The final answer to the car battery on a concrete floor (ruins the floor)

  1. Oct 13, 2015 #1
    People keep asking about setting a car battery on a concrete floor somehow ruining the battery.

    Here is the final answer on the subject.

    I have the 1930s Popular Science with the original tip in it (but don't ask me which issue). The auto tip was:

    "Leaving a car battery on a concrete floor will ruin it."

    I have seen three concrete floors ruined by leaving car batteries on them. Acid vapors ate away at the concrete.

    That "it" in the auto tip has too many antecedents.

    :nb) Oh my, I better get the half dozen I have sitting in my shop, and take them to the recycle facility.
