Although batteries’ internal resistance would ideally be zero, internal resistance exists due to a variety of factors. Internal resistance increases as a battery degrades. On battery cell production lines, defective cells are detected by comparing the internal resistance of tested cells to that of known-good reference cells.

When measuring the internal resistance of a battery cell using the AC method, an AC resistance meter specifically designed to measure low resistance levels (i.e., a battery tester) is used. AC resistance meters apply a constant-current AC signal to the battery. They then detect the minuscule voltage generated by the current and calculate the
What is the typical internal resistance of a lithium-ion battery? The typical internal resistance of a lithium-ion battery varies depending on its capacity and design. Generally, it ranges from a few milliohms to tens of milliohms. For example, a 2000 mAh lithium-ion battery may have an internal resistance of around 50-100 mΩ.
