The car has not been driven since I did the voltage readings.
Thursday - 12.41 volts
Friday - 12.39 volts
Saturday - 12.37 volts
Sunday - 12.36 volts
Today - 12.34 volts
I don't understand why the drop from day to day is less than my initial reporting.
You charged the battery.
There is a function of terminal voltage vs % capacity or "state of charge", a table of these readings are on the table on page 3 of this PDF:
The current with the key off is less than a C/100 discharge rate, for our batteries, so use that curve as a reference; it shouldn't be far off.
This voltage is fairly independent of the size of the battery; it's a function of the chemistry.
I would do an equalizing charge to the battery, and see if it will hit a 100% charge level.
If you don't know that term, look up how to do it here:
