[Compatible with 20V MAX Batteries] The jumper cables are compatible with 20V MAX batteries. When your car battery dies, you can conveniently jump-start the vehicle using a compatible cordless power tool battery. Specifications: 8-gauge booster cable for starting weak or discharged batteries. Suitable for trucks, SUVs, full-size cars, midsize cars, 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. Insert a fully charged 20V MAX battery into the adapter and ensure it is securely locked. 3. Attempt to start the vehicle. 4. After successful engine start, disconnect the clamps in reverse order: black first, then red. Note: For best results, use a battery with at least 50% charge. If the first attempt fails, wait a few minutes before retrying. The jumper cable features insulated handles for user safety.
