> 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. 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.

I didn't say "unpackaged" or "unprotected". But I've seen the internals of multiple devices that have simple plastic wrappers (not hard shells) around the various battery cells, with wires connecting those plastic wrappers, and they don't have duplicated battery electronics, just one set.

  I'm not sure how that is relevant to the right of being allowed to swap parts. If you can't make parts yourself but you can take salvageable parts from a broken device. Why should you be prevented from doing this repair? Also, why should third party manufacturers be prevented from making compatible parts?

Why should you be prevented from doing this repair? 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.

  You mean pouch batteries? Those things are pretty durable.

  Those are pouch batteries, they never need a hard shell. 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.
