Unfortunately, with the current trend of cheap electronics switching away from standard batteries and towards custom-sized, permanently soldered-in lithium cells (sometimes without the ability to recharge them - why this is still legal is beyond me [1]), you won't be able to keep doing that for long.

On the flip side, a lithium cell salvaged from such a device is going to be a lot more useful than a single-use coin cell if you can solder. There are readily available modules that will take any of these batteries and provide a charging port and an output with overcurrent and undervoltage protection, ready to be wired into anything capable of running on 3.7V [2].

That dates all the way back to at least the Dreamcast. When I work on them I desolder the old battery and solder in a socket. Makes replacing the battery a lot easier.
