The analogy I get between 18650s used in lower power devices is like a word processor now requiring a super computer to run
I just use 18650 cells for everything that may require a battery change too often.
18650 cells are plentiful and inexpensive.
Electronic projects, radios, multimeters.
On low power devices I just run them for months , throw them on a charger once in a while (no matter what charge) and swap them with other devices that require more power.
Each cells should see more/less the same wear over time.
Even an analog oscilloscope I can run on 4x18650 + boost converter.
Scope requires around 500mA at 28V.
Comes handy in places where there's no mains available or when measuring mains-referenced voltages of various power converters (welders, VFD).
It also comes with a DMM function.
I'm the kind of person who solders an AA battery socket in the place of a button cell.
No need to keep around few types of batteries, low power device basically runs forever and replacement battery can be purchased anywhere.
