2pc Car Battery Terminal Clamps Top Post Positive Negative by AUTOMAJOR | Lead clamp set with anti corrosion washers. Fits car truck RV motorcycle marine boat battery terminals

The AUTOMAJOR 2-Pack Car Battery Terminal Clamps are heavy-duty replacement battery cable connectors designed for standard top-post automotive 12V batteries. Each pack includes 1 positive (+) red terminal and 1 negative (-) black terminal — everything you need to replace corroded, broken, or damaged battery cable ends on your car, truck, RV, motorcycle, boat, or other 12V vehicle. Specifications: standard SAE Type A top-post battery terminal sizing, fits virtually all standard automotive 12V batteries. Positive terminal: 17.5mm (11/16 inch) inner diameter. Negative terminal: 15.9mm (5/8 inch) inner diameter. Color-coded red/black for easy positive/negative identification. Heavy-duty lead alloy construction for excellent electrical conductivity and corrosion resistance. Anti-corrosion washers included to prevent acid buildup at the connection points. Battery terminal corrosion is one of the most common causes of starting problems and electrical issues on vehicles. The white/blue/green crystalline buildup that forms on battery terminals is sulfate corrosion — caused by hydrogen gas escaping from the battery and reacting with metal terminals. Over time this corrosion increases electrical resistance, causing slow cranking, intermittent starting, dim headlights, and eventually complete electrical failure. Replacing badly corroded terminals with fresh AUTOMAJOR clamps restores full electrical conductivity. Common reasons to replace battery terminals: heavy corrosion that cannot be cleaned off, cracked or broken clamp body, stripped clamp bolt that no longer tightens, terminal that no longer grips the battery post tightly, after a battery cable replacement, when upgrading from cheap factory terminals to heavy-duty replacements, or when adding accessory power feeds to a vehicle. Installation takes 5-10 minutes per terminal: disconnect the existing battery cable from the battery (always disconnect negative first, then positive), cut off the old corroded terminal from the cable end (leave 1-2 inches of cable insulation), strip 3/4 inch of insulation from the cable end, insert the bare cable into the new terminal, tighten the cable clamp screws securely, slide the new terminal onto the battery post (place anti-corrosion washer between terminal and battery post), tighten the terminal clamp bolt to grip the post firmly, repeat for the other terminal (positive last), and verify proper electrical connection. These terminals fit virtually all standard automotive 12V batteries from major manufacturers including Interstate, ACDelco, Optima, DieHard, EverStart, Duralast, NAPA, AutoZone, Walmart, and Costco brands. Compatible with cars, trucks, SUVs, vans, RVs, motorhomes, motorcycles, boats, ATVs, UTVs, snowmobiles, lawn tractors, riding mowers, generators, and any other 12V vehicle with standard SAE Type A top-post batteries. Backed by AUTOMAJOR — trusted electrical components for automotive, marine, RV, and powersport applications.

• 2-pack of heavy-duty car battery terminal clamps — includes 1 positive (+) red terminal and 1 negative (-) black terminal. Color-coded for easy positive/negative identification. Standard SAE Type A top-post sizing fits virtually all automotive 12V batteries. Positive terminal: 17.5mm (11/16 inch) ID. Negative terminal: 15.9mm (5/8 inch) ID. Heavy-duty lead alloy construction for excellent conductivity and corrosion resistance.
• Battery terminal corrosion is one of the most common causes of starting problems and electrical issues on vehicles. The white/blue/green crystalline buildup is sulfate corrosion that increases electrical resistance — causing slow cranking, intermittent starting, dim headlights, and eventual electrical failure. Replacing badly corroded terminals restores full conductivity and reliable starting.
• Anti-corrosion washers included to prevent future acid buildup at the connection points. Place the included washers between each terminal and the battery post during installation — they slow down corrosion formation and extend the life of your new terminals significantly compared to bare terminal-to-post contact.
• Reasons to replace: heavy corrosion that cannot be cleaned off, cracked or broken clamp body, stripped clamp bolt that no longer tightens, terminal that no longer grips the battery post tightly, after a battery cable replacement, when upgrading from cheap factory terminals to heavy-duty, or when adding accessory power feeds to a vehicle.
• Compatible with virtually all standard automotive 12V batteries from major manufacturers (Interstate, ACDelco, Optima, DieHard, EverStart, Duralast, NAPA, AutoZone, Walmart, Costco). Fits cars, trucks, SUVs, vans, RVs, motorhomes, motorcycles, boats, ATVs, UTVs, snowmobiles, lawn tractors, riding mowers, generators, and any 12V vehicle with standard SAE Type A top-post batteries. Always disconnect negative terminal first when removing, connect negative last when reinstalling.
