Charging Car Battery On Concrete Floor

So here s the story.

Charging car battery on concrete floor. If a battery is clean you can safely put it on your concrete floor. There may be leakage across the terminals of a top post battery but that would be slight. Even an acid spattered battery will not leak its charge into the earth. If it s acid spattered put it on somebody else s concrete floor or stick a board under it.

Not only that but that the battery would not take a charge after this occurred. Cement and concrete floors provide a fairly good barrier between the car battery and extreme temperature changes that could otherwise cause damage to the battery cells. Advancements in battery technology ultimately led to a nickel iron battery known as the edison cell which was more durable but also had a downside in its classic form. The design of modern day batteries includes a hard plastic shell that eliminates the intake of moisture thus making the garage floor a great place to put your car battery.

A reader asked us to look into this myth because he was concerned about battery life in parking meters. Before we dwell into the details the myth has some historical basis. These meters all use a 12v battery to either deliver main power or serve as a backup and these batteries sit on a sheet of steel set atop concrete or sometimes directly on the concrete itself.
