Fully charged batteries should read around 12.8 to 13.1 volts after several hours disconnected from loads or chargers.
Under heavy current draw, seeing battery voltage dip to 12V is not unusual, but when the short duration draw is done, the voltage should climb back to near what it was before the drain in a few minutes.
A lead acid battery that reads 11.9V after sitting for several hours disconnected is near total discharge.
