Charging Car Battery On Concrete Floor

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.

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. If a battery is clean you can safely put it on your concrete floor. Even an acid spattered battery will not leak its charge into the earth. Apparently he is under the impression that putting a car battery on a concrete floor would drain it.

If it s acid spattered put it on somebody else s concrete floor or stick a board under it. A reader asked us to look into this myth because he was concerned about battery life in parking meters. Naturally if a topic or concept is not very well understood people can fall prey to all sorts of rumors and myths that spread from generation to generation and the question of a car battery draining on a concrete floor is one of them. Encased in steel an edison cell battery placed directly on a concrete floor would discharge more quickly than normal.

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. There may be leakage across the terminals of a top post battery but that would be slight.
