A battery without pressure relief is definitionally a pressure vessel. How much damage it actually does when it explodes is another question entirely.

It's a very minimal amount of pressure it can withstand, is the point. Certainly nowhere close to lethal explosive pressure. It's not a pressure vessel in the sense of the kind of pressure vessel it takes to make an effective bomb.
