Devices with internal batteries basically have embedded expiration dates.

Standard AAA or AA can be rechargeable so you don’t need to keep buying more. I’d suggest buying like a 100 pack or something, they’re not expensive.



The ideal would be rechargeable AA battery support with a built-in USB-C that would natively support charging said AA battery.


AA batteries have lots of different chemistries and they require different chargers or can't be charged at all.


At this point so many battery packs use the 2 double-a batteries side-by-side, I wish they just sold those as a usb-c rechargeable cartridge, that would make a lot of sense


You can also get a USB charger for them which is very convenient.
