14.95v is over charging
Voltage regulator will cause alternator to output above 14volts for a few minutes just after starting engine, this "re-charges" the battery back to 12.3-12.8volts.
Then voltage regulator will drop voltage to the "maintenance level" of 13.6volts
Approx. 1 volt above battery voltage will maintain the batteries voltage/amps.
If you are reading above 14volts at the battery after a few minutes of the engine running then you are "cooking" your battery, fluid inside will start damaging the plates and battery life will be shortened significantly.
Battery voltage engine off, for at least 1 hour, should be above 12.2 volts, 12.2 volts means battery is at 50%, 12.8v 100%(new battery)
At 50% a very cold morning would probably cause a short slow crank or no crank.
Since the voltage regulator "reads" battery voltage and bases alternator output voltage on this, a battery with lower than 12v could cause 14+ volts in the system.
