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.
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.
Lead acid has a very low internal resistance and the battery responds well to high current bursts that last for a few seconds. Due to inherent sluggishness, however, lead acid does not perform well on a sustained high current discharge; the battery soon gets tired and needs a rest to recover.
Generally, a lower internal resistance indicates a healthier battery. 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. One way to measure internal resistance is by using the open-circuit voltage method.
If the internal resistance increases on one of the battery cells this means the battery will supply less current and will probably heat up more than it should. There is a direct connection between the battery internal resistance and the C-rating of the battery pack. Typically the high C-rating batteries have lower internal resistance values.
Factors affecting a battery’s ability to act as an ideal voltage source include: Age of the battery: Older batteries tend to have higher internal resistance. Temperature: Extreme temperatures can affect the internal chemistry, leading to increased resistance. State of charge: A battery’s internal resistance can vary depending on its charge level.
