Do all flashlights slowly discharge when not in use? (kbin.social)

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.

To add to this, if you are going to store your Li-ion batteries for any period of time then you should charge them to 3.7v instead of a full charge. This will extend the life of the battery

Good tip, but the OP should be aware that when at 3.7V they have only ~50% charge in them, so remember to also pack a spare or two (at the same voltage) to have the same total runtime.

Should be closer to 60% but still, it's not in a long term ready state. Long stored batteries should be recharged before use.
