I repair macs and just hate the battery job on your model. It would be reasonable to have Apple do it. It’s expensive, but it’s a better quality battery than the third party stuff you get by DiY or going to an independent shop.

That said, it may be messy and time consuming, but you can buy the battery off of amazon and use iFixit to guide you, and save $150.

I’ve done a few of these and it’s possible to do it much faster without pulling the board

That said I would not recommend doing this if you’re not really comfortable doing this kind of work. It’s not a terrrrribly difficult repair if you’re good with working on repair unfriendly modern laptops but if you’re not good with that it can be quite challenging. It’s not as hard as it looks though, the main pain in the ass is the goddamn battery adhesive

Keep in mind that a slipped tool can be devastating (torn ribbon cables can be a nightmare and costly scenario, scratches on the logic board even more so), if you’re impatient while prying the battery and haven’t used enough solvent it can actually be quite dangerous, even stupid shit like if you push down too hard on a stubborn screw to gain torque you can break the lcd (which is easily like $300+ and a much more involved repair)

It’s also verrrry difficult for anyone but Apple to source a legit Apple battery (and people will shit on apple for this but literally every company does it; try to buy an oem battery for any laptop or phone. It’s not that Apple is good, it’s that they all deserved to get shit for it). Keep that in mind. A lot of third party shops will use whatever they can find and those batteries from aliexpress/ebay often have significantly inferior management controller boards and spot welds. You’ll never know but they’ll fail faster (and sometimes spectacularly). This is a fucked up situation and I don’t know what to tell you; you can try and find someone selling oem batteries pulled from units broken for other reasons but these generally are $$$ for batteries with questionable life. Plus there are a ton of sellers that are happy to say they are selling oem batteries with counterfeit labeling (and will often have “warranties” that say if you remove their counterfeit labeling to prove it’s fake you can no longer return it)

The big things are to somehow indicate to manufacturers that it’s not absolutely critical that a device has to be the absolute thinnest thing in the world. More importantly by far parts need to be available, especially things that absolutely will wear like batteries. This needs to happen via political pressure and regulation because Apple, hp, acer, dell, etc have shown consistently that they will not do this. They will produce those parts for a limited period of time internally and they will almost never make them available to external suppliers (exceptions of half hearted efforts like apples self service program, which has parts purposely priced just high enough to make it so it’s about the same as just getting the service from them).

This won’t happen. It’s consistently failed. Political machinations in the USA (where many of these companies are based out of) consistently favor corporate interests and lobbying

Hope you learned you lesson and will never make this mistake again.
