Car battery with stripped threads in female connection for bolt entry.

Use a lag bolt.

Good idea Hank: But not too deep a lag bolt cos it might break into
the interior of the battery. Or get a suitable diameter size lag bolt
but grind off the pointy end so as to make it less deep.
Another idea is to wrap some wire, copper or stainless steel, around
the bolt and see if that will secure it.
Also a similar but very slightly larger bolt might be used to cut new
and slightly deeper threads into the lead insert. e.g try a non metric
in a metric thread, or vice versa. Inspect the nuts and bolts junk
box.
Number of other ideas would include filling in the old threaded hole
with melted lead (from old balance weights one is always picking up
around tyre changing locations! Don't you? We do; might always come in
handy for something!!!!!) Then carefully drilling and tap threading
anew.
