Overview<\/div>\n\n\n\n

A verification test was conducted to confirm that no leakage current occurs from the installed battery terminal cover when a high direct current is applied to the battery terminal.<\/p>\n\n\n\n

Test Method Details<\/div>\n\n\n\n

Although batteries installed in automobiles and similar vehicles typically operate at 12V or 24V, this test deliberately applied a high DC voltage of 1,000V to verify whether any leakage current would occur externally from the battery terminal cover.<\/p>\n\n\n\n

In this test method, the entire surface of the battery terminal cover (test sample) was covered with conductive copper foil tape. The cover was then mounted onto a battery terminal that had been crimped to a 60sq cable. A DC voltage of 1,000V (1kV) was applied for one minute between the cable and the copper foil on the cover to determine whether any leakage current would occur from the cover.<\/p>\n\n\n\n

(Note: The applied voltage and duration in this test were determined independently by our company and are not based on any external standards.)<\/p>\n\n\n\n

Test Results<\/div>\n\n\n\n

As shown in the photo on the right, even after DC 1.00kV was applied (left-side value on the tester display) for approximately one minute (right-side value), the leakage current remained at 0.00mA (center value), confirming that there was no external leakage current from the battery terminal cover. The target application time was one minute.<\/p>\n\n\n\n

This test was conducted under voltage conditions far beyond those encountered in normal use. Since our similar battery terminal covers are made from the same material and have equivalent wall thickness, they can also be considered to possess sufficient dielectric strength.<\/p>\n\n\n\n
