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.
