The two copper lug terminals on either end of the cable are machine-crimped and bonded with an adhesive-lined polyolefin heat-shrink wrap to ensure that the connection is electrically sound and physically durable.
These heavy-duty battery cables are built to withstand the harsh conditions of marine/boating power-supplying applications.. The tinned copper lead wire lends to a high corrosion resistance, and the PVC insulation protects the wire against abrasion, chemicals, oils, and solvents.Marine Battery Cable Set, 2 AWG Gauge, Tinned Copper w/ Black & Red PVC, 18" Length, 5/16" Lugs However, their versatility makes them ideal in a variety of other uses, including for power inverters, amplifiers/stereos, and automotive (car/truck/RV) batteries, as well as any other electrical applications requiring these specifications.
