Dimensions
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.
