How to check if Film Camera battery works?

I found 6-7 film camera batteries and some of them are finished while some may work, and I've tried about a billion combinations and none of them are working. Is there anyway to check if the battery works without a voltage meter or those gizmos that measure battery life?

But, the cost of the tester would buy new batteries several times. The economics of the situation does not favor the tester investor.

Put battery in the camera. Turn camera on. If camera works; battery good. If not; battery no good.

You could use the testers you mentioned.

aw i was hoping you could do some sort of easy scientific experiment, like dipping the batteries in vegetable oil and if it turns red it means it still works or something...

Unfortunately, camera batteries are too weak for the more... household-type "experiments"

If you have another device that uses the same type # battery, then you could try them in that item to see if they will power it.
If they are not expensive batteries, you could buy enough of the least expensive ones to power the camera. If the camera works, then you can use the camera to test the ones you have.
If the camera takes two similar batteries, then you only need one to check the others. Put the new one in the camera, then try it in combination with each of the questionable ones.
