Sanyo ( japanese manufactured) is just fine! Superfire is NOT!
Apparently Superfire batteries are manufactured by Starnova in Shenzhen! No quality control!
Wow, this is no good.
I think my Arctic came with a Sanyo battery.
I would be concerned about the air quality in the room after a cell exploding like that. I would not want to breat the air in that room after the battery has expelled all it's toxins in the air.
