Re: 123\'s on airplanes?
Transporting small quantities of batteries shouldn't be a problem. Only take what you think you'll need for your trip.
As Xrunner said, secure them. I suggest binding them side by side with tape or rubberband, and putting them in a small bag. You don't want them to short out and cause a fire. I suggest you put them in carry-on. Same goes for all batteries.
