The battery internal resistance tester is a measuring instrument used to measure the internal resistance, voltage, and temperature of rechargeable batteries such as lead-acid batteries and lithium batteries to judge the health status of the battery. It can also be used as an instrument to measure the ESR parameters of electrolytic capacitors.
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.
Since the internal resistance of sealed lead-acid batteries tends to increase sharply as deterioration progresses (1.5- to 2-fold increase from the initial value), the state of batteries can be determined by monitoring the trends in the data.
This measurement technique requires that the battery voltage is measured for two short discharges for a specified period with a 5-minute resting period in between. The first discharge produces V 1 using I 1 and the second V2 using I2. The formula for Internal Resistance is Measurement sequence:
To take a measurement a change in voltage has to occur on the battery. This change can be induced by the test equipment or the power system itself. The measurement value of a battery is dependent on the rate of change and amplitude of the stimulus applied. That is why different battery testers may produce different readings for the same battery.
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.
BU-902: How to Measure Internal Resistance
The internal resistance provides valuable information about a battery as high reading hints at end-of-life. This is especially true with nickel-based systems. Resistance measurement is not the only performance indicator as the value between batches of lead acid batteries can vary by 5–10 percent, especially with stationary units. Because of ...
