6 FAQs about [Measure the resistance wire of lead-acid battery]

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.

Where should a battery voltage be measured?

In practice the lead resistance and contact resistance could add to the reading, which is why they tell you to measure the voltage directly at the battery terminals not at the clips or at the circuit. This is a type of 4-wire AC resistance measurement, and is vitally important if you want accurate readings of low resistances.

How to test a battery resistor?

make the period of connection of battery and the resistor as short as possible - use a reasonable value of resistance, 10ohm should be sufficient for all kind of test. Even thought the value of the resistance is printed, you still need to confirm whether the actual resistance is the same as shown.

Why are lead acid and lithium ion batteries resistant?

The resistance of modern lead acid and lithium-ion batteries stays flat through most of the service life. Better electrolyte additives have reduced internal corrosion issues that affect the resistance. This corrosion is also known as parasitic reactions on the electrolyte and electrodes.

How do you measure a battery?

Measuring the battery by resistance is almost as old as the battery itself and several methods have developed over time, all of which are still in use. The ohmic measurement is one of the oldest and most reliable test methods. The battery receives a brief discharge for a second or longer.
