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. Can high internal resistance cause a battery to fail?
Generally, a lower internal resistance indicates a healthier battery. For example, a good internal resistance for a lead-acid battery is around 5 milliohms, while a lithium-ion battery’s resistance should be under 150 milliohms. One way to measure internal resistance is by using the open-circuit voltage method.
This process also increases the internal resistance of the battery, reducing its other characteristics. What should the internal resistance of the battery be? The normal internal resistance of a properly charged car battery with liquid electrolyte is in the range of 4-6 mOhm. For AGM it is lower due to a specific device - 3-4 mOhm.
Batteries will always have some resistance. Though the internal resistance may be or appear low, around 0.1Ω for an AA alkaline battery, and about 1Ω to 2Ω for a 9-volt alkaline battery, it can cause a noticeable drop in output voltage if a low-resistance load is attached to it.
Consider a standard AA alkaline cell. When fresh, it might exhibit an internal resistance of about 0.150 Ω. However, as the battery ages or is subjected to adverse conditions, this value can rise to 0.273 Ω or even higher. This change in internal resistance can significantly affect the battery’s performance.
One approach to calculating internal resistance involves the voltage drop method. Start by measuring the open-circuit voltage of the battery. Then, apply a known load (a resistor or device with a general resistance) to draw current from the battery. Measure the voltage across the battery terminals while the load is connected and drawing current.
