                                    FIGURE 9.16  Zinc-carbon batteries, discharged under simulated cassette application (10 ohm intermit-
                                    tent load) at 20°C.


                                using an intermittent discharge since it assists in dissipating reaction product barriers and increases
                                service life. Zinc chloride batteries would show less evidence of an effect because of their improved
                                transport characteristic.
                                   Figure 9.16 shows the same four battery sizes discharged through a relatively low resistance of
                                10 ohms (about 150 mA) on a simulated intermittent cassette application. AAA- and AA-size batter-
                                ies deliver about 30% less service when continuously discharged at this load.
                                   The relative performance of both Leclanché and zinc chloride AAA, AA, C, and D batteries
                                roughly follows a 1:2:8:16 proportion to the 0.9 V cutoff for the low rate and a 1:2:12:24 proportion
