The lead-acid battery internal resistance model established by PNGV are all simulated in (Wei et al. 2009); the real-time identification can be carried out by the BP algorithm.
To elucidate the deterioration mechanism of valve regulated lead-acid battery (VRLA) under high-rate partial-state-of-charge (HRPSoC) duty, the cyclic performance and the direct-current internal resistance (DCIR) of VRLA with addition of a granular carbon additive, (Vulcan 72, VC 72) in the negative active materials (NAMs) are investigated specifically.
Internal resistance or impedance measurements are a common method to assume the condition of a lead-acid battery. The readings could lead to predictions about the state-of-charge (SoC) and/or state-of-health (SoH) condition of a battery without the necessity of performing a full charge/discharge cycle. In practice, the readings

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.
Power-Sonic batteries use state of the art design, high grade materials, and a carefully controlled plate-making process to provide excellent output per cell. The high energy density results in superior power/volume and power/weight ratios. High Discharge Rate Low internal resistance allows dischar ge currents of up to

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.
Changes hidden within the batteries’ opaque case material can be identified by their corresponding affect on the internal resistance of a cell. As battery cells age and deteriorate, the internal resistance values in the cells increase, indicating a departure from healthy battery readings.
There were variations in the internal ohmic readings that were unrelated to the test variables. Based on the preliminary results of this study, it is recommended that internal ohmic readings not be used as the sole acceptance criteria for lead-acid batteries.
Over the past 30 years, internal resistance testing has become the standard for monitoring the characteristics of VRLA battery performance. Changes hidden within the batteries’ opaque case material can be identified by their corresponding affect on the internal resistance of a cell.
Lead-acid batteries naturally degrade as they age. One effect of this deterioration is the increase in resistance of the various paths of conductance of the internal cell element. The internal ohmic test units are generally designed to detect this internal change.
