Ok, got up this morning and made a cup of coffee to enjoy with my morning vape. Grabbed the Lux, unlocked the ring, fired the button....nothing. Tried again....nothing. Scratched my head, unscrewed the atty, screwed back on and still nothing. I know it was a newly charged battery because I put it in a couple hours before I went to bed last night, but proceeded to check anyways. Unscrewed the bottom firing button and noticed some black looking ink substance on the bottom of the battery and on the center nut of the firing pin. I wiped it with a moist paper towel and it came right off.
Worried that I messed something up and possibly melted my battery or even worse...the Lux, I checked the battery with my multimeter and it is right around 4v. Put the same battery back in and now it fires away. Chained vape for a bit and the battery seems normal, not hot, no venting, or any negative signs of a bad battery. I will check again later to see if I get that black substance again, but in the meantime, I was hoping someone could chime in on this for me.
Is it possible that the gold plating was melting off from the bottom firing pin?
