Battery Power Cords

Connect batteries to each other.

Clamp × lug and lug × lug cords also connect batteries to electrical systems.

Cords with post terminals or threaded stud terminals connect two or three batteries in parallel for maximum starting power. Connect the positive terminals together and the negative terminals together to get the combined capacity (in amp-hours) of the batteries—battery voltage remains the same.
