WEATHERPROOF DESULFATING BATTERY CHARGER/MAINTAINER
The Wunderlich OptiMate 4 battery charger is a universal tool for the maintenance of your motorcycle battery. It features an automatic program that will diagnose the condition of the battery and recondition and charge the battery based on requirements. Even a completely dead battery can most often be put back into top condition with this charger! It can be connected to the battery indefinitely, without any problems, so that your bike is always ready to go when you are. That makes this charger ideal for long periods of non-operation.
The technology incorporated into this charger allows you to connect it to the standard BMW DIN accessory outlet, even on CAN-bus models, without incident. The charger is supplied with alligator clips and also a BMW style DIN plug, either of which can be connected to the output lead through the shielded, waterproof SAE connector. As an accessory, you can also purchase a direct battery connection lead if you desire a direct battery connection or for convenient use on other vehicles.
With some battery chargers, when the battery in a CAN-bus system is fully charged and a charger moved into the maintenance program, the CAN-bus system automatically disconnects the charging circuit and requires intervention from the user to reactivate. With the OptiMate 4 Dual Program Charger it is 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.
Also works for any other 12 volt battery, not only CAN-bus equipped BMW Motorcycles.
