It seems to be solidly in the ceiling and I don't want to break it.
Yes it has a battery that needs to be replaced. You should be able to either twist it to the left (counter clock wise) or it may have one edge that pops off and will swing down to the side in order for you to get to the battery.
Note to everyone, change your batteries in the smoke detectors.
