Much research on battery internal resistance has been carried out to improve the accuracy of battery SOC estimation and the reliability of battery. As we know, lead-acid battery resistance is divided into three parts: ohmic resistance, electrochemical resistance, and concentration polarization resistance.
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.
One of the most important properties of lead–acid batteries is the capacity or the amount of energy stored in a battery (Ah). This is an important property for batteries used in stationary applications, for example, in photovoltaic systems as well as for automotive applications as the main power supply.

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.
Another important performance factor for lead–acid batteries is self-discharge, a gradual reduction in the state of charge of a battery during storage or standby. The self-discharge takes place because of the tendency of battery reactions to proceed toward the discharged state, in the direction of exothermic change or toward the equilibrium.
Each of the different phenomena itself may depend on the battery state (SoC and temperature), load (current) and short-term history (length of rest period, charging and discharging). The observed internal resistance strongly depends on the applied measurement technique.
