The Optimate 4 Dual Program 1A is the most advanced and trusted battery charger on the market today. This version of the Optimate 4 line trickle chargers is for motorcycles with CAN-bus.
This3rd model incorporates all benefits that made its predecessors so successful. These include automatic keyless activation and continuation of service until the charger is disconnected, and safe low voltage pulse desulphation, it also adds a number of further benefits. The power circuit is now even more efficient, delivering a 1 amp charging current and improvements in the software control mean that charging is now even faster. In addition, the new visual LED instructions on the charger itself allow the user to follow the charging process at a glance.
The Optimate 4 Dual has two charging programs; the BMW CAN-bus program and the standard program. The BMW CAN-bus program charges and maintains the battery of any BMW motorcycle via the standard 12V-DIN power socket of the motorcycle. Unlike the original Optimate 4 charger, this CAN-bus edition is already set to the BMW CAN-bus program by default.
The otherwise optional DIN plug O-02, which is necessary for making this connection, is included in this edition instead of the fixed waterproof connection O-01.
When using the BMW CAN-bus program, the Optimate sends out a signal which causes the BMW CAN-bus system to "open" the 12V connection so that the battery can be charged. When you connect the Optimate to your BMW motorbike in the standard program, the Optimate sends no signal and the 12V-DIN connection remains "closed" and the battery will not be charged.
With the standard program you charge and maintain all motorcycle batteries with the supplied alligator clamps.
If your motorcycle has a 12V connection (a DIN or a cigarette lighter socket), you can use this cable.
Please note: check whether the 12V connection is directly connected to the battery. How to check this? Connect an accessory to the socket, do NOT turn on the ignition and check if the accessory is working/recharging.
A Ducati motorcycle can be connected with this optional cable.
The Optimate 4 is a safe device, you run no risk of overcharging your battery. The weatherproof housing can be attached to a wall, which is convenient if you always use it at the same location.
