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.

      2400mah? No way they’re that small, that’s basically the size of a phone battery, hell an iPhone 16 has a 3600mah battery.

        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

        These standard AA rechargeables are 2500, from what other users are saying about losing capacity for the charging circuit, seems accurate:

        Yeah that extra circuitry costs 400mAh vs my rechargeables with a base, plus it makes them more stealable.

      Putting the charger circuit inside the battery takes away battery capacity, so I still buy the external chargers
