I've accidently had the the battery cables hooked up wrong once, but I quickly removed them and redid it with no ill affects.

If you don't check them regularly, like once a year, the battery/alternator hookups could affect each other with one causing the other to go out sooner. I've had it happen several times. You can buy a simple battery/alternator check device, I think for less than $10 USD.

This is what I use to check both twice a year, but if you took it somewhere and it checked out on a machine, I would go with that over the verbal of a shop, unless you really know their reputation.

A battery consists of multiple cells. If the cells are damaged, the battery can short. –  hillsons Nov 3 '12 at 21:49
    
I wasn't thinking, of course it can short out. –  James Drinkard Dec 1 '12 at 22:39
