Reshape Secure Battery Connections with Professional Conductive SolutionsProduct AttributesColors: SilverSizes: 0.68×0.63×0.63 inch, 0.74×0.68×0.63 inchApplicable Range: 6V/12VWeight: 1.22 ozMaterial: LeadPackaging: 2* Car Battery Post ShimsPackage Sizes: 4.33×3.34×0.63 inchProduct Feature & Functions1. The core function of automotive battery shims is to convert the gap between cable connectors and battery terminals into direct metal-to-metal contact, enhancing electrical conductivity2. Made from relatively soft material, they undergo slight deformation when tightening cable clamps, better adapting to irregular surfaces and increasing effective contact area

• Purchase Notes: The battery post shim set includes two sizes: Small: Bottom diameter 0.68″ x Top diameter 0.63″ x Height 0.63″; Large: Bottom diameter 0.74″ x Top diameter 0.68″ x Height 0.63″. Before buying, please measure your battery post diameter using calipers
• Core Function: Specifically designed to address gaps between battery terminals (positive/negative) and cable connectors caused by wear or differing specifications. The car battery shim fills these voids, providing a stable, secure connection between terminals of varying thicknesses and cables
• Lead Material: Automotive battery post shims are manufactured from high-purity lead. Not only does it possess excellent ductility, but more importantly, it offers superior electrical conductivity. This provides maximum assurance for stable current transmission
• Application Scope: Automotive battery shims can be used for side-post batteries or cables as well as top-post batteries. Whether for passenger cars, SUVs, RVs, or other household equipment battery terminals, they provide a solution whenever battery connection loosening occurs
• Easy Installation: Battery terminal shims feature a convenient open-ended (C-shaped) design. During installation, simply slip them over the battery terminals. For fine adjustments, use pliers to gently squeeze/expand the opening to achieve optimal contact with the terminal
