Can I Store My Battery on a Concrete Floor?

This one is an often heard ‘old wives tale’. It used to be that battery cases were made of inferior material such as hard rubber, or even tar. This material would develop micro cracks over time and become porous, and left on wet ground or damp concrete would begin to self discharge. Nowadays, battery cases are made of plastic that do not leak and can be stored on nearly any surface, even left in standing water with no ill effects.
