摘要： Female-style terminals for an electrical power storage device is described herein. The terminals include one or more features that provide a more secure connection between a vehicle connector and the terminal compared to traditional clamp-style connectors. The terminals can include an annular ring or groove. The terminals can additionally or alternatively include a threaded portion and one or more protrusions. The electrical power storage device includes a cover, a portion of the cover adjacent to the terminal includes a keyed section to secure the connector. The disclosed terminals reduce or eliminate movement of the connector relative to the terminal, thereby reducing wear and increasing the performance of the connection.
