* Note: Due to the nature of the sulfuric acid commonly contained in marine, RV, and automotive batteries, we strongly recommend using 100% polypropylene materials when used as a battery tie-down (especially without a battery box).  We also strongly recommend the use of battery boxes (available at many retailers) in conjunction with Load Lock® Battery Tie-Down Straps.
