On many modern devices, you don't have "a battery", you have battery cells fit into every available space and wired together. You're certainly welcome to try replacing those. I just don't want to see that reverted to a discrete battery design.

By all means! And "components" here may well mean "single integrated board", as it does on many laptops and phones.
Source for this. No device has unpackaged unprotected battery cells just floating around.
They may have many discrete batteries to use up all of the available space, but each unit is self contained with protection electronics and can be swapped independently of the others.
As I stated earlier in this thread, you should absolutely have the right to attempt such repairs. I just don't believe that there should be requirements to make devices use more modular components, at the potential expense of other desirable properties.
Each one will have a tiny PCB with protection circuitry on it. It’s the only way to prevent them from accidentally catching fire or exploding.
Batteries are far more complex than most people expect. Especially lithium batteries found in phones. The chemistry is super sensitive, and anything except careful monitoring of each battery pack risks catastrophic failure. Hence the tiny PCB on each battery pack.
WHY?! You'd end up with stuff 3-5mm thicker, but basically the same weight. Let's drop the "thinner" fetish once and for all, nobody cares about some mm of "wasted" space (that usually improves cooling anyway) inside a devices case and it being a bit chunkier, as long as it's almost just as lightwieght!
Fffs, let's go back to getting gold plated or diamond encrusted laptops and watches for showing off status! That's way better than the thinner/lighter nonsense...
Sure, getting smth. thinner bc technology actually improves (eg. displays) is cool, but shaving micrometers by packing everything close together is stupid.
(Oh, and we could start fixing our brains to think the same about cases for... people! Eg. housing. Like in kill the micro-apparments disease, there's enough room on the planet for all to leave confortable... in bigger rooms, and with chunkier laptops if that makes them more recyclable. "Space" IS mostly "free" ya know - very little of Earth's surface is actually usable for stuff like agriculture, energy production, mining etc.)
Then there is no phone that literally has a single board, there are other components such as the camera, earpiece, screen, etc. that are still replaceable.
