When I placed an automobile battery on a concrete floor, Someone said to get it off the floor because it will discharge the battery.

Never leave batteries on the ground or a concrete floor...all the power will leak out."
This one is a "rural legend"--batteries don't care what they sit on. It probably originated from when batteries came in porous wooden cases. There are some truths behind this myth, though! All batteries do self-discharge over time when they are not being charged. If dust and dirt build up on the battery tops, sulfuric acid will carbonize the grime into an electrical conductor, acting like a short circuit across the terminals and quickly draining the power. Cold temperatures also reduce available power from a battery. And thermal gradients can reduce the life of large battery...this can occur when the air temperature around a battery is much warmer than the surface it is sitting on.

No need to worry, a concrete floor will do nothing to your battery as the casing is an insulator. Of course a battery will lose its charge if left unused no matter where it is stored but this is quite a slow process.
