Do Concrete Floors Drain Batteries

Battery myth 2 storing a battery on a concrete floor will discharge the battery.

Do concrete floors drain batteries. Batterystuff knowledge base article answering the popular question about battery storage. And because of the porosity of that material battery acid would sometimes seep through. Not only that but that the battery would not take a charge after this occurred. And the potential problem of damage to the concrete floor from battery acid leakage has also been mostly mitigated as previously noted by interstate batteries.

Nowadays containers are made from a solid plastic that does not allow any current to flow through it so the batteries do not discharge even if they sit in a few inches of water interestingly enough many experts such as car talk s click and clack think that storing car batteries on concrete floors might actually be a great idea. 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. In the past yes batteries stored on concrete floor would loose charge because of the free electrons grounding themselves outside of the battery. There is not currently a strong reason for avoiding contact of a battery with a concrete floor.

But the real concern was the batteries. Thirty years ago or so most battery casings were made of hard rubber. If these batteries do discharge faster than expected i suspect it has nothing to do with the material upon which they sit but with the ambient. 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.

Today all of these automobile battery destroying or current conducting flaws have been eliminated by using plastic shells around the various types of battery designs. 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. Modern batteries are fully insulated and do not experience this problem anymore.
