When your car battery dies, you can conveniently start your vehicle using a compatible cordless tool battery. Specifications: 8-gauge booster battery jumper cables for starting weak or dead batteries. Suitable for trucks, SUVs, full-size, midsize, and compact cars. Instructions for use: 1. Connect the red clamp of the jumper cable to the positive terminal (+) of the vehicle battery and the black clamp to the negative terminal. 2.
