Copper battery terminals offer the highest degree of electrical conductivity

Copper battery terminals offer the highest degree of electrical conductivity, provide a high degree of strength, and can be easily soldered or crimped using the proper tools. Constructed from die-cast copper and tin plated,  copper battery terminals will fit cable sizes ranging from 6 gauge to 4/0 gauge battery cable. These terminals come in four different configurations: Straight barrel, right angle, left angle, and parallel, which are used to connect multi-batteries together in battery bank systems. Battery terminals come in either positive or negative polarity for use with either the positive post or negative post of your battery. Smaller gauge terminals are universal and the same terminal can be used with either the'+' or '-' side of your battery. Each terminal is marked with it's polarity as well as it's gauge size. Includes 5/16" bolt and nut. Copper battery terminals are an excellent choice for reliable higher current electrical systems.Copper battery terminal.The high thermal conductivity of copper is also second only to silver, such as refrigerators. , evaporators, heating coils, etc. all use its thermal conductivity; another important property is corrosion resistance. 
The positive and negative poles of the car battery cable, the connector with the heavy-duty copper ring terminal classification kit.Seamless copper lug made of 99.9% pure conductive ETP copper. Copper lugs are clearly marked for wire size. Features a flared and chamfered barrel to ease application of finely stranded wire or welding cable. UL Listed and CSA certified.Straight barrel copper die cast battery terminals can be crimped or soldered. Includes 1/2 inch bolt and nut. The ‘X’ in the part number denotes cable size. Available in 6 gauge, 4 gauge, 2-1 gauge, 1/O gauge, 2/O gauge, 3/O gauge, and 4/0 gauge. Sizes larger than 4 gauges are polarized. 6 and 4 gauge sizes work for both positive and negative connections.Copper battery terminals have high conductivity and can be used in cars, motorcycles, and recreation vehicles.Copper has excellent conductivity. In terms of unit volume, the conductivity of copper is second only to silver.
It is used as wires and electrical parts of electronic and telecommunication equipment. Battery terminals are heavy duty copper battery cable connectors with tin plating to resist corrosion. Each tinned copper battery terminal is color coded with the crimp die and crimp position(s). The tinned copper will not turn black or green like non-plated battery clamps and can be crimped or soldered. Ideal for battery terminal connections in marine and automotive SAE stud battery posts, these lugs are sized to properly fit flexible stranded copper battery cable and other type of flexible wire gauge (AWG) sizes. Available in straight top post, elbow terminal and flag terminal configurations. These cable connectors can be crimped or soldered.
