Automotive and marine battery connectors designed to deliver strong, corrosion-resistant electrical connections, introduced as Ampper Brass Battery Terminals. Secure connections reduce the risk of failed starts and lower maintenance stress for vehicle and boat owners. Are these clamps the right fit for everyday motorists and marine users?

⚡ At a Glance
  • Connection Reliability: Brass construction increases strength and helps resist corrosion for stable conductivity
  • Best for: Car, boat and RV owners needing sturdy, standard top-post battery connections
  • Not ideal for: Batteries with non-standard or side-post terminals

Brass top-post connectors with clear polarity markings and pre-cut threads. Compatible with standard 19 mm positive and 17 mm negative tapering top posts.


Long-lasting corrosion resistance - thanks to brass construction

Brass resists oxidisation more effectively than plain steel, helping to maintain a low-resistance contact at the terminal. The material choice lowers the rate of corrosion in damp or marine environments.

Fewer cleaning cycles and steadier electrical contact mean more reliable engine starts and reduced upkeep for boats and vehicles.

Quicker, neater installation - with pre-cut threads and marked polarity

Terminals arrive with threads already formed and clear + and - markings, allowing bolts to be secured directly without chasing threads. Markings reduce the chance of reversing polarity during fitment.

Fitting is faster and less fiddly, making roadside or workshop installations simpler and reducing the risk of wiring mistakes.

Versatile connection options - with support for extension, parallel and ground connections

Design supports battery extension, parallel battery links and dedicated ground connections, and matches standard top-post taper sizes for positive and negative posts. The pair format covers most dual-terminal setups.

Handy for joining batteries, creating parallel banks or adding sturdy earth points on cars, RVs and boats.

❓ Frequently Asked Questions

Q: Are these terminals compatible with side-post batteries?

A: No, compatibility is for standard top-post batteries with a 19 mm positive taper and 17 mm negative taper, side-post batteries are not covered by the specification.

Q: Will these terminals resist corrosion in marine use?

A: Yes, brass construction and the product description stating reduced corrosion make them suitable for boat and marine applications, helping maintain conductivity in damp conditions.

Q: How easy are they to install?

A: Threads are already cut on the terminals and polarity is clearly marked, which speeds up fitment and cuts the chance of mis-wiring according to user feedback.

🏆 Our Verdict

Ideal for car, RV and boat owners who need dependable top-post battery connections. Sturdy brass construction, pre-cut threads and clear polarity markings make installations quicker and reduce upkeep. While there are cheaper alternatives, the robust build and corrosion resistance make these terminals a solid long-term choice for regular use.
