I was on ifixit wait list for like 5 months … but they did notify me. When I got mine there was only 2 left. Have to jump online as soon as they notify u. Good luck
Also batteries can not be shipped by air. Thats why they won’t ship to you here in the good ol’ USA. I feel your frustration went thru it with mine…but new battery and ran great. Now flow to fix it from looking like a banana
This is not good. My battery is dead as well. No response from Teenage Engineering (no email reply after several days of waiting) and batteries are all out of stock at iFixit.
Is this really how this story ends? I can’t use my $600 synth because the battery died and I can’t buy another one.

mad, and maddening. You can buy posters, key fobs, t-shirt, and all other sorts of non-essential tat…but not a replacement battery.

Check this post, FIXED battery not charging/100% in app/solid charge light/dead when disconnected/parallel charging
Didn’t apply to my situation but worth a shot.
I adore TE design and the OP-Z and OP-1 are brilliant and unique instruments so I can’t say I wouldn’t get excited for an OP-2 or something but man…the hardware issues and lack of support in general combined with premium prices has been such a disappointment. Crazy to spend $600 on a portable synth that I can’t get error code explanations, public communication/problem acknowledgement, or even a simple new battery for.

Teenage Engineering replied to my support message.
tldr; I can pay at least $50 to send my device to Triple S Electronic & Repair. They will then send me an invoice for the repair price and credit my deposit to that. Obviously my warranty does not apply since I purchased my OP-Z in late 2018.
Unfortunately I don’t even have the opportunity to buy a new battery so now my options are to wait until new batteries come into stock at iFixit or spend however many $100s of dollars to send off to a repair shop for them to replace a battery for me.

Going to give this a shot, thank you!
Posting some links for speciality retailers which carry similar batteries. Just want to share in case anyone wants to further investigate. Not sure yet what I’m going to do. First off, going to reply to TE and see if they can provide a battery to me directly.
I have another follow-up.
After requesting a battery and not a repair from Teenage Engineering support, they sent me a pregenerated link that allowed me to purchase a replacement from them directly for $50, plus $14 shipping & handling.
So, it can be done.

So iFixit, when they have them, sells official batteries from TE (logo and all) for $30, but TE needs to sell them for $64?..for a $600 device that has known battery issues (among other quality control problems) that should be replaced/recalled when those problems are known and apparent? Hmm.
Thanks for doing the legwork either way.

Remember when they were taking op-z pre-orders they said about how long the battery would last (flying over the Atlantic and back or something like that), and then the battery shipped was a big downgrade, which they then boosted up a little with the 1st firmware update? I wonder if there is something a bit more to this than at first glance. My indicators now never hit full, even after a long charge, when in the beginning they would hit max within 20minutes tops.

So much for that. Didn’t work.
Furthermore, when I keep the unit plugged in, it makes what can only be described as a “squeezing” sound. The attached file is really a zip file containing the two audio clips.
Remove the “.zop” extension and extract as a zip to listen.

I replaced the inner pouch cell with the one ordered below from Amazon:
Less capacity, but better that nothing.
You’ll need to keep the plastic frame from the original battery to get everything to align to the charging pins.

Now THIS is what I was looking to see could be done. I don’t have battery issues right now but when the day comes, good to know the cell itself can be swapped

Wouldn’t a 503048 fit? It is 30mm wide instead of 22mm and 700mA.

I feel this should go without saying, but to anyone attempting this, be very careful how you disassemble batteries.

Possibly. I just went with what was readily available from Amazon.
