I've clean it and try doing the circuit outside the pen's body, doesn't help :undecided: Actually Akaline is the first battery I tried. The laser started to dim when its voltage is 1.52 - about a minute or so after constant emission Here's the picture. Note that the laser dims instantly...

I've a problem with my green laser pen - the laser dims rapidly after I turned it on. Here's some info: -The laser works perfectly for only few minutes before the symptom occur -I've tried new and high quality NiMH but it dosn't help - the life is still short -There's no sign of dim red light or...

Will those NiMH batteries works? For the laser, 2.8V is the trigger voltage and 3.2V is the working voltage. 2 NiMH batteries provide only 2.4V, making me uncertain.

I recently brought a 200mW green laser and it require two AAA alkaline batteries. My problem is the laser drains the batteries WAY TOO FAST! After about a minute of constant emission, the voltage deceased from 1.58 to about 1.51. After about two minute, my laser starts to lose its output power...
