LEICESTERCN Brass Battery Terminals 2pcs — Solid Brass Top-Post Clamps, Marine-Grade Conductive Set

These are a pair of heavy-duty solid brass top-post battery terminals—one positive and one negative—built for reliable electrical contact and corrosion resistance on cars, boats, RVs and lithium systems.

LEICESTERCN designed this two-piece clamp set from thickened solid brass to deliver strong conductivity and long-term durability where conventional lead or zinc terminals fail. The marine-grade finish resists battery acid and oxidation, while the included 5/16" and 3/8" mounting bolts give a secure, low-resistance connection for everyday vehicles and demanding marine or off-grid applications.

How do these brass terminals improve electrical performance?

Solid brass is a superior conductor compared with common lead or zinc alloy terminals, reducing voltage drop and heat at the connection point. Better conductivity helps with dependable engine starts and stable power delivery for accessories.

• Thickened solid brass body for lower electrical resistance
• Improves current transfer, minimizing transmission loss
• Stable contact under repeated start/stop cycles

Are these connectors suitable for marine or corrosive environments?

Yes—the terminals are built to a marine-grade standard with strong resistance to battery acid and oxidation, so they stand up well in humid or salt-prone settings. That makes them a practical choice for boats, coastal vehicles and RVs exposed to the elements.

• Corrosion-resistant brass alloy reduces rust and pitting
• Seals and fasteners sized to limit galvanic wear
• Reliable in both freshwater and salt-air environments

Will these fit my top-post battery or lithium setup?

The clamps are machined for standard top-post batteries—19 mm for the positive post and 17 mm for the negative. They also accommodate many lithium battery top-post configurations used in aftermarket, RV and solar systems, offering broad compatibility.

• Precision fit for standard 19 mm (+) and 17 mm (-) posts
• Compatible with cars, trucks, vans, RVs and many lithium packs
• Clearly marked "+" and "-" for error-free installation

How easy is installation and what hardware is included?

Installation is straightforward: slip the clamps onto the top posts, tighten the included bolts, and check for a snug, vibration-resistant connection. The set ships with both 5/16" (8 mm) and 3/8" (10 mm) mounting bolts for secure fastening and quick serviceability.

• Includes 5/16" and 3/8" mounting bolts for a tight fit
• Top-post design makes swap-outs fast and simple
• Marked polarity reduces installation errors during maintenance

Who is this for? This LEICESTERCN brass terminal set is aimed at vehicle owners, boaters, RV enthusiasts and installers who need a durable, low-resistance top-post connection. It’s a good match for anyone replacing corroded factory clamps, upgrading battery terminations for higher reliability, or preparing an electrical system for marine or off-grid use. If you want a maintenance-friendly clamp that resists acid, salt air and heat while improving current flow, this heavy-duty brass pair is designed for that purpose.
