■ Overview A long-selling product that has been sold on Rakuten Ichiba for 10 years. Easy installation, just replace the existing battery ground cable that connects from the battery's negative terminal to the body ground. It's flexible, making it easy to handle. All conductors are high-purity oxygen-free copper with low electrical resistance. We will manufacture it to your specified length in 1cm increments. ■ Terminal Shapes: 3 Patterns A) M6 round terminal - M6 round terminal B) M6 round terminal - M8 round terminal C) M8 round terminal - M8 round terminal ■ Price 9cm～29cm: ¥3,200 30cm～39cm: ¥3,500 40cm～49cm: ¥4,500 50cm～59cm: ¥5,000 60cm～69cm: ¥5,500 70cm～79cm: ¥6,000 ■ When Ordering Please let us know the length and terminal pattern.

Please order with a little extra length. Electrical resistance is proportional to length. If you make it unnecessarily long, the effect will be diminished, so please choose a length that is sufficient. Thicker and shorter is the rule. If your car has a current sensor installed on the battery's negative terminal, connect it to the current sensor instead of the negative terminal. Please clean the vehicle-side connection points by removing dirt, rust, and paint before connecting. Applying conductive paste such as Copaslip to the terminal contact points is even more effective.
