Abstract: An electrochemical cell is provided that has a negative terminal cover with a hole therein or a raised portion with notches therein to provide adequate air ingress during the coating of a non-conductive material on the raised portion of the negative terminal. The addition of the hole or notches in the negative terminal cover prevents a vacuum from forming and thereby prevents migration of the non-conductive material toward the center of the negative terminal cover. The process of making an electrochemical cell with a negative terminal cover that has a hole therein or has a raised portion with notches therein is also provided.

Abstract: A system and method of arranging products, such as batteries, in a display package according to a desired orientation with efficient space utilization. The method includes providing products to be packaged, and applying an invisible orientation marking on each of the products. The orientation marking is visible when illuminated with ultraviolet light and is generally invisible to consumers under normal ambient light conditions. The method also includes illuminating the products with ultraviolet light, scanning each of the products, detecting the orientation marking on each of the products, orienting each of the products based on the detecting steps, and disposing each of the oriented products in a package so that the products have a desired orientation.
