What makes a battery corrode?
This device has been inside its whole life with occasional use. It consists of an LED, a resistor, three AA's in RatShack holders, and a push button. For the second time one of them has corroded and split open; IIRC it was in the same slot. Is the holder crappy? Am I buying punk batteries? Circuit issues (this was my first soldering project)? Basically, does my circuit need trouble-shooting or is it just dumb bad luck? Thanks!
