Default Alternator/battery questions...

I've just taken my bird outta storage from the long cold winter. Battery was on a tender the whole time. Fires up right away and went for a 30 mile spin. Voltage gauge showed around 14volts. After awhile I noticed it start to go down. By the time I pulled in my garage it was just a tick over 13v. My battery reads 12.4v when I test it with my Fluke meter. I have no idea how old the battery is (Duralast)... Do you think I'm having an issue with my battery or possibly my alternator? If so, what should I check?
Thanks

I dunno, seems normal for a fully charged battery to have the charging volts/amps drop off quickly... and 12.4 volts seems normal if the car is not running. ???
Is it different or something? Why do you think there is a problem?

Thanks guys... just wasn't sure if it was normal. I worry about stuff too much sometimes. From what I've read 12.4 volts means battery is at 75% so there should be some life left in her.
Thanks again.
