Batteries used to drain faster if left sitting on concrete because concrete absorbs moisture, and the materials used to insulate the battery were not impervious to moisture. Hence a path was available to drain the charge from the battery into the moisture in the concrete if the battery was left in contact with it.
A very long time ago, before plastics, car batteries were actually housed in wooden boxes inside a glass cover. Wood readily absorbs moisture from any source, even air. Moisture would cause the wooden box to swell & break the glass enclosure.
Later, car battery housing was made of hard rubber with a high carbon content - also not impervious to moisture or electricity.
Today's car batteries are encased in highly insulative thick plastic cases. Unless your car battery is an antiquity that belongs in a museum, it is safe to store for an extended time it sitting on concrete. It should not drain any more of its charge on concrete than if it were somehow levitating in mid-air.
All car batteries will slowly drain no matter what you do. They drain more rapidly in hot weather & when high humidity is present in the air. If you happen to have retained them, I recommend that you store your battery with the terminal protectors in place on the posts on the top of the battery or inserted in the side receptacle terminals if it is a side-connect type of battery. Those plastic protectors that come on the battery from the manufacturer usually end up in the trash, but they are quite useful for minimizing drain if you need to store your battery for an extended period of time. It is likely that you might be able to get terminal protectors (post covers & / or side terminal inserts) from an auto parts store which also installs batteries on a regular basis - maybe for free.
Hope this helps!
