6 FAQs about [Lead-acid battery DC internal resistance test]

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.

Does resistance reveal the state of health of a battery?

Resistance does not reveal the state-of-health of a battery and often stays flat with use and aging. Cycle test on Li-ion batteries at 1C: What Is Impedance?

What ohm test does a battery use?

The 1,000-hertz (Hz) ohm test is another common method. A 1,000Hz signal excites the battery and Ohm’s law calculates the resistance. Note that the AC method shows different values to the DC method when measuring a reactive resistance, and both readings are correct.

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.

What is battery resistance?

The overall battery resistance consists of ohmic resistance, as well as inductive and capacitive reactance. The diagram and electrical values differ for every 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.

How accurate is a DC load test?

DC load measurements work well to check large stationary batteries, and the ohmic readings of the device are very accurate and repeatable. High-end test instruments claim resistance readings in the 10 micro-ohm range.
