Folks, "Swimmer" seems to habitually post a lot of threads with the SAME issue and no change in the bad habits no matter how much "counseling" from many good electrical folks here.
Swimmer for some reason spends all of their time "testing" by running down batteries, then taking the "bad" batteries back to the store to get new ones..
From the posts I have seen, swimmer has multiple RVs without power from the stories I have seen and from what I gather uses the batteries then leaves them sit for periods of time discharged or recharging them with a small trickle charger which would take months to fully recharge..
Doesn't seem to have a clue or is pretending to not have a clue about electrical, batteries and such..
Save yourselves the grief of running down the rabbit hole again..
