9.24 PRIMARY BATTERIES

FIGURE 9.20 Comparison of Leclanché and zinc chloride D-size batteries of various grades continuously discharged
through 3.9 ohm at 20°C. GP: General purpose; HD: Heavy duty; EHD: Extra heavy duty.

FIGURE 9.21 Comparison of Leclanché and zinc chloride D-size batteries of various grades discharged on a simu-
lated cassette application, 3.9 ohms, 1 h/day at 20°C. GP: General purpose; HD: Heavy duty; EHD: Extra heavy duty.

battery, for the same testing, is shown in Fig. 9.23b. Figures 9.24a and b present the same perfor-
mance relationships except for both the Leclanché and zinc chloride batteries in the heavy-duty
D-size battery and Fig. 9.25 for the zinc chloride extra/super heavy-duty battery.
Performance differences between the batteries of the same grade but from different manufactur-
ers are shown in Fig. 9.26. There is a difference of about 25% between the best and poorest battery
to the 0.9 V cutoff.
