and to think many years ago they all thought the earth was flat, the earth was the centre of the universe,people were burned at the stake as they were thought to be witches, woman can not vote they were proven wrong. And in a couple of hundred years some one will prove that batteries on concrete was also a furphy.
May be it was brought upon by people constantly stubbing their toes on batteries placed on concrete, so the foreman said, all batteries must in future be off the ground and then some bright spark put a seed in to the mind of other that it was due to discharging

If you use a high current charger then keeping the batteries up off any floor, not just concrete, so that the batteries can get some form of air flow around them, is not a bad idea but, high current charging in itself IS a bad operating practice in the first place.

High current charging will cause the battery to warm up and having the battery in direct contact with any form of floor will slow heat radiating away from the battery, which in turn makes the high current charging just that bit harder on the battery.

All my batteries have always been housed on the floor of my workshops/garages but, other than during experiments and tests, under normal use, I have never had a need to fast charge batteries so over heating is not a problem.

So if you use a small current charger, again, there is no reason to remove batteries from a concrete floor.
