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.
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.
A fully charged lead-acid battery should have a voltage of around 12.8 volts. If the voltage drops below 12.4 volts, the battery needs to be recharged. Internal resistance is also an important factor to consider. A battery with high internal resistance will have difficulty delivering power, which can result in poor performance.
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.
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 example, a high-capacity NiMH battery cell designed for use in an electric vehicle may have an internal resistance of around 1000 mΩ, while a high-rate discharge NiMH battery may have an internal resistance of around 2000 mΩ.
