Thanks for the guide! Just replaced the batteries in mine - oddly, the original batteries were “Zenipower Z55”.

Glad I didn't have to throw them out and buy another set (lookin’ at you, Apple and Samsung!)

No idea how you were so smooth with opening the case, took me ten minutes going around in circles for each bud lol

This worked like a charm ? One thing I noticed however: I don’t know if it’s a design chance with later revisions, but when I popped my cover open, the touchscreen and microphone assembly were firmly attached to the cover. Thus, the cover did not separate from the board, like shown in the video. Meaning that if I hadn’t been careful with the plastic picks, I could have accidentally sliced the ribbon cable connecting the touchscreen/mic assembly to the board! Keep that in mind and be careful! Even though these have a difficulty level of “easy”, they are DEFINITELY not meant to be opened and/or repaired!

Thanks reallyhelpful video

but Just becarful when putting the metal thing on the battery because you can short circuit the battery (produce heat and may explode), I think it is safer to first put back the metal thing back in the case then put back the battery (cannot short circuit that way)

It looks like the original battery was the A2 and Varta is now providing the A3 and A4 references:

I am thinking to look for the A4 since it may provide additional capacity

CP1254 A3 : 66 mAh

CP1254 A4 : 77 mAh

Very good tutorial!

But I couldn't find any A3, I think they are not sold anymore (at least in France), I managed to find some A4 with a bigger capacity on (ref. CP1254 A4) for 18euro each and it works perfectly well :D

I replaced the existing cells which were a Varta CP1254 A3 & ZeniPower. Im guessing this is because early on in my ownership I had to send them to Sony as one bud decided to just... Not turn on anymore. I can't remember which one was being problematic but these seem to be the two brands that Sony uses.

Like others, I used Varta CP1254 A4 cells in the hopes of longer battery life, I'm about a week into using them and can report that they are indeed feeling like new again, and I'm also having much much fewer random disconnects or power cycling.

Cells were sourced from

Worked great for me too, however as Maximilian S. says, the mic and touchpad were firmly atteched to the cover with a ribbon connecting them to the rest of the unit. This model in the video doesn't have this, as it's a slightly different version. Be careful and you'll be fine.

I broke the glue trying to remove it. Any idea what glue I could use instead?

(I tried without, but it's not working)
