Our marine battery cable is Made in the USA from pure 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!

Each strand of copper is electro tin plated which keeps the copper from corroding. Tinned copper is preferred for long life of the copper conductor and is great in the marine environment as well as automotive! 

***IMPORTANT!!! Don't get suckered into buying copper plated aluminum (known as CCA copper clad aluminum) as our REAL COPPER CABLE will HANDLE MORE POWER!!!***

The marine battery cable insulation is flexible and durable designed to withstand water, salt, gas and oil unlike more commonly available welding cable.
