Default I need help from a pro on handheld green lasers

ok so i just made a 120 mW green laser and it is inside a 2 AAA housing. It requires <600mA and 3-3.6 volts. I plan on using rechargable batteries which are 1.2 volts each... Will it make it more dim? and are there 1.5 volt rechargable batteries?

OK so ... a pair of e2 cells will provide 3.4 volts at full charge. A current draw of under 600 mA isn't a problem. You can also consider a single rechargeable LiIon cell at 3.6 nominal volts but using "dummy" conductive spacer.
How did you make this green module? is it using your driver? Most modules similar to an O-like are rated for 3 volts.

I use digital camera rechargeable AA cells in my pointers without any noticeable difference.

The voltage drop from alkaline batteries will make the performances nearly identical.

Hey Hotshot ---

How did you build that green? What driver are you using? We can't help much until you answer the questions. Your driver may be a buck driver, maybe a boost. What is the driver. What 808 pump are you using in your module? Drawing < 600 mA, I can't figure out your system.
