- •Works great in specialized applications like Citizen diver watches when installed correctly.
- •Comes with a 3-in-1 child shield coating, enhancing safety during handling and storage.

- •Affordable compared to many competitors, saving time and money by avoiding frequent store visits.
- •Effective as a light source in dog collars, providing a bright, easily visible glow for safety.
Cons
- •The child shield coating must be removed before use in delicate electronics, which adds extra steps.
- •Requires cleaning (e.g., with isopropyl alcohol) after removing the coating to ensure proper function, particularly in watches.
- •Not recommended for direct use in watches without preparation due to the coating interfering with performance.

Bottom Line
The Energizer 2016 3V lithium coin batteries stand out for their long-lasting power, safety-oriented child shield, and compatibility with car keys and specialized devices like Citizen diver watches. However, plan for a bit of prep work when using them in sensitive electronics like watches, where coating removal and cleaning are necessary. If you want straightforward, reliable power with added safety features and good value, these batteries are a solid choice for both automotive and electronic uses. For users focused mostly on watch replacements without the need to handle the coating removal steps, exploring dedicated watch batteries with no child shield might be worth considering, but for most other uses, this 2-pack combines safety, longevity, and performance well.
