I was noticing the spring didn't seem to be applying much pressure to the battery in my Provari. So I pulled it out and stretched it out a bit and cleaned up the threads on the cap. Everything was working just fine before I did this. Afterwards, I was vaping away, and I realized since I was very sick I hadn't vaped much the past few days, that I was on the 2nd day of this battery. So I checked the voltage, it said 3.4, and no blinking LED. Usually, as other have noticed, it blinks much sooner. More like 3.6, 3.7 volts. The way I have it now the spring touches the battery just before the threads on the cap do. Has anyone else tried this? Any thoughts?
