Lead Battery Terminals (Pair) with Fixed Bolt and Copper Nut

This pair of lead battery terminals is designed to provide a dependable, low-resistance connection between your battery and your vehicle or boat’s electrical system. Made from high-quality lead alloy, these terminals offer both durability and excellent electrical conductivity. The soft, malleable lead conforms tightly around the battery posts, minimizing resistance and voltage drop across the connection.

Features and benefits:

• Superior Conductivity: The lead alloy construction allows maximum current flow to and from the battery, which is especially critical when cranking engines or powering high-draw equipment. You’ll get a solid, uninterrupted connection without overheating or power loss at the terminal.
• Convenient Fixed Bolt: Each terminal has an integrated bolt cast into its body. This means you won’t juggle separate bolts during installation – simply slip your cable lug onto the stud and tighten the included nut. The fixed bolt provides stability and prevents the cable from twisting or loosening, even under engine vibration or choppy seas.
• Copper-Coated Nut for Corrosion Resistance: The provided nut features a copper coating that wards off corrosion and enhances electrical contact. Copper is an excellent conductor and forms a tarnish-resistant surface. This ensures your connection remains strong and efficient over time, even in damp or salty conditions (ideal for marine or off-road use).
• Universal Fit and Compatibility: The set comes with two terminals – typically one with a slightly larger inner diameter for the positive post and one for the negative (standard “+” post ≈19 mm, “-” post ≈17 mm). This makes the kit suitable for a wide range of batteries found in cars, boats, RVs, solar battery banks, and more. Whether you’re replacing corroded car battery clamps or outfitting a marine dual-battery setup, these terminals have you covered.
• Easy Installation & Maintenance: Installing these terminals is straightforward: remove the old connectors, place the new lead terminals onto the battery posts and tighten them securely, then attach your cable lugs onto the fixed bolts and fasten the copper nuts. It’s recommended to periodically check the terminals for tightness and re-tighten if necessary. You can also apply a thin layer of battery terminal grease after installation for extra protection against oxidation and to maintain optimal conductivity.

With these lead battery terminal clamps, you ensure peace of mind that your electrical system has a solid foundation. Whether you’re starting a boat engine in saltwater or powering an RV on a long trip, these terminals will keep the current flowing reliably. They withstand extreme temperatures and high current loads, making them an essential component for maintaining any battery system. By investing in quality terminals, you protect both your battery and your vehicle’s electronics from voltage drops and the risks associated with poor connections (like overheating or intermittent power). It’s a small upgrade that delivers significant benefits in performance and safety.
