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.
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.
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.
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.
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.
For a nickel-metal-hydride (NiMH) battery cell, the internal resistance may be in the range of a few hundred mΩ to a few thousand mΩ.
