Measuring Internal Resistance of Batteries
NOTE: We can only take a snapshot of the internal resistance with this method. The internal resistance can vary with things like battery age and temperature. In 10 minutes, the resistance value might be different! A common AA alkaline battery might have anywhere between 0.1 Ω and 0.9 Ω internal resistance.
Battery Internal Resistance
Current equals voltage divided by resistance (i=v/r). So the higher the internal resistance, the lower the current output ability. Low internal resistance batteries are much better at supplying high current pulses. Internal resistance also increases as the battery discharges. Therefore, a typical alkaline AA battery may start out with an ...
