Well i was completely wrong about using unprotected batteries. The 5 Volt Detonator did nothing to stop what happened. The vent holes may have helped to minimize the explosion but they did not stop it. It was pretty bad, I come to the forum tonight humbled and regretfull I ever used unprotected batteries.
OK so I had just gott some new Bright Blue CR2 batteries from Ebay. They were only a week old. They blew up and burned my leg, and scared the hell out of me. I had the Detonator in my pocket and I must have forgotten to turn it off or maybe it was off, I'm not sure.
Anyway " Boom" was the sound it made. I didn't have a chance to do any thing. The vent holes - did nothing. I do not recomend using Un Protected batteries at all. This could have been much worse if I was driving or holding it up to my face. I have heard of some protected CR2's but I do not know if they will run the 510 atty that is in my Detonator. I know some protected CR2's are out there and some are being developed / tested. If anyone has more info about Protected CR2's please post it up here.
I want everyone to be aware of what happen to me. Be carefull and stop using unprotected CR2's immediatly. This was much worse than I thought it would be. The explosion went through my pants pocket , boxers and into my leg. The JB weld nose cone held up fine.
