Review: Perfect for Standard Car Battery Clamp Sizes - These are perfect for standard top-post car batteries. But the clamp I needed it for is a strange, thin-walled clamp that wouldn't open far enough for the shim. Yet fully tightened it was moveable by hand. Standard clamps would be no issue. These are nicely made and will be a great solution for regular-sized clamps. I am keeping these - confident in their value and should myself or a friend need one.
Review: Useless junk way too small - Ridiculous and completely useless. These “shims” are too small. Smaller than the battery terminal and too thick. As is being too thick, they won’t work under a battery clamp as it will take up too much space on maybe half a side of the terminal and make for poor contact and unable to secure the factory clamp without deforming it. Useless junk.

## Features

- 【Practical Functions】: This car battery adapter socket is designed for connecting both positive and negative ends of the battery. It converts the battery's positive terminal to negative, ensuring a safe electrical connection for damaged or undersized batteries. It effectively addresses issues of battery post and terminal wear, and poor battery fit.
- 【Reliable Material】: Crafted from high-quality pure lead, this car battery adapter socket is rust-resistant and corrosion-resistant. Lead, a soft metal with toughness and malleability, provides excellent conductivity, making it an ideal material for electrical systems.
- 【Size Information】: The upper diameters of these car battery terminal adapter sleeves approximately 0.6 inches, while the lower diameters approximately 0.7 inches. Please ensure a proper fit before ordering. Compact and portable, they occupy minimal space for easy carrying and use.
- 【Easy to Use】: The car battery post spacer is easy to handle, you may need to use a tool (such as tweezers) to properly adjust the diameter of the sleeve to better fit the top battery post before use, and then just install the sleeve into the top battery post. Save your time and energy and provide convenience.
- 【Wide Application】: The automotive battery adapter covers are suitable for top post batteries or cables, side post batteries or cables, and are suitable for battery terminals in most cars, boats, small yachts, RVS, trucks, and other household devices.
