Set includes two car battery terminals with anti-corrosion pads and Allen keys for faster installation. Key benefits Reliable electrical contact: High-conductivity terminals reduce voltage distortion and transmission losses so accessories and starters get consistent power. Durable construction: Brass terminals and aluminium-alloy handles resist rust and corrosion for long-term use and reliable connections. Safer, faster installation: Color-coded terminals (red = positive, black = negative) make polarity obvious and reduce wiring errors; included Allen keys speed assembly. Flexible connections: Large-calibre, thickened cable clamps and four-way (4-way) connection design accept multiple interface products, simplifying accessory wiring and upgrades. Battery protection: Anti-corrosion pads help prevent acid damage and extend battery life. What’s included Two battery terminals (positive and negative) Two anti-corrosion pads Allen keys for installation Materials and performance Terminal material: high-quality brass for good conductivity Handle material: aluminium alloy — comfortable grip, insulated and safe Design: thickened clamps and large-calibre opening for heavy cables and stable contact Connections: four-way interface per terminal for multiple accessory attachments Compatibility and function Designed for automotive battery terminals; the large-calibre, four-way design supports a wide range of interface products and accessory leads commonly used with car batteries. Suitable for long-term installation or as a replacement set to restore reliable battery connections. Practical use scenarios Replace corroded or loose factory terminals on a car battery to restore reliable starting performance and reduce electrical losses. Add or reorganize accessory wiring (audio ground/positive, auxiliary power, sensors) using the four-way connections instead of splicing into factory terminals. Use during maintenance to protect the battery from corrosion with the included anti-corrosion pads and to speed up reassembly with the supplied Allen keys. Simple installation notes Identify polarity by color: red = positive, black = negative. Tighten clamps with the supplied Allen keys for a secure connection. Install anti-corrosion pads between terminal and battery post to reduce corrosion and extend battery life. This set delivers reliable conductivity, corrosion protection, clear polarity identification, and flexible connection options for automotive battery applications.
