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.
