What's the difference between a silver oxide battery vs an alkaline watch battery?

For several of our battery sizes, we carry both Silver Oxide and Alkaline chemistry batteries. So what's the difference between the two (outside of price)? Well, Silver Oxide batteries often have a higher energy density and have the ability to put out a high current for their size. These batteries typically last longer than their alkaline counterparts. These should never be used on a battery charger, ever

As for alkaline batteries, they are often used for most kinds of batteries, and watch batteries are no exception. They have a shorter shelf life compared to silver oxide batteries, but they still last pretty long regardless. They are cheaper to make (hence the smaller cost), the only problem with alkaline watch cells would be that they could potentially leak and could cause corrosion and damage your watch (or other devices that use these batteries.
