One easy way to do this is to set your volt meter on the
highest amperage (10+ amps) range, and put the test leads
directly across a single cell (don't try this with
C or D cells!!!!).

I wouldn't try it with AAA's or AA's either, unless you fancy changing the
fuse in your multimeter.

Compare the amperage reading of each
of the cells, and it will be obvious which one is bad.

Comparing the voltage is an even easier way, and less likely to end up
frying your meter leads when you discover your multimeter isn't fused on the
top range.
