Bottom Line

If you’re looking for a dependable battery for your old 35mm film camera or certain sensors, the Energizer 123 Lithium Photo Batteries can do the job. However, they're not the most budget-friendly, and issues with sizing and overheating might make you want to look elsewhere, especially for sensitive devices like smoke detectors.
