Default Newbie Question

Hi All - I just joined the forum and I have a question... Probably one that has been asked before but I was unable to find anything when I searched.

I have a WL Fusion 125mW that takes 2x AAA batteries. I was curious if it would handle more than 3v. So if I placed a rechargeable Li-ion 3.7v AAA and a dummy would it damage the laser? What about more than 3.7v?

The laser has an issue where the beam splits with anything other than super fresh batteries, and even then it splits after running for 15-20s. I was thinking it might hold better with slightly higher voltage?

Admittedly I know nothing though...

The Fusion is a greenie correct? Going much above 3v can damage some drivers. Sounds like you are have mode shifting, and not really much You can do about that without replacing some components. It could be a driver/IR Diode/Crystal issue.

Yeah it is a greenie, and I have had it for 4 years now and used it quite a bit. It would be an expensive "experiment" to put 3.7v through it I guess.

You could try using Lithium AAA's that should be safe, but they will get expensive if it eats em like candy.

Not knowing the driver specs it would be a gamble. Most quality green drivers can go to ~4.2v MAX...It's not worth it unless you are willing to burn it out if it can't handle it.
