How many is enough?
Spyderman is correct- the wrong battery voltage will throw your exposures off in a non-linear way. IOW- each shot's exposure could be off a different amount depending on the lighting. Either use it on manual, or if you do use the wrong battery just use negative film, not slide film to test the camera. Negative film should handle 3 stops error no problem.
I've used the Olympus OM system for approx 30 years. Be careful, these cameras and lenses are addicting. Just yesterday I went thru my OM body and lens collection with the intention of selling them to finance more Leica RF gear purchases, and I just couldn't do it. I decided to keep them and use them more.
