For an optimal connection between battery terminals and the polypropylene of the battery cover, the burnished areas of the labyrinth and the self-sealing labyrinth rings (so-called indentations) provide for the shrinking of the polypropylenes. Through the labyrinth-shaped implementation of the battery terminals (“advanced undercut”), leakage of acids and gases are prevented. To guarantee as long a protection against oxidation as possible and an improved look, our battery terminals are generally burnished over the entire cone area. In this way, our products have an entire battery life. Rely on our quality and be sure that you have made the right choice with our products.
