In this article, we will show you how to measure internal resistance of a battery. Battery Internal Resistance. A battery is considered as a perfect voltage source with an impedance known as internal resistance linked in series. When the battery is operational, the output voltage is less than the open-circuit voltage (termed as OCV).
Lead-acid batteries have a very small internal resistance (typically 0.01 ohms) — that is why they are capable of supplying the high current necessary to start the engine. The internal resistance of lead-acid cells is so small because there are several negative and positive plates in each cell connected in parallel. Also, the distance between ...
