Just for info, the max standing voltage on a fully charged battery (SOC) is 12.7-8. Anything above that is a peak voltage from being charged.
Voltage reading under normal starter load should be not lower than 10.5
The larger the battery, the higher this voltage reading will be.
While jumped to a large car battery, the voltage could stay near 12 volts.
On edit
Standing voltage on full charge after setting 24 hrs, can be 12.7-8
Age and condition of battery can vari standing voltage from 12.8, down to 12.3, and still perform ok.
