⚡ Battery internal resistance: what is it and how to measure it?
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. After 4 years of operation, this parameter may increase to 13-15 mOhm.

I am making a battery tester, for lithium ion batteries in particular. I want to measure the internal resistance, but after testing few cells, I am skeptical of my results. Most of them, new or old are around 500-800 mOhm, totally not close to 150 mOhm range as it should be.
When to Retire/Dispose LiPo Battery?
Even if you don''t abuse your battery, the normal everyday use of your battery will generate gas through a process called electrolyte decomposition. ... e.g. 3.55V, 3.59V, 3.61V. The point being, they should all be within reasonable range. When the internal resistance of particular cells are wildly higher than the rest, the voltage always …
Battery Internal Resistance
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 …
What is Internal Resistance (IR) and how to test battery resistance
A battery can be regarded as an ideal voltage source in series with an impedance, which is called internal resistance. When the battery works, the voltage output is lower than the open-circuit voltage (abbreviated as OCV). The difference is the voltage drop caused by the internal resistance. The internal resistance is measured by ohm (Ω).
Battery Internal Resistance
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 ...
