This method involves injecting a small AC signal into the battery and measuring its voltage response. The internal resistance is derived by calculating the ratio of voltage to current. This method provides high accuracy and is gentle on the battery. It works well for measuring resistance without causing significant impact on the battery's state.
When the battery draws current to supply a load, this introduces a small voltage drop which would not be there if the voltmeter were connected directly to the battery's positive and negative terminals. On one of the two meters used for this experiment, there is a “battery test” setting for either 1.5-volt or 9-volt batteries.
