The first battery terminal corresponds to the first coupler of the coupler bridge; the second battery terminal corresponds to the second coupler of the coupler bridge; and when the first edge faces towards the battery, the first height of the first section is configured to: restrict the first coupler from coupling to the second battery terminal; and restrict the second coupler from coupling to the first battery terminal. The second section of the coupler bridge comprises a second height and a second edge at a different side of the coupler bridge than the first edge; and only when the second edge faces towards the battery, the second height of the second section is configured to: permit the first coupler to couple to the first battery terminal; and permit the second coupler to couple to the second battery terminal. The first coupler comprises a first color; and the second coupler comprises a second color. The first battery terminal comprises the first color; and the second battery terminal comprises the second color. The electrical terminals of the battery comprise a first battery terminal end and a second battery terminal end; and the first and second battery terminal ends are positioned a terminal height over the battery. The first height of the first section is configured to position the first and second couplers above the terminal height over the battery when the first section of the coupler bridge contacts the battery. The first and second couplers are positioned substantially at the terminal height over the battery when the second section of the coupler bridge contacts the battery. The coupler bridge further comprises an elevation distance from the first edge of the first section to at least one of the first or second couplers; and the elevation distance is greater than the terminal height. Preferred Method: In manufacturing the electrical connector for the target terminal range of the battery, forming a connector body further comprises: forming the second segment to position an interface set within the target terminal range; and forming the first segment to position the interface set outside the target terminal range; and the interface set comprises the first and second interfaces. The method further comprises providing a battery comprising a third interface and a fourth interface; where: the third interface and the fourth interface extend from the battery to the target terminal range; the third interface is separated from the fourth interface by a terminal distance; and the first interface is separated from the second interface by the terminal distance. Coupling the first interface occurs simultaneously with coupling the second interface. Also, coupling the first interface and coupling the second interface occur simultaneously with forming the connector body. The method as well comprises: providing a connection assistance mechanism coupled to the connector body; where the connection assistance mechanism comprises at least one of: one or more grip ridges; or a pull-tab. Providing the connection assistance mechanism occurs simultaneously with forming the connector body. Preferred Mechanism: In the battery connector mechanism for coupling with electrical terminals of the battery, the first section further comprises a first breadth; the electrical terminals of the battery comprise a third connector and a fourth connector; the first and second connectors are located at substantially opposite ends of the structure; the first connector is separated from the second connector by a first magnitude; the third connector is separated from the fourth connector by the first magnitude; the first and third connectors comprise a first polarity; and the second and fourth connectors comprise a second polarity. The first connector is physically incompatible with the fourth connector; and the second connector is physically incompatible with the third connector. The first breadth is configured to position the first and second connectors above the third and fourth connectors when the first border contacts the battery. The first breadth of the first section is configured to restrict both the first connector from coupling to the fourth connector, and the second connector from coupling to the third connector, when the first border contacts the battery; and the first and second connectors are configured to align with the third and fourth connectors only when the first border of the first section faces away from the battery.
