Simple, you measure the voltage of the battery, while the battery is
installed in the circuit where you intend to use it. In our case,
this means measure the voltage of the 1/2AA while it is installed in
the computer and the computer is unplugged. If it is significantly
below 3.6V, then it can no longer deliver the current that the
computer needs, while maintaining an acceptable voltage level.
In other words, measure the voltage of the source while the source is
under the intended load.
For the nitpickers, okay, that's not a method of measuring amperage,
but it is a proper test of a PRAM/NVRAM battery.
