Comparison chart -
The chart below shows the discharge curve for two AA
Alkaline brands. The X-axis has a different value, but one can calculate the Discharge Capacity in percent, by dividing the X-axis value by the battery's rating.
Astute observers will see additional differences between the two graphs. The NiMH chart above seems to assume users live in a very cold refrigerator. I guess we could read our JBLs by the refrigerator light, but some gnome is supposed to turn it OFF when the door is closed
Conclusion:
Other than noting average operating voltage, I'm not going to make one.
