I understand that plating is a DC process. I have also seen (especailly on boats) where you get AC leakage and all the fittings will dissolve. I don't like the idea of having the car continuosly connected up to the house AC power. I have seen electralisys (oops) on cars and the best guess was the trickle (float) charge that the owner says he used. Old anit-freeze will only contribute to the problem. There can be a HUGE difference between a battery charger and an alternator. Alternators do not have much filtering so they send out a large ripple that the battery absorbs. Some battery chargers do much worse and if the battery is bad then there is nothing to absorb the ripple. The AC will float around with small leakage currents capable of causing electrolysys (oops again). The one thing we both agree on is that cars were made to be driven. With all the different types of metals used in the car any electrolysys is dangerous. Especially over a prolonged period of time. If you HAVE to use a charger continuosly at least remove the battery from the car.

I agree that a trickle charger left on all the time is not a good idea because of the possibility of overcharging. A float charger may work depending if it is indeed a float charger. A battery will lose a charge very slowly because of its internal resistance that constantly causes current to be drained. I respectfully disagree with the antifreeze electrolyte hypothesis.
