My flashlights use replaceable chargeables. I want to say “16550” but I’m not sure of the numbers. They’re larger than AAs, longer than Cs but not quite as thick.
Close, it’s 18650 cells which are super common. Even stuff like laptop and EV batteries may be composed of them.
Fun fact, the numbers indicate the physical size -18mm diameter 65.0mm length. The same applies to those button cell batteries - CR2032 is 20mm diameter by 3.2mm thickness.
You can almost always replace the battery, even when the manufacturer doesn’t want you to. As for flashlights, they typically come with easily user-replaceable ones, often even sold separately. Worst-case, you can get a AA or AAA flashlight and use rechargeable AA/AAAs.
Do you have to replace things with broken, End of Life or dying cells often?
I notices a lot of things falling into planned obsolesence because “it’s rechargable” and you can’t replace the battery.

Right. 18650! Thanks!
And TIL what the numbers mean. Cool!
