Using a tiny trickle charger, I charged a new battery on gravel last summer and managed to evaporate all the water away! Concrete (and maybe gravel) may act as an inductor that draws the charge from the battery through the case. As above, a wooden rack with a monthly trickle-charge seems like the better solution—but personally, I'd opt for twice-monthly.

I've heard it too, but I think what is heard is the added loading at the alternator belt.
