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  
*2 Current value is determined to be the level at which 50% of the nominal  
capacity is obtained with an end voltage of 2.0V at 23 oC.  
Current value for obtaining 2.0V cell voltage when pulse is applied for  
15seconds at 50% discharge depth at 23 oC.
