Yes and those batteries go in the back of our refrigerator. For many types of devices, a clever person can either find compatible alternatives or hack a rewired connection to a newer battery.
The larger issue is the growing dependence of devices on networks. I've got an old Nokia phone that even if the battery were fine, the phone can do nothing because AT&T turned off the D-AMPS network about 10 years ago. Unless I find a D-AMPS celltower on eBay (and operate a pirate cell service that interferes with new phones using the same frequencies) that phone is now a paperweight.
It's going to get worse because so many devices depend on the cloud for basic functionality. Microsoft just announced the end of some services on Windows Phones ( https://www.engadget.com/2018/02/19/mic ... -8-phones/
). Keeping those kinds of devices running requires replicating the company's back-end servers (and having the company's security codes).
