5mw green laser pointer with 18650 battery?

[guile_mrd]

I have a 5mw green laser pointer that's powered by 2XAAA batteries, is it possible to use a 18650 battery instead of the 2XAAA batteries? will this make its output stronger or will it burn it ?

Thanks for your help.

Probably not. 3.7V is a lot more than 2x 1.5V. It could fry the driver of the laser.

did anyone try it? is 3.7v too much for the 5mw laser pointer?

You're making the mistake of assuming all 5mW pointers are identical. You might as well ask:

"How fast can a car go?"
"How bright is a light bulb?"
"What color is vomit?"

It depends how the driver was designed.

the one that I'm asking about is the silver 5mw pen pointer that they sell on eBay.

Probably not. 3.7V is a lot more than 2x 1.5V. It could fry the driver of the laser.

the difference between the 2XAAA 3V and the 18650 3.7V is only .7V will that fry the driver of the laser? how can i test the max voltage that the driver of the 5mw silver green laser pen pointer can take?
