Silver Oxide vs Alkaline Watch BatteriesAlkaline batteries are defined by the letters AG in front of them, IEAG1 AG2 AG3 etcYou should NEVER use Alkaline cells in watches for 3 very good reasons1: Alkaline batteries are 1.5 Volts, NOT 1.55 Volts, your watch was designed to run on this very specific voltage, underpowering it can cause it to keep incorrect time.2: The major component of an Alkaline battery is sodium hydroxide or potassium hydroxide, if the battery should leak inside your watch, it could completely damage your watch beyond repair.3: Silver Oxide batteries have a very "flat" voltage profile, this means they keep producing 1.55v until they are exhausted, alkaline batteries have a "curved" voltage profile which means as they discharge the voltage becomes lower, sometimes as little as 0.5 volts, most watches will stop working at 1.3Volts or less.
