I was thinking about buying a wurkkos fc11 as my first flashlight but it said they recommend untwisting it in a review to avoid making a connection so it doesn’t discharge while not in use. Do I need to worry about that with all flashlights? I was planning on keeping it in my backpack so I have it whenever.

    Everything but lithium primary or eneloops in a light with a mechanical switch will have battery self-discharge (bonus: neither of these two battery chemistries leak). An e-switch adds a bit more parasitic drain, so the best bet for a light that won’t be used for a long time is CR123A or white eneloops, and if you’re not sure what the switch type is, you can just break the contact of the batteries.
