[Compatible with DeWalt 20V MAX Batteries] The jumper cables are compatible with DeWalt 20V MAX batteries. When your car battery dies and leaves you stranded, it can be difficult to find someone to help jump-start the car. You can conveniently start your vehicle using the power of an available cordless tool battery. Specifications: 8-gauge booster battery jumper cable for starting dead or weak batteries. Suitable for trucks, SUVs, full-size cars, midsize cars, 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. Insert the DeWalt 20V MAX battery into the adapter and ensure it is securely locked in place. 3. Attempt to start the vehicle. 4. After successfully starting the vehicle, disconnect the jumper cable from both the car battery and the tool battery. Note: For best results, use a battery charged to at least 50%. If the first start attempt fails, wait a few minutes before trying again. Once the engine starts, remove the cable within 30 seconds. The jumper cable features an insulated handle to help prevent electric shock and enhance user safety. Color: Yellow Material: ABS Package Contents: 1 x Car auxiliary starter
