The OptiMate 4 Quad Program charger is a universal tool for motorcycle battery care. It has automatic programmes for diagnosing, reviving, charging and maintaining the vehicle's battery. This can be connected directly, but also by means of one of the programs via the 12V connection of the motorcycle equipped with a CAN bus. With the OptiMate 4 Quad Program, after selecting one of the 4 programs, the battery is automatically charged and maintained. This mode includes low voltage revive pulses for even more effective charging of very discharged and sulphated batteries. Select programme 1 or 3 to charge the battery directly or via a live (hot) 12V socket, or programme 2 or 4 to charge via a BMW CAN bus-controlled 12V socket.
