So I just got my new laser from Ledshoppe, 50 mw green and Instead of using a 18650 battery that I was supposed to use, I used 2 16340 batteries like an idiot. So the laser worked for about 3 min, then died unexpectedly. I thought it was just the batteries so I charged them for like 30 min and tried again, and still no luck. What I'm trying to figure out is, did I fry/break my laser already by using the wrong batteries? Or is the laser just defective? Thanks.
