![]() ![]() ![]() ![]() They give a voltage of 1.5 volts and have a capacity ranging between 15 to 17 milliamp hours or mAh. Now that we know how to identify battery types by their prefixes, what exactly is the difference between these 3 types and should you be worried about what battery is in your watch before buying it? Let’s take a look:Īlkaline batteries are the least expensive of the group and, as such, are seen the most in cheaper watch models. So, in the image above, you know that that is an alkaline battery by the AG shown on the metal. Lithium batteries will be represented by BR or CR, alkaline batteries are represented by LR, L, or AG, and engravings showing SR or SG denote silver oxide batteries. An easy way to do this is by looking at the prefixes or the letters at the beginning of the writing on the battery. The main difference in the types of watch batteries is their chemistry and typically your watch will have one of 3 main types of chemistry:īefore we go into the internal differences of each type of battery, it’s important when taking the battery out of a watch or when shopping for and new one to know which type you’re looking at. To the average person, a watch is just a watch – you know that they’re used to tell time and they’re stylish, but have you ever wondered what’s underneath the hood of that timepiece on your wrist?Īnd more specifically have you ever wondered how watches work, what’s powering your watch, and whether the same type of battery is powering all the watches around the world? In this article, I’ll take a dive into the question “Are all watch batteries the same?”Īll watch batteries do not use the same type of battery and, in fact, there are some very distinct differences in the size, width, and thickness of the different watch batteries.

If you are unsure that you need a 391 and/or 381 battery and need to find the equivalent of that size, simply check out our Watch Size Battery Guide. If you have a question about the best fit for your battery needs make sure to give us a call at (800) 515-BIAF. 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. We carry top quality cells from Vinnic, Maxell and Energizer with quantity pricing 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 381 battery is the equivalent of a SR1120SW battery, which is also the same is a AG8 / SG8 battery. These watch button cells (also are known as coin cells) fit many sizes. ![]() has an abundant amount of size 391/381 watch batteries available. ![]()
