BATTERIES             
                                          
 BATTERIES  MAY  NOT  HARM  A  HUMAN  OR, 
 THROUGH  INACTION,  ALLOW A HUMAN  BEING 
             TO COME TO HARM.             
                                          
 A BATTERY MUST  OBEY THE ORDERS GIVEN IT 
 BY   HUMAN   BEINGS  EXCEPT  WHERE  SUCH 
 ORDERS  CONFLICT  WITH  THE  FIRST  LAW. 
                                          
 A   BATTERY   MUST   PROTECT   ITS   OWN 
 EXISTENCE AS  LONG  AS  SUCH  PROTECTION 
 DOES  NOT  CONFLICT WITH  THE  FIRST  OR 
               SECOND LAWS.               
                                          
                                      
                                          
  THESE THINGS POWER ALMOST EVERYTHING,   
 BUT  WHEN  I  SPEAK  ABOUT  BATTERIES  I 
   SPEAK ABOUT STANDARD HOUSEHOLD ONES.   
         THINK DOUBLE A, TRIPLE A,        
    TWENTYFIVE TWENTY, NINE VOLT, SUCH    
                 THINGS...                
                                          
 THEY  LOOK  SLICK  BUT  ARE  VERY  DIRTY 
                 INSIDE.
