When measuring resistance, a small known current, usually in the microampere (µA) range, passes from the tester''s battery through the component under test. When the
The internal resistance of the battery is very small when it leaves the factory, but after long-term charging and discharging, due to the loss of the electrolyte inside the battery
Resistance is a fundamental concept in electrical and electronics engineering, varying from the very low (like in transformer winding) to very high (such as the insulation resistance of those same windings). Although
The pulse load test is another method for measuring battery internal resistance. It involves applying a short-duration, high-current pulse to the battery and measuring the voltage response. The internal resistance can be calculated from the voltage drop during the pulse. 1.
Ideally, a battery's internal resistance should be zero, allowing for maximum current flow without any energy loss. In reality, however, as illustrated in Fig.1, internal resistance is always present. Let's consider an example to illustrate this. The battery voltage is determined by the internal resistance and the output current.
The first reason for measuring internal resistance is to ensure quality control throughout production. It is possible to determine the quality of a battery by measuring its internal resistance. However, how many ohms of internal resistance would be considered a high-quality battery? Well, it depends on the type of battery.
The internal resistance cannot accurately determine the battery capacity. There are also such testers, but you should not blindly trust their readings, since they do not measure the real capacity, but only calculate it. Not every battery is capable of delivering high starting current with low internal resistance.
The internal resistance of a battery is an important parameter for quality inspection during production and maintenance process. Get the best performance out of your battery by measuring it properly. The internal resistance of a battery can be used for two different purposes.
