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. They have a shorter shelf life compared to silver oxide batteries, but they still last pretty long regardless.
These should never be used on a battery charger, everĪs for alkaline batteries, they are often used for most kinds of batteries, and watch batteries are no exception. These batteries typically last longer than their alkaline counterparts. 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. What's the difference between a silver oxide battery vs an alkaline watch battery?įor several of our battery sizes, we carry both Silver Oxide and Alkaline chemistry batteries. If you happen to run into two batteries that are in the came category but have 2 difference sizes, it simply means that one battery is often a high drain battery while the other is a low drain battery. For example, a size 399 battery is the equivalent of a SR927SW battery, which is also the same is a SG7 Battery. These watch button cells (also are known as coin cells) fit many sizes. has an abundant amount of size 399/395 watch batteries available.
