My laptop's li ion battery had a small blueish stain. I wiped it with toilet paper and put it away for now. The battery wasn't swollen and it didn't seem damaged. But I can't find any info on what this is and whether it poses some sort of health risk to me. Anyone know what it could be? Some sort of metal corrosion?
