Internal resistance is the amount of opposition that is caused by the flow of current. It is offered by the cells and batteries as a response to the current flowing in them. The internal resistance of the battery is measured in Ohms.
Battery Internal Resistance & Short Circuit Current. Battery Internal Resistance & Short Circuit Current. Battery internal resistance and short circuit current values are available from battery manufacturers.
The value of internal resistance may be used to estimate the short circuit current in a practical circuit. Consider a 250 Ah cell having a published internal resistance of 0.33mΩ. The battery has a total of 24 cells connected in series giving a total cell resistance of 0.33 x 24 = 7.92mΩ. The external circuit has an estimated resistance of 0.5 mΩ.
