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

It's nearly new and cost a small fortune; is there any way to save this
battery?

Checked at Lowes, Canadian Tire and NAPA; the only advice anyone had was
to put a larger bolt on and "force" it to thread into the lead. That
doesn't sound very reasonable to me.

For the time being I've slipped some solder around the threads to take
up space and it let the bolt tighten into the battery firmly, but since
solder has no "memory" (will squash and not apply any pressure
eventually) I don't think it's a very reliable "fix".

Any better suggestions?

Any old time roofing supply or gutter installers near you? Some skinny
strips of lead sheet, beaten thin, hung in the hole before you insert
the bolt, may work. Like putting a toothpick in a wallowed-out screw
hole in wood. Probably want a bolt with a taper on the end. The strips
and the hole need to be shiny when you do this, of course.
