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...

Switch on + or - is the same effect. OK to just remove a cable for testing.
I still think you are undercharged or there is a drain on the battery. Is the battery case clean?
What are you charging with and how do you determine when to stop?
If this is a WFCO you probably need two weeks minimum.
Battery is not in case.
Charging with Noco genius g3500
Stops charging when green light goes off that says 100% charged.
Also have an old charger that only puts out around 16 volts. (Reason for newer charger above) If I charge putting in 16 volts...how do I know when to disconnect the charger? Being it takes 3 or 4 hours after charging to get good reading.
