There are probably better wireless water leak detectors out there. To answer your question, the Raspberry Pi isn't battery powered but I suppose it could be. They run off USB power, i.e., 5VDC at various amperages depending on the model. The one I'm using for this application needs 2 amps. I run it off an extra cell phone charger I had laying around. So, I assume one could probably use one of those mobile phone charging backup batteries that are on the market to make it battery powered. Not sure what the run time would be on one of those however.
