Thats funny. Ever wrapped steel wool around both ends of a D cell? Great way to start a camp fire in a pich.

I put about 2 dozen SureFire CR123 lithuim batteries in a titanum coffee cup on my work bench one day. Started smoking really bad after a couple minutes.
Didn't know what it was a first, smelled like a burned up electric motor.

Glad it was sitting there and didn't walk away <img src="/forums/images/graemlins/scared.gif" alt="" />.
Pretty sure they would have caught fire soon if I didn't dump them out on the bench.
Should've known, it was bone head thing to do and could have got by butt fired.
