Q: Normal operating voltage?

asked by on

I was just curious as to what the operating voltage should be on my pickup. Currently, my voltage gauge in my dash shows my truck runs at about 14.5 volts. I am getting the battery tested today to make sure my battery isn't on its way out. (Getting slower to start cranking) so i was just curious if this high of voltage is normal, or if i should be expecting an alternator or other problems shortly.

My car has 250000 miles.
My car has an automatic transmission.

Most vehicles require at least 13 volts to operate properly. Ideal voltage is 13.8 - 14.4 volts. 14.5 volts is completely acceptable and should cause no issues.
