The total opposition that a battery offers to the flow of 
alternating current. Impedance is a combination of resistance 
and reactance.

The typical impedance of these cells on open circuit and during 
useful discharge varies from 5-20 ohms. This applies over a 
frequency range of 40-5,000 hertz at the current drains shown 
below.
