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.

Fun fact: amp hours are a measurement of discharge over time… I can probably explain this better with an example actually. 48v100ah is four times the capacity of 12v100ah, they can both put 1 amp for 100 hours but at different voltages that’s a different amount of… power? Energy? I always get them mixed up. Anyways the AA guys are 1.5v vs the ~3.7v of a phone battery, so the same amp-hour measurement is a little less than half as much juice. Hope that helps, I’m a little stoned tonight lol
