Are 364 and 377 watch batteries interchangeable

About butten cells, I may have a few lines to share with folks and hopefully, useful:

Numbering system -
Apart from the IEC numbers, almost each factory has its own numbers, so they are confusing for consumers. But one can easily find the cross-reference chart from the internet. We can see the numbers combine with "S" or "L". They stand for Silver and Alkaline respectively. In one time, there were hybrids, with very little silver content in them but claimed as silvers to meet certain premium watch procurement requirements at lower price. I don't know what's today now, but we can only trust the designations from major brands and not those from China, nor the counterfeits they export. Without saying, the alkalines are cheap, low in quality and capacity.

Sizes -
There are more than one can remember. Unlike lithium coin cells, these button cell numbers do not refer to sizes, that's one thing added to confusion. I cannot understand why watch movement makers need all these sizes in their designing stages. Button cells all have a nominal voltage of 1.5 volts (except hearing aid and mercury cells in the old days). So, as long as they can go into the battery cavity, you can use them. If you don't have the right size off hand, say the cells are thinner, you can still use them without harm if you have a shim to insert or to raise the contact stripe from under. Note: If you do this, it is at your own risk and never do it on your pricely watches.

Battery Current -
High drain cells were designed for LED or LCD watches that were prevalent in the early days. The stepping motors in analogue watches, in general, require very little constant current, so either type will do. Again, for your pricely watches, you better pick the right ones.

Cheers,

The watch battery cross reference chart or also know as the button battery cross reference chart is easy to use. Find the brand of your battery, then follow it down your battery model. The equivalent battery will be at the beginning of that row. Click on the blue link to go to your battery options and purchase your replacement. For example, if you are looking for a watch battery replacement for your watch, and it was a Maxell SR626SW, you would scroll down the Maxell column until you found the part. Then at the beginning of the row you see what your SR626SW battery equivalent was a 377. The rows are highlighted across for easy reading.

PRO TIP: If you are having a hard time determining your battery, measure the width of the battery and then the height. Use the dimensions against the Dimensions column to find the battery that you need. You can also use a micrometer to measure the inside of a battery cavity to find out which battery you need. Check out the video, Determining my watch battery.
