The jump starter adapter is compatible with Makita 18V batteries BL1830, BL1840, BL1850, and BL1860 series (Battery not included). Designed for jump starting 12V car batteries using a power tool battery, this booster provides reliable performance for cars, trucks, SUVs, and light recreational vehicles. Features 11-gauge heavy-duty jumper cables with strong alligator clamps that feature jagged teeth and powerful springs for secure connections. The clamps provide excellent grip on both top-post and side-terminal 12V batteries. Insulated handles and non-conductive rubber construction help prevent electric shock and enhance user safety. Dual-grip design ensures better conductivity, tension control, and secure handling during use. Tangle-free cable design allows for easy storage and deployment. Instructions: 1. Charge the vehicle battery for approximately 2 minutes using the connected tool battery. 2. Connect the red clamp to the positive terminal (+) of the car battery and the black clamp to the negative terminal (-). 3. Insert the Makita 18V battery into the adapter and ensure it is securely locked in place. 4. Start the vehicle. 5. Once the engine starts, disconnect the adapter from the battery terminals.
