After some thought, I came up with a quick way to test the battery. Just open Photo Booth and point your remote at the camera (make sure the end of the remote is visible in the onscreen image), then press any button on the remote (volume up or down, for instance). If you see a bright light emitting from the remote in the Photo Booth window, you know the remote's working OK and has battery juice.
[robg adds: I tried this with my MacBook Pro, and it indeed works quite well -- the infrared light is picked up by the camera, and shows up very brightly in the Photo Booth window. Obviously, you could use any app that lets you see the camera's input in real time, not just Photo Booth.]
