BATTERIES (ELECTRIC POWER DISTRIBUTION)
 
     
 
NOTE
  
     
          Batteries other than the main storage batteries are not employed for electric power distribution in German submarines.  
          Dry cells are used for various purposes such as portable radio receivers, flash lights, etc.  These cells are simpler in shape, size, and design to those available commercially in U.S.  Voltages observed are 1, 5, 3, 6, 45, 90 and 120.  
          Wet cell batteries are used in the following circuits:  
          (1)  The resistance thermometer with the main motor bearing temperatures.  This battery is a six volt battery designed and constructed much the same as U.S. automobile batteries.  
          (2)  The emergency lighting circuit employs a 4.5 volt wet cell at each lighting fixture.  Several of these cells have been sent to BuShips, Code 660 for detailed exploitation, and reference should be made to their report when it becomes available.  
          A small constant potential battery charging panel is installed for charging the above batteries.  There is nothing unique in its construction or design.  This panel is also used for charging torpedo batteries which have been removed from the torpedo thus serving as a standby
