How to test batteries?

[FNG]

I just bought 50 Rayovacs from Ebay and was wondering how to test them? I have a DVOM that works pretty good. I read that people here use real battery testers but ive never seen them. What do they look like? What should the voltage be on my batteries for it to be good?
