Is this noraml for a battery?
I charge house battery up to around 12.75 Has a battery disconnect switch (installed on neg side) in about two weeks later, I test with same volt meter and reading is 12.18 volts. Is this normal...

I don't know if there is any such thing as normal in the rv world. Our last motorhome we could charge the batteries, hit the disconnect switch and they would stay charged for several months. Our new motorhome they go from 12.7 to 12.5 within 2 weeks with the disconnect switch off. Forest River says that is normal and state that small parasitic loads will do this. Yet they could not tell me exactly what those loads are. About the only thing you can do if so inclined is to pull individual fuses and put an ammeter in series to see which circuit is still pulling current with the switch off.
