The Auto Charge D is a dual battery system automatic battery charger designed especially for vehicles with a DDEC engine control and a separate engine battery. These vehicles have a unique problem. The vehicle may have a number of batteries connected in parallel in order to obtain sufficient capacity for the electrical loads. The engine usually has only a single battery, isolated from the vehicle battery and dedicated to powering the engine electronic controls. This configuration requires complete isolation between the chargers and automatic charging of both batteries. Also, a high capacity charger is required for the vehicle while only a small amount of charge is required to maintain the engine battery.
A dual bargraph display is provided to indicate the state of charge of each battery. The display is conveniently labeled “VEHICLE” and “ENGINE” battery.
A 5 ampere "Battery Saver" is provided to power rechargeable handlights or other accessories. The "Battery Saver" automatically disconnects these accessory loads from the battery and powers them from an internal power supply. This removes the accessory loads from the battery during charging.
