You can test the voltage with a multimeter, or some batteries you buy come with an inbuilt tester. Failing that get a torch globe and a piece of wire. Wrap the wire around the globe, place the globe on the + end of the battery and the end of the wire on the - end, and see which lights brighter.

Da, sounds like you may need to take them all to RadioShack and see if someone will test them for you.
They do make testers for batterys.
