4. Internal resistance and short circuit current
The internal resistance of the battery is a dynamic nonlinear parameter that is
continuously changed along with the temperature and discharge state. The internal
resistance is the lowest when battery is fully charged. The table 2-4 shows the internal
resistance and short circuit current of Narada battery in fully charged state according
to the IEC60896-21/22 standard.
