The Optimate 4 Can-Bus edition is a charger that successfully communicates with CAN-bus electrical systems. CAN-bus is two-wire system connecting every electrical device on the motorcycle to the central MCU (ZFE microprocessor), including the 12V accessory power socket. The 12V accessory socket is "˜live' (hot - connected to the battery) IF:1. Motorcycle ignition is on or soon after it has been turned off. (delayed "˜off', socket only). 2. If a CAN-bus friendly charger communicates successfully with the ZFE MCU. This allows charge and maintenance of the battery through the 12V socket and without having to directly access the battery. OptiMate 4 DUAL PROGRAM has solved the communication problems with Can.Bus motorcycle models and will automatically charge and maintain the battery. The MCU draws power from the motorcycle battery for the alarm, memory and clock. It turns off when the battery is low, but by then the battery may be too flat to crank the engine. If you leave a lead-acid battery discharged for too long, it will become sulphated and unable to accept any charge through the 12V socket or even directly. OptiMate 4 Dual Program can save a low voltage sulphated battery: Remove the battery from the vehicle to SAVE (desulphate) it. Select program 1 for the high voltage desulphation mode (not active during program 2 CAN-bus mode) and save the battery. After SAVING, re-fit to the vehicle. Do not forget to once again select CAN-bus mode as the DIRECT charge mode does not work through the CAN-bus controlled 12V socket. FYI: The BMW branded chargers have no SAVE (desulphation) mode which is absolutely necessary to save an AGM / GEL battery from a low voltage, sulphated state.
