Abstract
A jumper cable apparatus to interconnect two batteries is described. The apparatus has a first and second connecting means that releasably engage each other. The first and second connecting means have a polarity-sensitive and current-limiting circuit within each connecting means with one or more colored LEDs, a current-limiting resistor and a piezoelectric alarm. The circuits also indicate when one of the batteries may have an open or short cell. The second connecting means has an electrically insulative, translating block means to reduce the chance of accidental contact with the interior of the connecting means and to reduce the chance of arcing outside of the electrically insulated housing and block means. The apparatus may have an extension cable apparatus to assist jumping the batteries when access to the batteries may be difficult. The housings of the connecting means have bosses and slots to aid in the alignment of the housings and to align the positive cables when the housings are interconnected.
