I begin by saying I am a Newbee to owning an RV. The beginning of Winter I removed my Two new 12V batteries and placed them on Two cut 2 x 4s to store in the garage. The weather has warmed up, plus talking to a friend I made the decision to put them back on the RV (New, and we have not taken out yet). Connected them in parallel and turned the Battery Disconnect switch to OFF and unplugged the electricity ⚡️. I then checked the Control Panel, but nothing worked. Are my Two new batteries destroyed by removing them and storing them in the garage? I never purchased a trickle charger for them. Please, any knowledgeable owners in this Forum I need your input. 🥴🥺
