When I charged my batteries for the first time, I noticed some dark staining around the ends on a couple of them. Not much but still there.

When a neighbouring team came to meet with us, I noticed even bigger stains on their battery after it's first charge.

You can see the stains because there is that red paper on the battery ends.

This doesn't seem normal or safe. Anyoone else see these marks.

Should we only be using the "low" setting on the charger?
Technical details are pretty sparce on these new sets.
