I second this. I've got this charger and a number of various
brands/capacities of NiMH AA's. The charger does each cell individually,
can discharge, and measures the actual capacity of batteries by measuring
the total current that can be squeezed out of it during a discharge cycle.
Well worth the money. Every 6 months or so when I go home, I cycle my
family's AA's through it. They always need some help as the cheap
chargers charge in pairs and eventually some get less than others. I've
even matched sets of 4 AA's with the same *measured* capacity for use
together in cameras, flashes, etc. Better on the batteries (since they
all discharge together) and much longer life.
Also, the comments about building discharge rigs are not a good
idea for battery life unless you discharge each cell independently. If
you run a stack of 2 or 4 into a flashlight or something, whichever cell
dies first gets reverse-voltaged as the other continue to force current
through it. Badness.
