The terminals on any battery are one of the most important parts that can boost or reduce efficiency. These are the external metal contact poles to which contact wires are attached and help carry the power to where required. There is usually a buildup of chemical deposit on these poles which can greatly reduce the efficiency of this part. For the NS-40 type of battery the Small Terminal Caps are perfectly suited to keep them protected. These are made of complete acid resistant material and are highly durable. JK Ceraplast manufactures these small caps and the product has a high demand with all level of customers. The common colors available are Red and Black.
