Charge Performance Curve; Internal Resistance And Short Circuit Current - Narada 12NDT26 Operation Manual

3. Charge Performance Curve

Fig.2-2 is the battery voltage vs charge time curves at 25° C

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.
