ULCS offers this Pulse Load Battery Tester. I've found it to be very helpful in determining bad or low capacity cells. It's listed under "What's New" at the bottom of their web page.

Advantage of Pulse Load Technology
Battery performance is very important in today’s electronic
devices. The Mini-MBT computes the battery’s
actual remaining power capacity using a 2-second pulse
load test. This pulse load simulates the real power
demand that batteries experience during normal operation.
So battery performance is measured, not just
voltage or internal resistance. The load is automatically
disconnected, so testing will not harm or drain
the battery.
Testing capability: 1.2v NiMH rechargeable [AA, AAA, C, D]
1.2v NiCd rechargeable [AA, AAA, C, D]
1.5v alkaline [AA, AAA, C, D, N]
3v photo lithium [CR123, CR2, CRV3]
9v alkaline, carbon zinc
Display: Five (5) LEDs - Green, yellow, and red
Contact terminals: Nickel-plated brass. Positive terminals fixed. Built-in
negative test lead.
Dimensions: 4 x 2.5 x 0.75 in.
Weight: approx. 3 oz. (85g)
Part No.: Mini-MBT
