Hey folks!
Sorry, I *KNOW* this is going to seem noobish of me, but I need a little assistance.
I am in the process of trying to do a review for a laser, and it's not working. I've GOTTEN it working temporairly, but as of right now it's basically dead... My problem is that I'm not familiar with the behavior of these 3.7v batteries. I'm used to older laser pens where you just plug in AAA's and go. This is a slightly newer territory for me.
So here are the symptoms:
When the battery is inserted, the red LED above the switch comes on indicating that I've depressed the button. (So there's power to the driver anyway)
There is IR but only for a very split second. When I use my cellphone camera to watch for IR, what happens is when I press the button on the laser, for a VERY brief flicker there's a flash of bright-purple light and then nothing.
Normally on a burnt-out diode, you'd see a steady stream of IR as you press the button which makes me guess about what's going on here.
It WAS working - when I first got the laser, it didn't work. I tried charging the battery, but the light on the charger was green so I figured it was charged. I put the battery back in, and boom - laser worked.
Then after 3 minutes it stopped again and the symptoms listed above continued.
I suspect that the battery is just low on juice, however I have no way of confirming right now. I'm not even sure if this is a protected battery though I suspect it is (UltraFire LC 18650 2400mAh in blue)
I was really hoping for a general concensus as to what the problem might be. I don't want to over-charge the battery if it's full (When I charge it, the green light comes on the charger, so I figure that means it's full), but I really just hope the laser isn't dead.
I don't have another battery to test with and my multimeter is at home.
So with all of that being said, given the behavior listed above, what do you think might be the problem?
