The most of fire accident reason from dry cell still have not verified yet correctly. So some case of fire reason have been suspected of dry cell. Therefore this study want to define that the 9V dry cell can be able to ignite by short-circuit with circumstanced any conductor. Consequently through this reproduced experimental study, the appropriated conductor of ball point pen's spring will be prove that 9V dry cell has enough potential hazard to make occurring fire.
