3.2 Battery Internal Resistance
Battery internal resistance is a nonlinear parameter that changes with changes in battery
temperature and discharge state. The internal resistance is lowest when the battery is fully
charged. At full charge and 25°C the internal resistances and short circuit currents are as
follows:
Table 3-1, General Specifi cations
Model Internal Resistance (m Ω) Short Circuit Current (A)
SMU 2-200-FR 0.514 3940
SMU 2-300-FR 0.363 5588
SMU 2-400-FR 0.297 6816
SMU2 -500-FR 0.218 9361
SMU 2-600-FR 0.175 11576
SMU 2-800-FR 0.223 9153
SMU 2-1000-FR 0.189 10804
SMU 2-1500-FR 0.152 13237
SMU 2-2000-FR 0.115 17391
Table 3-2, Internal Resistance and Short Circuit Current (25°C)
A short circuit will drop the battery voltage to zero and physically damage its internal components,
poles, and connectors.
