The Cold Heat soldering iron relies on short-circuiting AA batteries across the soldered elements. With the steps you propose you might be on the way to force yourself to invest in (a) new batteries, (b) new charger and (c) maybe even new home, if you leave badly damaged batteries in a dumb fast charger.
Seriously, DO NOT try it. Buy extra batteries. After a while, another one will die.
