LEICESTERCN Solid Brass Battery Terminals 2-Pack — Top-Post Positive & Negative Clamps, Marine-Grade Corrosion-Resistant

These two solid-brass top-post battery terminals provide a corrosion-resistant, high-conductivity connection for cars, trucks, boats, RVs and lithium battery systems.

Built from thickened solid brass and engineered for standard top-post batteries, the LEICESTERCN 2-piece terminal set replaces worn or corroded clamps with marine-grade hardware that resists acid, oxidation and salt air. The kit includes one positive and one negative clamp, clearly marked and fitted with 5/16" (8mm) and 3/8" (10mm) bolts to give a secure, low-resistance attachment for everyday vehicles and heavy-duty applications alike.

How do these brass terminals improve electrical performance?

Solid brass offers better conductivity than common lead or zinc clamps, which reduces voltage drop and keeps starter and accessory loads performing closer to design. Thicker metal and tight fasteners lower contact resistance and maintain steady current flow under load.

• 100% solid brass body for superior conductivity
• Thickened alloy construction reduces transmission loss
• Tight clamp design minimizes voltage distortion during starting

Are these terminals suitable for marine and coastal use?

Yes — the connectors are made with a corrosion-resistant brass alloy intended to withstand battery acid, humidity and salt exposure. They’re described as marine grade, making them a practical choice for boats, yachts and seaside vehicles where standard clamps quickly degrade.

• Corrosion-resistant brass reduces oxidation over time
• Acid-tolerant finish protects contact surfaces
• Strong bolts resist loosening in vibration-prone environments

Will these fit my battery and how easy are they to install?

The clamps are machined for standard top-post batteries: a 19mm positive post and a 17mm negative post. Installation is straightforward — each clamp is marked with "+" or "-" and secures with included 5/16" (8mm) and 3/8" (10mm) mounting bolts for a vibration-resistant connection.

• Precision fit for standard top-post terminals (19mm/17mm)
• Clear polarity marks to prevent installation errors
• Included bolts provide a secure, low-vibration hold

Can these connectors be used with lithium or high-capacity battery setups?

The heavy-duty brass and robust clamping hardware make these terminals suitable for many high-capacity batteries, including many lithium top-post configurations. Always verify terminal size and battery manufacturer recommendations before installation to ensure compatibility.

• Compatible with common lithium top-post battery designs
• High-strength brass copes with elevated current demands
• Recommended to confirm terminal geometry with your battery model

Who is this for: These LEICESTERCN brass battery terminals are aimed at vehicle owners, marine operators and RV enthusiasts who need a reliable top-post connection that resists corrosion and improves electrical performance. They suit DIYers replacing corroded clamps, fleet maintenance crews upgrading durability, and off-grid users pairing heavy-duty connectors with lithium or deep-cycle batteries.
