staying cool to the touch. The Magnum system is alternating between Float charging at 13.4v and Full Charge (rest state).

Great you got that ironed out.

I totally agree with you. I was surprised when I saw that reading and there were no warnings.

For what it is worth: Remember that the older batteries get the harder it is to charge them to 100%. Once they get to 4 or 5 years old, they may never show 100%. You really should do s specific gravity test on each battery to be sure of battery health.
