A standard automobile battery is modified to contain a set of retractable jumper cables, pre-attached to the positive and negative terminals of the battery. The cables are housed in a separate chamber formed either internally in a modified battery casing or externally in an auxiliary structure augmenting the usual casing. A bulb is connected across the cables to provide visual indication of good cable contact. Jumper clamps are made luminescent. |
