Hello to All,
I always thought that sitting batteries on a concrete garage floor would suck out the charge. If it were true, wouldn’t direct contact with the ground do the same?…but is the concrete myth even true?
I’ll take this one on.
No, it’s not true at all. Through the automotive ages, when a guy works on his car (in the garage) and he has to remove the battery, does he pick up the heavy thing, lift it high and put it on a flimsy shelf where it can break the shelf or fall off of it? Or, does he do the normal common sense thing of hefting it out of the car and lowering it onto the floor? Of course, he puts it on the floor, which in most garages, is made of concrete. The only thing that ‘sucks’ the power out of the battery, is the act of leaving it out of the car for many months at time uncharged to slowly sulfate itself to death. It would do the same thing if it were sitting in the living room on a coffee table along with Harper’s Bazaar. In fact, the concrete floor ‘may’ actually help keep the battery alive longer than a shelf or the coffee table would, because it is usually ground temperature and thus, cooler, which is better for storing a battery for a long period of time.
I hear this old myth 100s of times a year, I swear. Maybe we should send this in to Myth Busters?
