I have opened an ordinary battery to get the carbon rod and the black powdery stuff around it stained my drawer. I had some nicads in there and I was wondering if the nicads would be affected?
Some of the batteries did have some white stuff on the positive terminals, but this could be down to old age or misuse.
Should I be concerned?
I assume you mean it stained your desk drawer, and not your intimate apparel. :)
I probably tore open a hundred batteries as a kid for carbon rods, and haven't suffered any ill effects so far. Some of the things I did with those rods were a lot more hazardous though. Anyone remember the "build your own arc lamp" project from the 70s?

Yeah, some of the nicads in the drawer had some white stuff on the positive caps, I just hope that the nicads leaked because they were OLD and not because of the slight manganese dioxide that might have been in contact with them.
