Ever heard of the penny trick?

sorry but thats not the case. first, the copper is an electron donor. second, all thats happening is that if you get moist air or water to allow electron flow (electrolyte), the copper steals the electrons from your battery in order to react with oxygen in the air, creating copper(II)oxide. i'm sure this 'trick' showed the copper being oxidized, but that doesn't mean your car isn't being oxidized at the same time. it may work locally, such as for terminals, but don't expect much (if any) result on the rest of the car except maybe a shorter battery life

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.

I just take the battery out when i'm not using it for a while.

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?
