Higher cranking amperage... diesels can take a bit more effort to start, especially in cold weather. Two is common for light duty vehicles.. medium- and heavy duty trucks often use four.
being a super duty i assume this is a diesel engine. diesel trucks have 2 batteries. did you check both batteries. then check all fuses if it is a diesel engine there will be 2 batteries .did you check both batteries

I don't think there is such a thing as a "diesel battery". Perhaps you mean the batteries used in diesel cars; the batteries usually used in cars are lead-acid batteries, the acid being sulphuric acid.
Most diesels have 2 batteries to supply the necessary cold cranking amps Two little batteries are cheaper then one big battery
An F350 diesel will have them both under the hood, towards the front of the engine, with one on either side of the engine. The two batteries wired in parallel gives greater cranking amperage.
Optima Batteries RedTop
It was built with two batteries, yes.
According to the 2004 Ford F-250 Diesel Supplement : It came from the factory with ( 2 ) ( Motorcraft BXT-65-750 batteries ) * that's BCI group size 65 , 750 cold cranking amps
They were powered by diesel engines and batteries. The batteries were for underwater use and the diesels propelled the sub and charged the batteries while running on the surface.
with tools
The batteries will have to be connected in parallel. Connect both positive posts to the starter solenoid and both negative posts to the frame.
because diesel are very high compresion, it takes alot more cranking power for a diesel that a gas motor
