Lead acid batteries typically have an internal resistance around 20 milliohms. Thanks Crosstalk for replying me. You said 20 mOhms for a typical lead acid battery. But what is the typical ? 20, 40 or 100Ah ? (12V). I'm not 100% sure on this, but I don't think that the battery's capacity matters.
For a lead-acid battery cell, the internal resistance may be in the range of a few hundred mΩ to a few thousand mΩ. For example, a deep-cycle lead-acid battery designed for use in an electric vehicle may have an internal resistance of around 500 mΩ, while a high-rate discharge lead-acid battery may have an internal resistance of around 1000 mΩ.
The resistance of modern lead acid and lithium-ion batteries stays flat through most of the service life. Better electrolyte additives have reduced internal corrosion issues that affect the resistance. This corrosion is also known as parasitic reactions on the electrolyte and electrodes.
The battery internal resistance tester is a measuring instrument used to measure the internal resistance, voltage, and temperature of rechargeable batteries such as lead-acid batteries and lithium batteries to judge the health status of the battery. It can also be used as an instrument to measure the ESR parameters of electrolytic capacitors.
Measuring the internal resistance of a battery cell can be useful for determining the performance of the cell and identifying any issues that may affect its performance. For a lithium-ion battery cell, the internal resistance may be in the range of a few mΩ to a few hundred mΩ, depending on the cell type and design.
The overall battery resistance consists of ohmic resistance, as well as inductive and capacitive reactance. The diagram and electrical values differ for every battery. Measuring the battery by resistance is almost as old as the battery itself and several methods have developed over time, all of which are still in use.
