I was going to recommend this same tester. What is cool about it is that you can fully charge a battery, then set this up to the proper discharge rate, and terminal voltage (from the battery datasheet), and let it run. It will automatically terminate at the correct discharge voltage and tell you the total capacity of the battery.
It's slow enough you wouldn't want to do it in the field, but it definitely would work if you swapped the batteries, brought them into the shop for testing/maintenance.
