FiOS box battery replacement

[fogged]

How do you open the FiOS box-on-the-wall to take out/replace the battery?

Is this explained -- is there a user-manual -- somewhere?

This link above should help. If you don’t have phone service the BBU is not needed.

on new installs there is a Power Reserve Unit (d cell batteries in a black case) that can be switched on and off. It might be on. Just switch it off.
