Just an FYI and "library log"...
My coach batteries expired on my last trip (the week after warranty expiration).
After shopping around, I chose the Costco/Johnson Controls "GC2 golf cart" batteries for ~$60 each.
Based on an apparently credible post, these batteries are actually US Battery model US-2000 rated for 210AH (105 @ 12v).
I decided to sanity check my Xantrex Freedom 458 inverter/charger settings.
I found the settings to be the default settings, which were wrong.
--Battery bank was set for 400AH, I set to 600AH (6 batteries X 105AH). I believe this "tailors" the charge cycle.
--Idle was set to 5A, Xantrex website manual now contains a footnote for a "0" setting for RVs.
--Battery type was default set for "wet cell", but take notice if you ever use an AGM or Gel battery, this setting must be changed to service a critical difference in the way such batteries are charged.
Please let me know if I missed something or messed up the math...
