Curious as to what size and type batteries class A owners use for house batteries. Our manual does not mention or explain how to calculate requirements. Doug
As above, get them checked. If they have been giving you good service just replace them. Are you deploying slides connected to power or just on batteries? My manual states to exercise the slides while on shore power or gen. Moving a FES takes a lot of power. I try to help by opening a window while operation the slides a lot of air has to be accounted for when going in or out.
