Description

Self-Clamping Battery Clamps – Professional Workshop Grade

Brief Overview

This pair of self-clamping battery clamps delivers reliable, hands-free battery post connection for automotive workshops and mobile service operations. The brass-plated metal contacts and spring-loaded clamping mechanism ensure consistent electrical contact without manual adjustment. These clamps are engineered for repeated use in diagnostic work, battery testing, and temporary power connections. For shops requiring multi-tool solutions, consider pairing these with battery terminal extraction tools to streamline battery service workflows.

Key Features

  • Self-Clamping Design: Spring-loaded mechanism automatically secures to battery posts without manual tightening
  • Color-Coded Polarity: Red (positive) and blue (negative) hard plastic shells with embossed polarity marks for quick identification
  • Brass-Plated Contacts: Gold-colored plated metal clamp jaws provide corrosion resistance and reliable electrical continuity
  • Dual Voltage Rating: Supports both 12V and 24V battery systems
  • Heavy Current Capacity: 430A continuous rate; 1,000A crank/surge rating handles high-demand applications
  • Cable Compatibility: Fits 4-6 AWG wire terminals
  • Robust Construction: Zinc-plated metal components with serrated contact surfaces prevent slipping
  • Compact Form Factor: Tapered design with rear-facing hardware for clean installation and storage
