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.
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.
