    Optimate 4 Battery Charger - Dual Program, Canbus Edition

    The OptiMate 4 saves neglected, deep-discharged batteries that other smart chargers cannot. It is ideal for all AGM, GEL and standard filler cap batteries from 3 to 50Ah. It comes with a IP64 weatherproof sealed enclosure with built-in mounting option. The canbus edition is compatible with both conventional or CAN-bus motorcycle electrical systems. It can switch between STANDARD or CAN-bus programs with a simple five-step procedure (charger comes pre-programmed STANDARD for conventional electrical systems); you can switch programs as many times as you want. LED indication confirms the CAN-bus program is active.

    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.

    Provides optimal maintenance of your battery during long-term storage, achieved by its gentle maintenance cycle, which automatically allows the battery to rest for 30 minutes of each hour of the maintenance cycle while it remains connected


    • SAE weatherproof connections
    • Control panel with 10 LEDs display all vital battery information
    • Cable bushings avoid insulation stress in ultra-cold temperatures
    • Includes fused eyelet connector for permanent mounting and battery clip set for bench charging

    Very pleased with the Optimate 4. Works on my 1981, 2000, and 2018 BMW's. All using the accessory plug in. Just what I wanted.

    I bought this for my ‘22 GSA 1250 and it works beautifully. The ease of use and utility is great for the price when comparing to the BMW charger that will not maintain as well. Highly recommend. The only complaint is the light sequence is ridiculously convoluted. If possible 0.5 star reduction. Otherwise the product is great.
