[QUOTE="AtomRat, post: 310095, member: 3111"] Just for the hell of it I ripped open a super heavy duty AA batt. Set of pliers, no probs! There was a different small amount of black goop on the top of mine, not exactly sure what it was, but all it contained was the carbon rod, manganese dioxide and end caps. To test if the case is zinc, (not aluminium) you can either put a drop of copper sulfate solution onto it and see if it turns white, or if you scrape up a thin slither of it with a sharp tool it will burn into a smoke where alloy will get hot and stay. Cant find my copper sulfate so will do that in morn. Burn test is a bit difficult to determine [img]https://scontent-syd2-1.xx.fbcdn.net/v/t31.0-8/cp0/e15/q65/s720x720/16707398_10154404430476279_1945146122084009062_o.jpg?efg=eyJpIjoidCJ9&oh=66b64d333b928a43a0bfd77c1a4e1857&oe=594A081E[/img] [/QUOTE]
