Nothing special, but I do have a question about battery
chargers. We have two battery
banks, a starter bank and house bank. The starter bank has 3 reg marine
deep cycle batteries, and house bank has three 8D's. When we anchor
out, I usually turn off the starter battery circuit and of course just run the house batteries. As an additional measure (to make sure I have back-up starting capacity), I cut out one of the big 8D house batteries....just in case. We also have a wind generator
and solar panels
, that are wired through charge controllers and/or switches to the main house circuit....but I don't think these are part of the question.
Question is...the way we have it wired (two banks and a charger) even though the starter battery is out of the circuit, it still remains in the charging
circuit...the same holds true with the 8D when I isolate it. Now the good part...even with batteries isolated from the main circuit they are still connected through the charging
circuit...wouldn't this mean that isolated and turned off batteries are, in actuality, still in the main circuit through the charging system? If so doesn't this negate the isolation system because the batteries are still part of a circuit although not part of the usage circuit.
BTW we have a Professional Mariner charger
, and Perko switch isolators (no affilitation)... Do these chargers have some kind of diode protection circuit to prevent using battery power that is not in the main circuit but still in the charge circuit? Whew...I think I understood what I said.
