Duracell batteries can't leak? Alkaline is non-corrosive (or none corrosive as you say)?
Man. I dunno what part of the universe you're living in but the last time I checked with physics laws, ANY alkaline or acid can cause corrosion. Alkaline environments are less prone to cause corrosion than acidic environments, but it is possible for alkalinity to cause corrosion as well. An alkaline environment is a setting that is strongly basic or contains alkali components. This usually refers to an environment with a pH value higher than 7.0, since a pH below 7.0 is considered acidic.
In alkaline environments, the number of hydrogen atoms are able to counterbalance acids. Therefore, when a solution is said to be alkaline, it is known as basic and has the formula to counter the effects of acids, which are a major contributory factor in corrosion.
Although alkaline environments are less dangerous, metal corrosion can still take place in alkaline environments, especially when there is existing dissolved oxygen. Water solutions can dissolve the oxygen present in the air quickly, which produces the oxygen necessary for the process of corrosion. One typical example is iron rusting when it is exposed to a damp atmosphere.
One typical example of metal that corrodes in an alkaline environment is zinc. This material is not usually used in either alkaline or acid solutions because it undergoes corrosion in both types of environments. Acids in minute amounts can hasten the corrosion rate far beyond the approved limits. On the other hand, although alkaline solutions are less corrosive to zinc in this case, the alkaline environment is still corrosive enough to damage any structure made from zinc.
Every alkaline battery has a liquid electrolyte that breaks down over time. Breakdown leads to the release of hydrogen gas. Over an alkaline battery's normal life, what we call 'off-gassing' isn't a problem. But if an alkaline battery sits too long, the pressure inside can eventually rupture the case.
Google is your friend.
And of course, I could be wrong. Note worthy also is the fact that Duracell isn't the only alkaline battery that leaks. ALL alkaline batteries have the potential to leak and corrode. Been happening to me since the first alkaline I bought. It's just that statistically SOME manufacturers are more prone to leak than others.
'Nuff said by this old man.
