This is an Optimate 6. I mainly used it as a charger for my car. The original box and instruction manual are not included. You can easily charge your car battery by permanently connecting the vehicle-side cable (image 3) to the battery and then plugging it into the socket when charging! There are some minor scratches from use, so please consider this before purchasing. Operation has been confirmed. The instruction manual can be viewed online. Thank you. - Model: Optimate 6 - Voltage: 12V - Functions: Automatic battery charger, tester, maintainer - Country of Manufacture: Belgium
