I have an eGo and while changing Atty's this morning I noticed that there was some wetness on the center post of the battery. Since I drip, I thought, Ok too much juice once. So I got a q-tip and cleaned the inside.
While doing this, I noticed that I got some black "stuff" off of the threads. I cleaned all this stuff off and put it all back together and actually got better vaper. I think this is because the "black stuff" was creating a resistance on the negative side thus the battery was not putting out the same voltage to the atty as it should.
Has anyone else noticed this? Is it just tarnish from the brass? Wha'ts up dudes and dudettes!?
