1. Sturdy and Safe Battery Cables Tinned copper wires have good electrical conductivity, thermal conductivity, and stability. Tinned copper can increase heat dissipation, improve electrical conductivity, and enhance performance to some extent. Its maximum temperature can reach 100 degrees Celsius, reducing the risk caused by excessive temperature and ensuring safety. 2. PVC Insulation Jacket This 12V automotive replacement battery cable uses flexible PVC insulation material, which has characteristics like wear resistance, water resistance, and moisture resistance. At the same time, it has flame - retardant and heat - insulating functions and can withstand the tests of automotive or marine environments. The ring terminals at both ends of the cable allow for easier connection to the battery terminals. 3. Tinned Copper Terminals This 16mm automotive battery cable is made of tinned copper material, which has good stability, wear resistance, and corrosion resistance. It improves the oxidation resistance of copper and helps maintain its electrical conductivity. The pure copper wire is paired with nickel - plated copper terminals, which can achieve relatively high power transmission and provide anti - corrosion protection. 4. Two Different Colors You will get two battery cables with a length of 50cm or 100cm, which are red and black respectively. Red represents the positive pole, and black represents the negative pole. The maximum charging rate is 100A (12V). The different colors are easy to distinguish, making the use safer and suitable for parallel or series connection of batteries. 5. Wide Range of Application Fields The flexible copper wires of this 5AWG automotive battery cable can effectively improve automotive performance and bring a better driving experience. Battery inverter cables are commonly used in power application scenarios such as automobiles, trucks, ships, solar power generation, RVs, trailers, golf carts, motorcycles, and lawn mowers.
