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.
For example, a good internal resistance for a lead-acid battery is around 5 milliohms, while a lithium-ion battery’s resistance should be under 150 milliohms. What is the average internal resistance of a battery? The average internal resistance of a battery varies depending on the type and size of the battery.
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.
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 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 normal internal resistance of a 12v battery can vary depending on the type and age of the battery. However, a healthy 12v lead-acid battery should have an internal resistance of around 3-5 milliohms. What is the internal resistance of a bad battery? A bad battery will have a significantly higher internal resistance than a healthy battery.

Internal resistance is important in lead batteries because it can affect the voltage and current output of the battery. High internal resistance can lead to voltage drops and reduced capacity, while low internal resistance can improve the battery''s performance and efficiency.
PVsyst provides a default value based on a reasonable voltage drop at a given current. For lead-acid batteries, this default is 40 mV at C10. For Li-Ion, this is much less, 16 mV at C10. This low value allows to use Li-Ion batteries at very high charge/discharge rates without prohibitive heating.

In summary, the approximate internal resistance of a typical lead acid battery, such as a 12V 20Ah battery, is around 20 milliohms. However, this may vary depending on the battery''s construction and age, as well as factors such as state of charge and type of battery (AGM vs gel). Higher capacity batteries may have lower internal resistance due to larger …
