6 AWG, 4 AWG, 2 AWG or 1 AWG in Red or Black sold by the footChoose Size, Color and the QUANTITY IS THE LENGTH IN FEET (Ex: Qty 12 = 12 Foot)Our EXTREME battery cable is Made in the USA from pure OFC electrolytic copper in a fine stranded, type III rope stranding. You choose the wire size, color and length by the foot that you need...easy! Premium Real Oxygen Free Copper (OFC)FULL AWG Copper Gauge SizesVery Flexible StrandingDouble Insulated This extreme battery cable is specially designed to meet the demands of various environments while staying extremely flexible. Full AWG sized copper conductor made from 99.9% pure annealed electrolytic copper will deliver maximum power where you need it. The insulation and jacket compounds are specifically formulated to stay flexible, even in cold weather, and carry a -49C to 105C temperature rating. The jacket is resistant to chemicals, water, abrasions, oil, sunlight and has a color coded dual extrusion jacket with a white inner insulation which would show any damage to the outer cable more clearly. This cable is rated up to 600 Volts and is suitable for use in automotive applications, welding cables, solar battery bank wiring, power inverter battery cables, marine battery cables and many other applications calling for a durable yet flexible battery cable. The battery cables meet the requirements of SAE J1127 (Type SGT) and SAE J378 making them ABYC and US Coast Guard approved for boat and marine use. These cables are very suitable for use as welding cable and have up to 15% more copper per gauge size since these cables are FULL AWG Sizes copper content.

Many products on the market use CCA instead of real copper and most people just don't know the difference so here you go:Our copper cable is rated to 100% conductivity vs 61% for Copper Clad Aluminum (CCA) meaning you need 2 sizes larger for a CCA cable than you would if you used real copper. Copper is flexible and doesn't break easily but Copper Clad Aluminum (CCA) expands and contracts nearly 1/3 more than copper from heat. Add to that the fact that aluminum has around 37% of the tensile strength of copper and you have the potential for breaking strands and loosening connections...something you shouldn't mess with in high amperage DC Voltage applications!Copper Clad Aluminum was designed for AC voltage use especially in high frequencies like those found in signalling and telecommunications as AC current travels on the outside of the conductor so aluminum inside and copper outside meant an overall lighter weight and lower cost wire...but there is not a single benefit in DC voltage! It's a sad abuse by manufacturers to sell low quality cable dressed up as copper to unsuspecting buyers.So now you know why our REAL COPPER cables are superior! Share this info with family and friends and BE SAFE! Use REAL COPPER...like the soft annealed copper which makes up all of our durable and flexible multi-rated battery and welding cables.
