Most devices & gadgets are rechargeable nowadays. The only thing I have that still requires batteries is a headlamp but even those are available in rechargeable varieties. House smoke detectors need a battery too.

A already is and D and C seem on their way out. AA and AAA will likely need an equivalent that’s worth it to change over. 9v for smoke detectors is unlikely to be replaced by a battery, but I swear by mains connected smoke detectors.
Ultimately I wish these were being replaced by standardized rechargeable. Take common voltages/amperages and sizes and just make RA,RAA,RB… for simplicity. I love my rechargeable AA and AAA cells until then
Smoke detectors that use replaceable batteries are illegal in some places already.
Basically a modern smoke detector should have a non-replacable, 10 year sealed battery, and be discarded when it’s dead. The rest of the detector goes bad after that so it’s better to just have it all die at the same time.
18650 would be nice
