Unfortunately, this sort of thing (and most things these days really)
are considered non-serviceable assemblies and parts are not available
individually. Gorilla glue is not the best choice for this, it tends to
foam and expand significantly as it cures. A better bet would be epoxy,
you can get it specifically designed to bond to plastics, I think the
stuff I have is called Plastic Weld. It bonds very well to most plastics
and is sturdy enough that I've used it to mold replacements for missing
sections of parts. Cyanoacrylate (superglue, crazy glue, etc) will
usually work too, but it tends to get all over everything and the vapors
turn finger oils into whitish deposits. Glued very carefully, you should
be able to crack it back open later to change the battery.
