I'm reading an old thread over at CPF about a guy who unknowingly mixed a pair of CR123 batteries where one had a different voltage than the other. The batteries exploded and he was left with HF damage of the lungs.
Not to freak anyone out, and I know many of us know not to mix new and old batteries, but in my gear the Steripen is the only thing that uses a pair of CR123 batteries. Might be worth calling attention to in this forum (to make sure your batteries are the same).
