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.
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.
Measuring a battery voltage without any load with a voltmeter starts the process of calculating its internal resistance. Then, connect a load with known resistance across the battery and track the voltage once more. Having gotten these readings, you should do some paperwork. There are several ways to measure a battery’s internal resistance.
What you need: How to find internal resistance of a battery using this method: Inject a known pulse of current into the battery. Observe the voltage drop using the oscilloscope. Use the relationship between voltage drop and current to calculate internal resistance.
