The rubber was porous and often contained carbon

That's enough right there; rubber with carbon in it can conduct electricity (see also, "why do cars get hit by lightning when they're riding on rubber?" - note that some modern tires actually have too little carbon in them for conductivity so have an "antenna strip" to help this) and so there can be leakage.

Don稚 leave a car battery directly on a concrete floor.

Every time I have done it the battery cracked and leaked.

I am pretty sure you should not drop them from a 4 foot elevation to the floor.......

Another one:

It is safer to pull hard with a chain than a strap or cable, because if it breaks, it will fall harmlessly to the ground instead of snapping back.

It is safest to pull hard with something that doesn't stretch. When something stretches it is storing energy like a spring and if it breaks that energy will release as a whip.

And what do you propose that the average mortal with a less-than-10-figure bank account can afford?

A chain is good. Steel cable.

The more you argue a point, the more likely it will be to convince everyone else.

You just can't give up, can you? According to my link/quote they both caused problems. Also, even a modern battery will leach if there's enough dirt and grime on it, and the moist environment which many concrete floors provide will enhance that.

So adding a piece of plywood or some other thin spacer cleans the dirt off and prevents moisture? I’ll have to remember that one.
