Batteries removed from the module, are they still useful?

How could anyone possibly know that answer from only a single photograph?

Do they have a date code? Do they have any charge on them or are they flat?

The battery still works, I've tried spot welding and tinning. I am trying to figure out what I can do to get him working again.
