     Not that I know of, you would have to solder the wires onto   
   the connection prongs using a AC adapter that you can get   
   from radio shack.   
       If you know some one handy enough, you could have wooden   
     dowels cut to the same size of the batteries and place them   
     in the slots to fill up the void, on one end of the dowels   
   you would need to put a brass screw in the end where you   
   can connect the AC adapter lead to.   
      Make sure you get the polarity correct.   
      
      since you're using 3 D cells, that would be 3 x 1.5 volts =   
     4.5/   
     you can use a 5 Volt DC adapter at around 500 ma's or better.
