Internal resistance in a battery refers to the amount of resistance that the battery's internal components, such as electrodes, electrolyte, and terminals, present to the flow of current within the battery. This resistance causes some of the electrical energy produced by the battery to be converted into heat, reducing
The lower the internal resistance, the better. A battery with normal internal resistance can be charged at higher currents with less heat. In half the cases, a battery with low resistance is capable of delivering a high cold cranking current. The internal resistance cannot accurately determine the battery capacity.
Not every battery is capable of delivering high starting current with low internal resistance. Only in half of the cases is the assessment of the remaining battery life based on internal resistance correct.
This resistance causes some of the electrical energy produced by the battery to be converted into heat, reducing the amount of available voltage and current that can be delivered to an external circuit. The internal resistance of a battery can be calculated by measuring the voltage drop that occurs when a known current is drawn from the battery.
If the internal resistance of the battery cell is not provided by the manufacturer, as we’ll see in this article, using the discharge characteristics of the battery cell, we can calculate the internal resistance of the battery cell, for a specific state of charge value.
Current equals voltage divided by resistance (i=v/r). So the higher the internal resistance, the lower the current output ability. Low internal resistance batteries are much better at supplying high current pulses. Internal resistance also increases as the battery discharges.
