Btw there are no shortage of videos on youtube of these batteries blowing up. If you weren't in the room at the time to throw it out, as it was swelling up, you'd be screwed. They really make quite a big fire from such a small battery.

Watch a couple, most are in controlled circumstances, so there pretty fun to watch. Just because it's "controlled" (outside and far from people) does not mean it won't be as bad of an explosion in your case.
