How to measure internal resistance of a battery?

One can mention the IEC 61960 standard or PNGV (Partnership for a New Generation of Vehicles) procedure for example. Measurement methods for the internal resistance of batteries can be divided up into two categories: DC (Direct Current) techniques and AC (Alternating Current) techniques.

What is the internal resistance of a battery?

The internal resistance of a battery is the resistance that the battery offers to the electrical current flowing through it. The lower it is, the better. Schematically, it can be represented as an EMF source with a resistor connected in series to it. This is shown in the picture below.

What is internal resistance testing?

Over the past 30 years, internal resistance testing has become the standard for monitoring the characteristics of VRLA battery performance. Changes hidden within the batteries’ opaque case material can be identified by their corresponding affect on the internal resistance of a cell.

Can a ohmmeter measure the internal resistance of a battery?

The internal resistance of a battery cannot be measured with a simple ohmmeter. The measurement requires a special device or voltmeter with a known load. Overall, the internal resistance of a battery is an important and useful characteristic.

What is the internal resistance of a 12V battery?

The normal internal resistance of a 12v battery can vary depending on the type and age of the battery. However, a healthy 12v lead-acid battery should have an internal resistance of around 3-5 milliohms. What is the internal resistance of a bad battery? A bad battery will have a significantly higher internal resistance than a healthy battery.
