Checked the battery when I got home. It was 3.4 volts. Don't know if it fired constantly for 25 minutes or was intermittently firing during that time.
When I pulled the top off, I tossed it on the floor of the truck. Without the nut, the button and spring decided to hide in another location. Burned my fingers in the process. I have the set screw in place, so getting the battery out took some doing. Definitely my scariest vaping moment to date.
Just still wound up. Check your nuts everyone. I've touched mine several times since. My wife is not amused.
ouch! I'm truly upset that this happened. We haven't PMed, and I won't plague you. But I'm here and I'm all ears.
