Patent ID: 8096825

Claim:
A coupler system configured to couple to electrical terminals of a battery, the coupler system comprising: a coupler bridge comprising: a first section comprising: a first height; and a first edge; a second section adjacent to the first section and opposite the first edge, the second section comprising: a second height; and a second edge; a first coupler coupled to the second section of the coupler bridge; and a second coupler coupled to the second section of the coupler bridge; wherein: the first and second edges are at opposite sides of the coupler bridge; the electrical terminals of the battery comprise: a first battery terminal with a first battery terminal end; and a second battery terminal with a second battery terminal end; the first and second battery terminal ends are positioned at a terminal height over a battery surface of the battery; and when the first edge of the coupler bridge contacts the battery surface: the first height of the first section is configured to position the first and second couplers past the terminal height over the battery surface to restrict the first and second couplers from being electrically coupled to the electrical terminals of the battery.
