I got an email from a friend the other day with some interesting information. She had watched Inside Edition and they did a feature on 9 volt batteries causing fires. Apparently when the batteries are out of there original package and just laying in a drawer or wherever, if the positive and negative terminals on those batteries come in contact with any metal, they can spark a fire.

Guess will be watching how I store my 9 volt batteries from now on. But I usually always keep them in their package. Interestng.
