Package Includes: These covers include 2 positive battery terminal caps, 2 negative terminal caps, and 4 washers, providing a complete set for installation. The negative caps feature an inner diameter of 0.65–0.68 inches, while the positive caps measure 0.71–0.76 inches, with an overall height of 0.71 inches
Practical Function: These covers reduce direct exposure of connector terminals to air, helping lower the possibility of short circuits between the battery and alternator. They also protect unused positive and negative posts, offering effective dust resistance and electrical insulation during daily vehicle operation
Quality Material: These terminal covers are made from high-strength PC plastic that resists impact and does not break easily when subjected to force. The material also provides heat resistance and flame retardancy, allowing stable performance even when used in high-temperature engine environments
Wide Application: These battery terminal caps fit standard top-post batteries with 19 mm tapered positive posts and 17 mm tapered negative posts. They work with battery terminals and power junction boxes, making them suitable for cars, trucks, and use with alternators or starter equipment
Easy to Use: These kits include washers that support efficient and safe use during setup. First, clean and dry the battery terminals thoroughly. Then, insert the protective caps onto the corresponding battery posts, with red for positive and black for negative, and press them firmly into place
