Nominal capacity is determined to an end voltage of 2.0V when the battery is allowed to  
discharge at a standard current level at 23oC.  
*1  
Current value is determined so that 50% of the nominal capacity is obtained with an end  
voltage of 2.0V at 23 oC.  
*2  
*3  
Current value for obtaining 2.0V cell voltage when 15sec. pulse is applied at 50%  
discharge depth at 23 oC.
