Hi all! In the article I will tell and show these batteries, the use of which is very wide. How to determine which one you need for your device.

This category of batteries differs in size (diameter and height) and manufacturing contents. If we see the inscriptions SG or SR, then these “tablets” are made on the basis of silver oxide. This price category will be higher, since they have a larger capacity and, accordingly, take longer to discharge. At retail prices in stores they will be 50-100 rubles apiece.

More budget options with the designations AG or LR are alkaline (alkaline) batteries. They cost several times less, but their service life will be shorter. You can find them in stores at retail prices of 10-20 rubles per piece.

I counted 14 types of these batteries, I didn’t count batteries for hearing aids, they are similar and in some cases even interchangeable, but the design is slightly different. On the back of the batteries there are codes that interest us with designations that can be used to calculate the one we need.

It is better to put more expensive “tablets” based on silver oxide into expensive and high-quality watches or devices. Since each replacement can be technically complex, it is better to keep the number of assemblies/disassemblies as much as possible. For example, a waterproof watch is very difficult to maintain this moisture resistance after replacing the battery.

In the video I show what all these batteries look like and what they are like, using alkaline ones as an example. How to determine which one you need.
