I have heard that if you sit a battery on the ground or concrete that it

Here is a theory. If the floor is colder the ambient air, the battery may
develop a thermal gradient. Since lead acid batteries have a temperature
coefficient that will set up a vertical voltage gradient within the cell.
That voltage gradient will cause a current to flow within the cell leading to
discharge.
