I’ll take your word for it. When I need new ones, I grab a couple at the gun shop when we’re there. I just know they’re not vaping batteriesIt's not that they're flashlight batteries, it's that most are protected and batteries that work well for flashlights are high mAh low CDR. The high CDR simply isn't needed for modern LED lights.
I switched to 18650 lights because CR123a batteries aren't cheap and I can vharge e cig batteries and flashlight batteries in same charger.
