I try to carry about a five day supply of rechargeable AA and AAA batteries. Use them in:
- headlamp (to wear on head, not a bike headlight)
- headlight (for bike)
- taillights (I use two)
- GPS
Some trips also carried a weather band radio and/or a small portable AM/FM/Shortwave radio, both of which take AA.
I carry one charger that will charge both AA and AAA batteries. I generally have stayed indoors or at a campground with a power outlet often enough that a five day supply of batteries sufficed.
My camera and computer and phone will not use AA or AAA. My tablet computer can be charged with a USB charger and I have a camera batter charger (Li Ion) that also has a USB output. My phone is usually off, I do not carry a charger for it. I carry three camera batteries.
I also have some stuff like heart rate monitor and bike computer that take CR2032 batteries, I carry a couple of those but only once have needed to change one of those during a bike tour.
If you are considering a high power headlight and AA rechargeables, you might find that you need two or more AA chargers. I can get by with one that takes four batteries, but after several days I have to swap batteries in the charger a few times per night to get fully charged up.
