I have a current problem with my batteries. Its been at storage for a couple weeks with the battery offline using the OEM disconnect switch. On Sunday I bought it home to get it ready for a camping trip Thanksgiving weekend. When I got home Monday night from work the batteries are dead, same thing last night I went to check them this morning and dead. I just can't understand how the batteries can sit just fine at the storage.
I had the coach running on generator last night just to charge batteries. Brought it up to 13.4 and then turned off batteries. Our coach is about a month old since we have taken ownership I see that we have Interstate batteries and the dealer had to wire up a second battery when we took delivery. Since these batteries have been completely dead for two days now after charging and discharging do I need new ones?
