Universal Sizes: Suitable for wires with a diameter of 5.2–7.4 mm (AWG size 1–4) or a cross-section of 16–35 mm. Minimum cable size: 16 mm (5/8\"). Maximum clamp: 9.5 mm/0.37 inches. Mini clamp: 6.5 mm/0.25 inches. Robust and Durable: The quick-release pure copper battery terminals not only have good conductivity and corrosion resistance but also reduce voltage distortion and transmission loss, working 3 times faster than other superior terminals. Easy to Use: The battery terminal connectors are easy to identify with positive (red) and negative (black) labels. Comes with 1 hex wrench and two anti-corrosion washers for easy installation. Wires are easy to change, and the connection is secure. The battery can be connected to the terminal by pressing the lever; no tools are required. Battery Terminal: The SAE battery terminal connector has 1 connection terminal for wiring. Specifically designed for multi-wire connections, primarily used for SAE/JIS TYPE A rear car battery. Wide Range of Applications: Our battery terminal connectors are suitable for cars, vans, RVs, caravans, trucks, marine batteries, etc. Just make sure you connect the correct poles with the correct polarity. They offer good electrical conductivity and corrosion resistance and work reliably.
