Running voltage should be 13.6V - 14.0V

Looks like the battery is in good shape. It read 14.2 with the car on. I'll have to dig through my records to see when it was last changed.

With the engine running you're measuring the output of the alternator. You measure the voltage of the battery with the engine off and it will be more accurate if you let it rest for at least an hour first.
