Each sell of a fully charged battery puts out 2.1 volts or 12.6 total so with the car running and charging you should read 13 or more volts. Everyones opinion on the forum counts, lets not turn it into a debate though, but try to stay on topic.
The important thing to do is to clean your battery connections with a solution of baking soda and water, apply dielectric grease to prevent further corrosion, re tighten everything, and see how it goes from there.

On car of old, there was a 12v supply provided to the Alternator via a switched source.... So as soon as you turned the ignition on bam the alternator was provided with power to produce the 14v it made..
On the more modern car, this is not so... The PCM provides a varying voltage to the alternator so that it can produce power...
When you start the car you'll notice that the Voltage takes a few seconds to come up... The first few seconds you are running off the battery, then the PCM supplies powert o the alt and poof 14-14.5v( the power applied can vary )
Clean the battery connections first before you attempt anything else

The above post says it all, now I know why I see the lights are dim at first and then full brightness. I cleaned the post good, put some battery term. protector on them and it seems to be doing okay right now. Thanks for the advice everyone
