Battery Types

The primary choices are silver oxide battery and alkaline watch batteries.

Silver Oxide batteries are known for having a higher energy density and thus have the ability to generate more power for their size. These batteries typically last longer than their alkaline alternative.

Warning: These should never be used on a battery charger, ever.

Alkaline batteries are the most frequently used option, and watch batteries are no exception. They have a shorter shelf life compared to silver oxide batteries. They are cheaper to make but the downside with alkaline watch batteries is that they have the potential to leak and could cause corrosion and damage your watch (or other devices that use these batteries).
