Battery Clamp (Large Size) - Industrial Heavy-Duty High-Current Battery Terminal Clamp (100 pcs/lot)

Product Overview
The Battery Clamp (Large Size) is a heavy-duty battery connection tool engineered for high-current applications. It features a robust pure copper clamp body​ and distinctive red insulated handles, offering a solid structure and exceptional electrical conductivity. With a standard specification of Large Size, this product is suitable for trucks, construction machinery, marine vessels, and large backup power systems where reliable power transmission is critical. Its core function is to provide a secure grip and highly efficient electrical connection​ between battery terminals and cables, ensuring safe operation with minimal resistance during high-current flow. The displayed batch of 100 pieces​ demonstrates our stable, large-scale supply capability. As a source manufacturer, we offer comprehensive customization from dimensional specifications and surface finishes to branding, and fully support OEM/ODM private-label cooperation.
Primary Uses
  • Heavy-Duty Vehicle Starting & Charging: Specifically designed for battery connection, jump-starting, and charging maintenance for large vehicles like trucks, buses, tractors, and excavators.
  • Construction Machinery & Marine Electrical Systems: Applicable for connecting starter battery banks and auxiliary power cables in large equipment and vessels.
  • Backup Power & Generator Sets: Used for battery connections in large backup power systems such as UPS units and diesel generators.
  • Industrial Equipment & Repair Workshops: Serves as a standard workshop tool for various high-current testing, equipment repair, and power transfer tasks.
Materials and Construction
  • Clamp Body & Conductive Parts: The main body is constructed from high-purity forged copper or thick-walled copper alloy, ensuring excellent conductivity, mechanical strength, and corrosion resistance. The gripping jaws are reinforced for superior clamping force.
  • Insulation & Handles: The red PVC or rubber insulated handles​ are ergonomically designed for comfortable grip and provide reliable insulation protection against accidental short circuits.
  • Connection & Spring: Equipped with a high-tension spring​ inside to maintain a persistent, secure grip that resists loosening. The cable connection end typically features a bolted crimp style for maximum contact area and reliable connection.
  • Surface Finish: Critical conductive areas can be tin-plated or silver-plated to further enhance corrosion resistance and reduce contact resistance.
Core Functions and Features
  • Large-Size Heavy-Duty Design for High Current: The Large Size specification​ translates to a larger contact area and thicker conductive material, specifically optimized to carry hundreds of amps of cranking or continuous current, far exceeding the capacity of ordinary small clamps.
  • Pure Copper Material, Ultra-Low Resistance: The use of high-purity copper​ as the core conductor guarantees minimal bulk and contact resistance from the source, significantly reducing power transmission loss and heat generation, ensuring connection safety and efficiency.
  • Powerful Grip, Anti-Slip & Anti-Loose: The optimized jaw serrations combined with a robust spring ensure a firm hold on battery terminals even under vehicle vibration or rough conditions, effectively preventing starting failures or arc hazards due to poor contact.
  • Rugged, Durable & Safely Insulated: The all-metal construction is sturdy and reliable for frequent use. The bright red insulated handles are not only aesthetically pleasing but also provide clear identification and prevent accidental contact, enhancing operational safety.
