rechargeable 123s and lasers?

[kevcut1]

I have a weaon mounted Led/laser combo that uses 2 cr123 3.0v batteries. Can the laser handle the rechargable batteries, or will they damage it? The laser is a 5mW class 111a

I hope it shouldnt be a problem. When you buy batteries you need. You can check them out on DEALEXTREME or KAIDOMAIN.

It depends on the laser driver.

If it is current regulated or photo diode regulated, it won't mind the extra voltage. If not you can still get 3V rechargables. (Li-Fe-POs, or Li-Pos with two diodes to drop the voltage)


You could measure the current it takes with full half empty and empty batteries. If the current is stable over most of the voltage range and doesn't start dropping unless they're completelly empty, it is regulated.

If the current drops with the voltage it is not. In this case, the extra voltage could kill it or shorten it's life.


What power laser is it, and where did you get it? Cheap chinese lasers often don't use any regulation whatsoever, even tho they have enough components on the "driver" board.
