Thanks Luke. My brain hates you but I think its slowly sinking in. So since I already have the 2.5v zeners, should I return them or just add a 50-ish ohm resistor in series to each one?

That would be a bad idea in this instance since each cell is only rated to a maximum of 2.7v. Hook up a 12v source on a single cell and there's going to be a very loud pop.
