Don't forget - they are glued in there too...
Pick which you want to destroy - the dead atty or the dead battery - use that end to pull on after screwing together..
So, if you want the battery end, screw an atty into it, heat in hot water or with a hair dryer, or heat gun, (but I assume that we are going as low tech as possible?) Cover anything you want to keep pretty with tape or something to prevent marring and start to wiggle on the atty with pliers or what have you...
Eventually it'll come loose....
All in all; I find it easier to just order new ones!
