Not a bad idea. I'm actually thinking my wife's hot glue gun would be useful for securing the battery in its holder.
The prong broke cleanly, not even a "stub" per say....so not much to solder. I think a quick drop of solder on the battery top won't be enough to heat the battery too much.
Yeah, it's a dumb thing to do. Amazing how that prong is such a weak link!
Thanks
