Why Does Drax Call Anulax Batteries As Harbulary Batteries?

Drax calls them Harbulary batteries because he overestimates himself a lot. He overvalues his significant strength and considers himself invisible because he can stand still for a long time. It might be possible that he thinks of himself as more competent than Peter Quill and thinks Quill is a fool who calls Harbulary batteries as Anulax batteries.
