I had the battery checked when I got back and they said it was good but I managed to get it exchanged anyway. In the mean time I installed a battery disconnect switch to keep from draining it in the future. My question is, does this model "new" come standard with an inverter/charger? And while I am hooked up to AC power or using my generator the battery should stay charged and not have this problem right?? Is there a benefit to adding a 2nd battery? I have room and not opposed to doing so.
Thanks in advance for your expertice!!
It is vitally important to make certain what you have. My Trailer(2013 CC 36 CKTS) is equipped with both a WFCO 9865 converter
(AC > DC) with a 3 stage battery charger and a Airpax Dimensions ADI-12W8R3T inverter
(DC > AC) also with a 3 stage battery charger plus 4each 6 VDC Golf Cart batteries wired series-parallel for a 12 VDC output. Both DC & AC power are distributed through a WFCO8930/50NBB distribution center.
If you know the manufacturer of a component, do an internet search to find manuals for each component. Golf cart batteries, while a lot heavier and expensive, have a much greater capacity over time than even the best 12 VDC battery.
For me, we got lucky, in that most of the trailer is DC powered, with mostly only the luxury items requiring AC power. (Refrigerator, Entertainment systems, Microwave, Ceiling Fan and a couple of lights)
It helps to study the manuals to learn how each component is intended to operate. Unfortunately, RV manufacturers do not provide wiring diagrams or synopsis for how these systems are tied together. For that you have to rely on owner manual generic descriptions (if you got it with the sale) and a lot of luck. For the luck part, I improve my chances for success through use a circuit chaser and tester to determine the tie points whenever I am troubleshooting a particular problem, and I always try to employ the KISS principle in this process.
Hope this helps to better understand the difference.
