Can you measure the internal resistance of a battery?

Yes, you can measure the internal resistance of any type of battery using the same method. However, keep in mind that the internal resistance may vary depending on the battery chemistry and its state of charge. What precautions should I take when measuring the internal resistance of a battery?

How do you know if a battery has internal resistance?

The most common method for determining a battery’s internal resistance is to connect it to a circuit with a resistor, measure voltage through the battery, calculate current, measure voltage through the resistor, find the voltage drop, and use Kirchhoff laws to determine the remaining resistance, which is internal resistance.

What is 'internal resistance' in a battery meter?

Load current flows from the battery (under test) through the meter leads en route to the load resistance (inside the meter) so the value of ‘internal resistance’ obtained will be the sum of lead resistance and battery internal resistance.

What does a low internal resistance battery mean?

Here are some guidelines: A low internal resistance indicates a healthy battery with good power delivery capabilities. A high internal resistance suggests potential issues such as aging, degradation, or cell damage. Comparing the internal resistance values with manufacturer specifications or similar batteries can provide additional insights.

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.

Can a battery deliver high starting current with low internal resistance?

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.
