My chevy lumina 95 3.1L V6 has its alternator's charging output varies between 13V. to 14V. during a day of normal driving. Is it okay or not?

Note: The alternator's cables are all checked fine.
Thank you in advance!

    Load the electrical system; Let it idle, turn on the a/c, blower on high, headlights on bright, and any thing else you can think of. If the gauge falls below 13v, have it replaced - If not it doing fine.
