Specifications: 8-gauge booster battery jumper cables for starting dead or weak batteries. Suitable for trucks, SUVs, full-size, midsize, and compact cars. Instructions for use: 1. Connect the red clamp to the positive terminal (+) of the vehicle battery and the black clamp to the negative terminal (-). 2.
