ABSTRACT:
An electrochemical cell having an on-cell tester for visually indicating the condition of the cell is provided with an electrically conductive metal ring pressed onto the negative terminal at the crimp seal end of the cell, to permit the tester lead to make an electrical contact with the negative terminal without shorting across the positive terminal of the cell. The ring has a cylindrical wall portion or gripping means which frictionally grips a corresponding mating cylindrical wall potion on the negative terminal and also has a flange portion adjacent the positive terminal. A layer of electrically insulating material disposed between the flange and positive terminal prevents electrical contact between the terminals. The tester lead is either permanently electrically connected to the ring or intermittently connected by the user, depending on the type of tester used.
