Today, I will discuss topics that will give you a full understanding of watch battery Sr626sw, its uses, how to buy the right one for you, how to replace it, and more.

This will not be a long guide, but it will definitely answer all your questions throughout the blog.

So, let’s get answers one by one.

What Is an sr626sw Battery?

Sounds like a random string of characters, right? That’s what I thought, too. But after some research, I found it’s actually a compact and reliable silver oxide button cell battery.

It is small and round, but it has a lot of power for its size. This battery has a voltage of 1.55V, which is perfect for providing a steady flow of energy.

The SR626SW usually has a capacity between 28 and 40 mAh. This tells you how much energy the battery can keep and how long it can run your device until it needs to be changed.

Am I being too complex in my description? If so, just understand that it’s only a battery model.

It’s the power source for small devices like wristwatches, medical tools, pocket calculators, and other gadgets. Who knew such a tiny battery could be so important in our everyday lives?

How Do SR626SW Batteries Work?

I am now going to explain one important part here. I could not find many articles that discussed it before. However, I still haven’t discussed how SR626SW batteries work. So, it’s time to talk a bit about the process.

These batteries work by using silver oxide (Ag2O) as the positive part (cathode) and zinc (Zn) as the negative part (anode).

These parts are split by a paste called an alkaline electrolyte. When they work together, they create an electrical current.

During this process, silver oxide changes, and the zinc does too.

In simple terms, electrons move from the zinc anode to the silver oxide cathode through the circuit to give power to your device.

You can think of it as the “pressure” that pushes electrons through a circuit.

Basically, a higher capacity means more energy.

A Comparison of SR626SW with Other Watch Batteries

Some people kept getting confused and asked whether is 377 battery same as sr626sw or not.

The 377 and SR626SW are the same and can be used as replacements. The 377 is also a silver oxide battery. It has the same size and voltage as the SR626SW.

Some manufacturers label the same battery differently. But that’s only for their business profits and nothing else. Just note that, for most cases, you can use a 377 in place of an SR626SW. However, 377 is not the only model that is sr626sw battery equivalent.

Yes, there are more. Let’s see what other batteries are available that are similar to sr626sw or different from this.

Let me tell you, this part really took a lot of time to write. And the behind struggles were too much. However, here’s a table highlighting these differences:

That means 377 is the battery type that is 99% similar to SR626SW. The other two types are different from what our current model uses.

As I said above, you can interchange 377 with SR626SW; now, the next topic that you want to know is how to replace the SR626SW watch battery, right?

Let’s talk about the process right below.

How To Replace SR626SW Watch Battery?

If the question is with what to replace with SR626SW, we know 377 is there. Now, you don’t know how to replace this yet.

The process is simple, but starting it without following a proper guide can really mess it up. And if this is your first time, you’ll start crying in the middle. Because, to be honest, it’s a bit complicated.

Let me show you how to do it below:

1. Take a small screwdriver (usually a flathead), a case opener, and a new SR626SW or compatible battery (like the 377).
2. Place your watch face down on a soft cloth.
3. Work in a clean area with good lighting.
4. Use the case opener or a small screwdriver to pry open the back of the watch gently.
5. Can you see the screws around your watch? These are too tiny.
6. Open them one by one by putting the screwdriver on the screw head.
7. Now, turn the screwdriver counterclockwise.
8. Don’t force it. Some watches may have screws, and others just pop open with a little pressure.
9. Once the back is open, you should see the battery.
10. Use a small tool to lift the old battery out carefully.
11. Place the new SR626SW or 377 battery into the slot with the positive side facing up (it is usually marked with a “+” sign).
12. Press it into place.
13. Again, carefully close the watch case.
14. Position all the screws in the hole.
15. Tighten them with your screwdriver.
16. Now, turn the watch right-side up and check if it’s working.

Your watch should work fine now. That’s how you can successfully replace any battery of a watch.
