Abstract: A battery cover connector system for connecting a battery to the wiring harness of an electrical device or accessory includes a cap that fits closely over the top of the battery and a pair of terminal connectors within the cap that are adapted to snap fit onto a respective battery terminal. The system can be readily connected to the battery's positive and negative poles and conversely can be readily disconnected from the battery without the use of tools. The system includes a safety feature that deters a user from improperly making a reverse connection between the battery and the electrical device.
