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.
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.
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.
References: Shukla et al. 1998. Rodrigues et al. 1999. The internal resistance of lithium-ion is fairly flat from empty to full charge. The battery decreases asymptotically from 270 mW at 0% to 250 mW at 70% state-of-charge. The largest changes occur between 0% and 30% SoC. The resistance of lead acid goes up with discharge.
Consider a standard AA alkaline cell. When fresh, it might exhibit an internal resistance of about 0.150 Ω. However, as the battery ages or is subjected to adverse conditions, this value can rise to 0.273 Ω or even higher. This change in internal resistance can significantly affect the battery’s performance.
