My 2010 Bighorn has the 2 original 12 volt batteries. This spring is the first time they seem weak, wouldn't put out slides when not plugged in. I can't believe they have lasted this long. We have always kept the RV plugged into an outlet in the shop when not in use. I'm shopping new batteries and would like some suggestions. I'm reading that you should not leave the RV plugged in but they have lasted forever doing this. Does the RV use a battery maintainer that doesn't over charge being plugged in for months at a time? Any info on battery life would be greatly appreciated. Also what battery would you buy? Thanks Terry
