You should always take expensive equipment, like cameras, in your hand luggage. If you have only the one battery it should sit in the camera. It is only when you have spare batteries that you might run into problems. But having traveled with one or even two spare batteries for my Canon super compact camera as well as a spare battery for my phone, I have never had inquiries about them when passing security.
I keep the spare batteries with an official battery cover in a pocket of the camera bag. That is according to the rules as I read the TSA website. For the phone battery I never had a cover but I have it wrapped in a plastic bag in a fitting box and it sits in my handbag. Maybe not 100% to the rules but clearly out of harms way and as it is just the one small item, the security guards do not seem to worry about it.
Here you find the official TSA rules. German Airports as all EU airports, for your return journey, do keep rules very much alike, if not always completely the same: http://www.tsa.gov/traveler-information/safe-travel-batteries-and-devices

I just wanted to give some short feedback on what I have done:
Upon TSA security check I put those bags and camera into the containers.
Everything was fine - no one bothered and seemed totally legit.
