Weatherproof Desulfating Battery Charger/Maintainer
Special edition Optimate 4 Dual Program that has been optimized for CAN-bus equipped BMW motorcycles
Charger comes preprogrammed with the CAN-bus charging and maintaining program
Previously when the battery in a CAN-bus system was fully charged and a charger moved into the maintenance program, the CAN-bus system would automatically disconnect the charging circuit and require intervention from the user to reactivate
With the Optimate 4 Dual program it is now possible to automatically charge and maintain CAN-bus equipped motorcycles via their convenient external 12V charging port, without use of the ignition key or reactivation
Includes CAN-bus connection cord for use with the OEM 12V charging port and battery clip set for bench charging
