Rechargeable AA batteries are a thing. I use them in everything: mouse, toothbrush, clock, controller, torch, electronic scale, milk froth wand etc.
Whenever a device runs out of juice I pop fresh batteries in the device and pop the depleted batteries in the charger.
It’s great. Charge lasts much longer than chemical batteries and they work for many years. I wish everything used rechargeables.
I grew up with rechargable AA and AAA batteries. They were great at the the time. But I only have one device left that uses them, some at least 12 year old logitech keyboard.
Just recently bought a fan with a remote control (Don’t have an AC, so you really need at least that). I had to buy some AAA batteries for the remote. Haven’t used those in close to a decade.
