Generally voltage at the battery (after 10-20 min of alternator charging) should be around 14.1~14.5v. If it''s more than 1-2v volts lower, then probably bad alternator function (which can be caused by a loose or deteriorated belt - may not need a new alternator) or some hefty accessory usage.
Resting, fully charged 12-volt batteries read at around 12.8-12.9 volts. Counterintuitively, a battery is dead at 12.0 volts (not zero). The minute you apply a load to a battery at 12.0 volts, the voltage plummets and nothing happens. So, a reading of 12.4 volts on a resting battery means it''s about 50% charged. RV Battery Voltage Overview
