Know of a rumor you want investigated? Press related inquiry? Apparently, he is under the impression that putting a car battery on a concrete floor would drain it! Not only that, but that the battery would not take a charge after this occurred

Origins: Much of what makes a car go remains an arcane mystery to the average person. Automobiles are large and complex, and as any car owner quickly discovers, malfunction of even the smallest and most seemingly unimportant automotive part can be all that it takes to render them inoperative.

Tidbits of whispered wisdom therefore prove popular among the less than automotively inclined, who look to keep their vehicles running even if theyre not quite sure exactly how to go about that.

One bit of whispered wisdom dictates that a cars battery must never be stored on a concrete or cement floor. The reasons given for this prohibition vary depending on whom one hears the admonition from. Acid leaking from the battery will ruin the floor, say some. Or a battery left sitting on such surface will never again properly hold a charge. Or those particular surfaces will cause a battery to lose some of its charge.

handed down through three generations: just as there was once something to Grandmas oddball cooking secret, so too was there a time when storing car batteries on concrete or cement floors was a lousy thing to do. However (and again just like the cooking secret legend), whereas at one time there was good reason for the practice, those days have long since passed.

Car batteries used to be encased in hard rubber, a substance that was porous enough that battery acid could seep through it and create a conductive path through the damp concrete, draining the battery. The cases of todays batteries, however, are made of sturdier stuff that far better contains their contents than those of yesteryear. As well, time has brought technological improvements to the seals around the posts and the vent systems.

Interestingly, some experts (including Car Talks Click and Clack) believe that storing car batteries on concrete floors might actually be a better idea than keeping them on shelves or other surfaces because the cold of the floor works to slow the self-discharge (leakage) rate.
