As it turned out....
Wow, now I feel really foolish. I had tied a piece of string to the lens cap so I wouldn't lose it. The string is black, and I did not see it. Somehow, the string had broken from the lens cap, and it was in the battery well with the battery. I pulled on the string when I saw it, and it came out with difficulty, and so did the battery. Turns out the spring on the floor was not the battery spring, and all is well.
So it was the string that made the battery stuck in the camera and not the battery swelled?
