Frequently Asked Questions

What is the internal resistance of a battery?

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.

Where can I find battery internal resistance and short circuit current values?

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.

What is the value of internal resistance in a practical circuit?

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.
