[Elecraft] Calibration Standard

[Stephen W. Kercel]

The ARRL Handbook says that a cheap way to get a voltage calibration 
standard is to use a brand new D cell. It is supposed to have a voltage of 
1.56 Volts. Assuming that one wanted to use a set of D cells as a voltage 
standard (say for checking a DMM), is there a way to store them to minimize 
the rate at which the voltage runs down? Can one store them in a 
refrigerator or freezer? Does it do any harm? Does it do any good?
