FWIW, I have a friend who worked at a photo developing shop. They took in a ton of disposable cameras, and developed the film for customers. At the same time, they also scrapped out and salvaged the batteries inside the cameras.
One afternoon, they had several cameras laying on the counter that had been busted open, but the film was already developed. I picked one up, and opened it. Just as my friend said, "Be careful, there is a capacitor in there that can get you", I accidentally touched it.
It was a bad enough shock that I still vividly remember it...it isn't something you forget caused by a capacitor energized by two AA batteries.

You always have to be careful when dealing with electronics or electricity..
If you don't you will end up hurt or worse, dead! So scrapping isn't for everyone (thankfully), other wise those of us that do scrap metals wouldn't make what little we make..
For example the aluminum market tends not to fluctuate as much as other metals. The reason is there is a steady supply from curb side recycle bins...
You also have to watch out for the chemicals and oils in certain coils etc.. Some of it may be toxic.. So use common sense, wear protective gloves and safety glasses etc...
