It's a little hard to make out from that pic...but since you say it's a burn mark, it means "throw me out and get a new one before I fail completely and short out 'cuz I'm just a battery at the end of it's life."

Well, there isn't much else to say about the bat is there.
I guess you could always put it on a charger to see if it will burn the house down.
If you would like a description of what happened to the bat, it carbon tracked to ground.

This battery is only three months old. I've barely used it since I got my LiFEPO4's two and half months ago. The burn only appears to be on the sheath and not down to the battery metal itself. I looked inside the silver bullet and there doesn't appear to be anything that could do this. I wonder if maybe the charger itself made this mark or if it is actually the battery.

Oh well, I guess it's not worth the risk. I have my two other 18650's, two sets of LiFEPO4's and sitting in my mailbox right now are two 4.8v NiMH batts.
Ya I knew, and your right, it just isn't worth the risk.
Roxics, the most common cause of that is a little moisture, and the electricity simple finds the path of least resistance.
Real common problem in automotive ignition systems.
What time is it when an elephant sits on your fence?
I can't believe I've never heard that phrase before.
Nope, time to get your shotgun and find the person that let the elephant out... (lol)
