    Default battery vs concrete

    Many years ago, I was told to never place a storage battery on a concrete floor because it will drain the battery.
    Has anyone else been told this? Is it true? It never made much sense to me that it would do this, but I've always refrained from doing it just in case it's true. Anyone have any thoughts on this?

    I think that came from yrs. ago, before batt. cases were made out of plastic. It doesn't affect today's batt's but I still set them on something other than concrete if possible.

    Batteries used to be encased in pitch-soaked wood or rubber. Even at that, I can think of no good reason why that particular myth ever started.
    Suffice to say, it's a load of old tosh, and can be disregarded.

    <edit to add>
    It might have been more to do with leakage and the effect on the concrete. Garages tended to have particular areas where batteries were tended to, and setting down batteries on the floor day after day would have led to some corrosion issues.

    Both replies (so far) are hinting about problems with OLDER batteries. REALLY old, as in 40-50 years ago. Battery cases used to be made of rubber. Treated to be rigid and somewhat non-permeable, but the calcium in the concrete could leach through the pores of the rubber case and neutralize the acid. Even a piece of paper would stop that, but most used a block of wood or similar.

    Today's batteries have plastic cases and the leaching is NOT a problem. Put your battery anwhere you want. However, if you have a standard "wet-cell" battery and are charging it off the bike, ... if it overflows, you might want to have something other than concrete under it. The acid will not do good things to the floor. It's better to have some cardboard or a piece of wood to absorb the fluid.

    I never store batteries on the floor. I just don't.

    ...not for any tangible reason except maybe having them a bit higher saves lifting them that much more, but unreasonably, it just seems wrong. Maybe the temperature differential twixt "ground" and surroundong air but whatever...pallet height is minimum in my world.

    Carpet, wood floor, then concrete - right here on the living room floor!

    Many, many years ago, I was taught that a battery set on a concrete floor was "neglected" by definition. A "neglected" battery will discharge over time. .02

    Interesting. My father always followed the not on concrete storage.

    When consulting the magic 8 ball for advice, one must first ask it "will your answers be accurate?"

    So did my dad, and he was a career Porsche mechanic. I think it was a carryover from his early days with British Leyland.

    It seems to be decided that this is old and outdated advice. I was told about this myself 40-45 years ago. Obviously, to make up for lost time, I should go out and remove all my batteries and set them on the (concrete) floor. .............mmmmmaybe not.
