*1 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.
*2 Current value is determined so that 50% of the nominal capacity is obtained with an end
voltage of 2.0V at 23 oC.
*3 Current value for obtaining 0.8V cell voltage when 15sec. pulse is applied at 50%
discharge depth at 23 oC.
*
ML414RU is capable of reflow soldering. Consult with FDK about the reflow condition.
