I know these are currently out of fashion but I’m still thankful they exist.
Let’s remind ourselves of devices that use(d) these standardized batteries:
Toys
Digital cameras
Torches
Gadgets like fans
Wireless keyboards
TV remotes
Thanks to having a standardized system of batteries,
You can use the same battery across several devices. This is a no brainer but it’s very practical.
Batteries can charge quicker thanks to being put in a dedicated charger and not being limited by USB cables. (But yes I concede that USB has been updated for faster charging over the years)
Devices don’t have down time when their battery is charging. To charge, the battery is removed from the device and can immediately be replaced with a fresh one.
You’ll never have to trash a device due to an expired battery. Just buy a replacement. And building on this…
Any improvements in future battery technology can be retro-fitted into your existing devices. And there is a high incentive for future improvement, because…
An accessible (due to easy replacement) and large (due to many devices) battery market is very attractive to competition.
If you look at the pros I listed, they all happen to be things that would be very useful for electric cars. So I think it would aid the adoption of electric cars if their batteries were standardized too.
Do you mean built-in rechargeable batteries? Because that’s way worse than removable batteries.
Zigbee smart home devices last a very long time on cell batteries (CR2050 or something similar) that I’m not really worried about those. I’ve got door sensors that have been going for over 2 years on the same batteries.
No - look at the IKEA smartphone line (TRÅDFRI and the like). They have stopped producing Zigbee devices that require CR2032 batteries and have released larger units that take AAA/AA rechargeable batteries.

I wouldn’t say they’re out of fashion - a lot of smart home devices are moving away from disposable cell batteries and over to rechargeable batteries.
To built-in lipo batteries that go bad after a few years and you have to trash your device or tinker?
No - rechargeable AA/AAA batteries.

That’s good to hear, I had a feeling it was all moving in the direction of glued in battery + usb
