Use this guide to replace the battery in your MacBook Pro 16" 2021.
The MacBook Pro uses stretch-release adhesives to secure the battery. Some of the strips are hidden underneath the trackpad, so you’ll need to remove it first to access the strips.
For your safety, discharge the battery below 25% before disassembling your MacBook. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.
You'll need replacement adhesive in order to complete this repair.

Where can I purchase a new battery for my MacBook Pro 16" 2021 laptop?
Hi there!
Unfortunately, we are not currently selling MacBook Pro 16" 2021 batteries. We are hoping to sell them sometime soon. You may want to consider checking with other retailers or online sources for the specific battery you need.
Has anyone figured out where we can purchase new replacement batteries for this computer (MacBook Pro 16" 2021 Model # MK193LL/A)?
Why does step 22 talk about installing a new trackpad? That part left me confused.
Hi Ted!
Great question...and I don't have a great answer in return. So, I have changed the step accordingly!
Where can I buy a new battery for my MacBook Pro m1 16 2021?

Hello, I have received shaking after completing all the steps. Is there an adhesive applyer?
Where are the replacement adhesive pull strips? It's odd they are not part of the iFixit kit.
The kit I received had adhesive already on the back of the battery. It made it easy to place battery in laptop and press down to secure it.
Der Austausch der Battery brachte mir überraschend nichts, bei eingeschaltetem Bildschirm (ohne Tätigkeit) entladete sich die Batterie in kürzester Zeit. Zufällig sah ich aber beim Verkäufer, dass die meisten Käufer auch ein neues Ladegerät mitbestellten: nun habe ich ein Zweifel, ob man nicht etwa genauso ein neues Ladegerät braucht, um die Batterie "richtig" aufzuladen? Finde ich auch seltsam, dass hier im iFixit darüber nichts gesagt wird.........2)meine Frage ist auch, ob man eine Neu- "Kalibrierung" nach der Installation machen muss?
3.) bei der Neuinstallation der SSD NVMe Speicher wird das Volumen erst gar nicht erkannt, "Time Machine" mit Backup ist leer......wo könnte ich eine Anleitung für die Installation bekommen? MacBook Air (13-inch, Early 2015)
Prozessor 1,6 GHz Dual-Core Intel Core i5
Speicher 8 GB 1600 MHz DDR3
I completed this replacement using the battery and tools from iFixit for $150. The replacement process worked well, and my comments for others is to be careful when taking old battery out not to damage the screen. I had to pry the battery out of the case and noticed that I was lucky I didn’t damage the screen when doing this. You can’t see under the battery when you’re prying it, and there are places you could damage screen if you pried in the wrong spot.
The other comment is that my laptop wouldn’t recognize the new battery once I installed it. Perhaps there was something else wrong with my laptop. I paid $850 for Apple do the replacement. The Apple repair site has instructions https://support.apple.com/en-us/100585 Apple sells only the battery, keyboard and top case as one unit for $615 plus $88 credit if you return your parts so about $530.
This looks like one of the most unpleasant mac repairs since I cracked open a PowerMac 6500. How difficult/frustrating is the stretch adhesive?
It'd be frustrating if I'd cracked my screen so be careful of that. The adhesive didn't release with the rubbing alcohol so I just had to pry and pull hard on the battery to get it out. It wasn't pretty, but I didn't care that I was wrecking the battery I was removing. The new battery had the adhesive already applied to it, so it was easy to install.
