It's a TI BQ40Z50-R3. I would strongly recommend doing a pack replacement rather than cell replacements for a Framework Laptop Battery. We'll be making replacement battery packs readily available at a price point that hopefully makes it the clear choice.

The question is whether it will be possible to get a replacement battery five years from now (at a reasonable price point).

What helps us keep replacement parts available is that we'll be continuing to build new Framework Laptops with form-factor-compatible modules for the foreseeable future. That means we will still be manufacturing new batteries compatible with original Framework Laptops for many years.

Exactly. Apple even have third-party batteries in their supply chain (installed by an AASP), the printing of the warnings on the cells and the PCB date code look very suspiciously shanzhai. Yet Apple Support were able to confirm that the order number is real and the part came from them. They charged me $600 for it too. It'd better be reliable, unlike the $100 third-party one that idles at 12V, and a voltage spike when waking from sleep killed my logic board.

Do you live in a city without an Apple Store? MacBook battery service is $199 USD for their most expensive models: https://support.apple.com/mac/repair/service

I paid exactly $288 SGD to get my battery replaced at the Apple Store here in Singapore.

I'm in Auckland, and there's no Apple Store in New Zealand. The $600 price is in NZD, too, which means $418 USD.

It's not possible to replace only the battery - an AASP will replace the whole top case. I also think it's more expensive for older models, because the parts are not easy to find for a 2014 computer.

Yeah, this is true for Apple's battery service as well. I got a new keyboard and trackpad for the $288 SGD I paid.

This would only make sense if parts weren't ordered from Apple directly. I would imagine that they are able to as an AASP. Apple products only enter their vintage list after 5 years, and their obsolete list after 7 years: https://support.apple.com/en-us/HT201624

In this case, it looks like the AASP would still be able to order parts for your 2014 MacBook without extra cost.

The AASP got the part from Apple, but charged me 600 NZD and the parts look shanzhai (blurry printing on the cells, wrong PCB date code).

Apple Support confirmed the order number is a genuine Apple part. Makes me worry about Apple's own supply chain quality.

The AASP also did a pretty shoddy job at repairing: the case screws were in the wrong positions, and the logic board was seated badly so I couldn't plug in USB. I just spent an hour this morning reseating the logic board myself.
