All my batteries have a little circle on the positive post as if my pin burned a little circle into my battery. Why is it doing this? I'm running a FUHatten.

1. Could be copper oxidation from the positive pin.
2. FUHatten mods have a solid pin that doesn't move.
It could be a bit short, causing a slight arc, which could leave a black mark on the battery.
Actually it sounds like the wear ring you get from the battery spinning against the pos post during tightening.
if thats it dont tighten it too snug anymore
my valkyrie did something similar and I remember having to take all the contacts out, sand em down, and it solved the issue. rough castings on all the surfaces.
course, make sure you dont do this to plated contacts =P
In mechanical mods every time you hit the button to make contact with the battery a small spark is generated there. Each time this happens a very small divot is melted off of the contact surfaces.
I use a Reo Grand for most of my vaping. It has a door that can be taken off the mod and the mod can still be fired. When I do that and fire the atty I can see the spark.
All my batts have this circle of tiny divots on the positive end. It doesn't make any difference to performance. I do give them a slight rub with 1200 grit sandpaper every month or so, but I doubt that makes any difference to this issue
