"not going below 12.0 volts" is the resting voltage. You can only accurately measure it when the batteries are neither being discharged or charged and have had some time to sit there unused.
This.
All batteries show lower voltages when under a load, with the extent of the lowering being a function of both the size of the load and the chemistry of the particular battery. This is normal, and NOT a sign the battery is discharged to any particular degree.
