You can replace the batteries in your earbuds if you have the right soldering skills, just be careful not to damage the plastic. The batteries have model number 541112, you can order them from sites like AliExpress.

-
These earbuds are held together with plastic clips, rather than the glue seen in more expensive models.
-
Insert a sharp knife into the the seam, and carefully work it around the earbud to create a gap.
-
Carefully separate the two halves, but remember they are still held together by wires.
-

-
-
Pry out the battery and rotate it so that the back faces towards you
-
Remove the yellow Kapton tape and black foam pad from the old battery
-
The two solder pads on the battery should now be exposed. I don't recommend touching the solder pads on the earbud's circuit board as there is much less space to work with, making it easy to damage.
-
Carefully heat up each solder pad and pull away the wire from each one.
-
-
-
If your new battery comes with wires, like in the photo, you should remove them like in the previous step.
-
Line up the red and black wires with the corresponding + and - terminals on your new battery. There should be marking to indicate which is which.
-
Solder the connections. Now try testing the earbud - if it turns on, congratulations! Replace the foam pad and add new Kapton tape if needed.
-
You can apply a bit of glue to keep the battery stable. Now simply push it into place, and pop together the plastic parts.
Don't forget to recycle your old battery!
