Why is it Important to Measure Battery''s Internal Resistance?

Internal Resistance principles

"Two methods are used to read the internal resistance of a battery: Direct current (DC) by measuring the voltage drop at a given current, and alternating current (AC), which takes reactance into account. When measuring a reactive device such as a battery, the resistance values vary greatly between the DC and AC test methods, but neither reading is right or wrong.

How to Measure Internal Resistance of a Battery

The open circuit voltage of the battery can also be measured and the voltage drop (under load) can hence be calculated. Dividing this voltage drop by circuit current yields internal resistance. A note on the load resistor value of 30.5 ohms is that it was probably carefully chosen as being representative of a "mid-range" AA battery load
