Swapping out both house batteries - anything need to be disconnected?
I've got a 2011 SMB Sprinter RB110S build, and will be replacing both old deep cycle house batteries with new 100 Ah AGMs, leaving the newer AGM starter battery in place.
Do I need to disconnect anything during this process, or can I just pull the cables off the old batteries and connect the new ones in the same pattern? I vaguely recall reading something about having to protect the solar charger but can't find the thread.
