I know there was a whole thread already regarding replacing 2 cr2016s w a single 2032, but I still have a question. Is the problem with that decreased performance of the device? Destruction of the device? Are electric devices as sensitive as electronics? I just popped a 2032 into a dog collar light that's made to run on two 2016s. It works. Is it going to glow less brightly, burn out faster, is the whole thing going to explode, or what? Also, does the fact that this thing has a flash mode make it electronic? Thanks for sharing your wisdom.
