2. Internal resistance and short circuit current
The internal resistance of the battery is a dy
d along with the temperature and discharge state. The internal resistance is the lowest
when battery is fully charged. The table 2-1 shows the internal resistance and short circuit
current in fully charged state according to the IEC60896 standard.
