Battery condition
In the big picture of the electrical system in a 5er, if we are plugged in to shore power, does the state of charge or discharge of the battery make any difference?

5 yrs sounds about right for lifespan. A good battery shop can load test it for you and let you know how good it is. I take ours out during the winter, place on piece of wood in cellar, and charge it @2amp rate 1x month for 24 hours. Add distilled water if it needs it as well.
