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

Jason - Antwoord

could you provide the link to buy those batteries and also what is the battery life now after replacing?

Shivam Patel -

I had the Zenipower batteries as well, but could replace them with the Varta without any problems. Ordered them on Amazon. The guide was superb!

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!

Happened to me on one of the earbuds! I do believe that it came from wear and spread of the adhesive that usually attaches the touchscreen/mic-assembly to the inside of the bud instead of the top cover.

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)

Thanks for that. I put mine in and went back in to find a very hot battery the first time. Hopefully it's better the 2nd time.

It looks like the original battery was the A2 and Varta is now providing the A3 and A4 references: https://www.varta-ag.com/en/industry/pro...

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

CP1254 A3 : 66 mAh

CP1254 A4 : 77 mAh

Julien Bataille - Antwoord

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 conrad.fr (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 Conrad.com

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)

Maxime - Antwoord

Great guide! Although I would recommend to not go too deep with the opening tool. I broke a plastic part. No big deal, there are still other plastic hooks on the case and there is glue below. But still.

Question: my brand new Varta battery was hot when I took it out of it's anti-static bag and removed the plastic sheets around it. Is that normal?

Alex - Antwoord

I purchased the new batteries and swapped them in. Now the Bluetooth doesn't work on the left ear bud. Its super strange because the charging case lets me do a hard reset and soft reset on them and they're fully charged but when i go to pull the pair out of the case only the right one flashes blue like its ready to pair for Bluetooth.

super easy to do but i think i bricked them or something.

Thanks for this repair guide, it was super easy to replace the battery and keep using the earbuds!

Davy Appelo - Antwoord

Easy - T*H*A*N*K**Y*O*U*!!!
Saved my earbuds after they fell into a bathtub, fully submerged. Immediate disassembly, part separation and drying recovered both the battery and the electronics.

FREDRIK PRINCE - Antwoord

Need to be careful when putting the metal contact on the new battery because if the metal contact also touches the side it will short the battery. I accidently did this and luckily noticed that the battery was getting hot.

Atticus - Antwoord

Simply amazing. Flawless tutorial, simple, straightforward procedure! My left bud's charge kept dropping to 10% within an hour and I was prepared to be forced to replace the entire set when I stumbled across this tutorial. Great job. I put in the A4 aswell and it seems to work just fine. I am really pleased that it is at all possible to replace those batteries. Thanks a lot!

Sabine Funk - Antwoord

The right one isn't playing anymore, though it charges, connects, blinks blue and responds to touch input! Can't tell what I've done wrong but a slight scratch(oh, barely) on the large ribbon cable at the top(inside part).

So sad :(

Smeargle - Antwoord

Installed the A4 batteries. The flatflex cable was attached to shell not the battery holder.

Thanks Ludovic!

Without your video I wouldn't have dared to open my Sony WF-1000XM3. My issue was not the battery but the right pod did't sound right any more. It was extremely quiet and when turning the volume up it started cracking and clipping. I first tried resetting and re-initializing and pairing with different devices but nothing would help. Then I noticed that I could get a slightly louder sound after shaking the pod a bit. I suspected that it was a an issue with the speaker. With your guide I was able to disassemble the pod - only to discover that I was not able to reach the actual loudspeaker because the last circuit board is glued to the case, effectively locking the speaker in.

However, after I had carefully reassembled the pod, I was delightfully surprised to discover that the pod was working perfectly fine again :-). Even if I found no smoking gun, it most likely wasn't the speaker. And in case the problem reappears, I will first investigate the contacts that are accessible.

Tried this and unfortunately one of the small screws was stripped and I'm unable to get it out - tried rubber band (not sure given it's recessed location if glue would work). Any recommendations?

Hello,

after doing the battery replacement on my right ear bud i cant turn it on.
it charges while in the case (red light on) but if i take it out it just goes off and nothing else happens.
I tried doing the reset (holding for 20-30sec on one side) and also the initiation process (holding both for 7 sec.) but nothing happens.
everything is fine with the left side.
i dont think i damaged anything while opening it, although it seems like the touchpad isn't working anymore.
i also changed to the old battery again but its the same problem.

any help or ideas would be much appreciated :)
