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.
