So is it safe to EDC lithium battery flashlight everyday?
Or should I stick with AA format?
How dangerous are flashlights compared to cell phones / laptops?
Your suggestion for best/safest batteries for Zebralight SC62w 18650?
The answer is No! - but only if you think driving a petrol (gasoline) powered car every day is also equally dangerous due to the volatile liquid fuel you carry in it.So is it safe to EDC lithium battery flashlight everyday?

BTW - you may want to check what battery chemistries mobile (cell) phones and laptops use.
A user of these other Li-Ion powered devices still needs to have some basic safety knowledge, for example, don't charge your cell phone under your pillow at night (yes, there are people who do that).
A properly designed device will terminate charging or power-down if thermal constraints are exceeded. They are supposed to be designed so that they can be safely used by a layperson with no special knowledge of Li-ion technology.

Don't be in a hurry, get yourself a nice AA light to start with, maybe the Zebralight SC52. That way you'll have a GREAT pocket light and won't feel the need to jump head first into lithium-ion technology too quickly, and you'll also be better prepared to wisely spend your hard earned money.
The nice thing about the SC52 is that it will take regular common alkaline AA batteries, or for better performance you can use common, and safe, AA rechargeable NiMh batteries, like Eneloops. The kicker is that when you DO finally feel ready to start using lithium-ion cells, the SC52 can use those as well, with the bonus of quite a jump in brightness.

That's comparing apples vs. oranges. The designers of laptops and cell phones have complete control over safety issues since they control the complete system design, using industry-standard safety mechanisms such as Smart Battery specs. But this is not true for (most) flashlights.

Not so sure about this, I believe it is still up to the user to understand enough to make sure they do not attempt to charge a cell that that has been over discharged, or put a 4.2V cell into a 4.35V charger, etc.Gauss163 said:A properly designed device will terminate charging or power-down if thermal constraints are exceeded.
