well, i have never tried it, and im not a chemist and since its been a while since i took chemistry i couldnt remember all the info about the reactions. i just remember my high school chemistry teacher telling us about it in class. it sounded like a good theory when he told us about it.
true to an extent. i have worked as a service tech for fueling equipment for over ten years. older gas stations with steel underground tanks use a very similar method to keep these from rusting for many years. multiple large anodes are attached and impressed current(voltage) is applied to the system. the anodes take the corrosion. google cathodic protection. it works but the anodes are of a large size. not a penny.
the ground they sit in is also very moist and full of ions, and the tanks are full of fluid also. it not the same situation with a car. i have seen what you are talking about also though. when applied correctly, it works wonderfully.
Yeah.....I just take my battery out and set it down on the concrete next to the car whenever I'm not using it. That way my battery is preserved from corrosion and I always know where it's at whenever I want to put it back in. No pennies, no corrosion.......... Oh yeah......does anybody know where I can find a new battery?
