Do u know which style of battery it use?

[Evans]

It's the real 650nm Red Laser Pointer which I buy a month ago.
According to this picture , who can pick out the style of the battery?
Great appreciate.
It's said that the laser pointer can not be continuously used more than 2 mins?
Is that right?

Hi,
E,
That looks like a cree C8 if to is it will take 1-18650 or it can take 2-18350 cells. Don's buy cheap cells AW, Panasonic,LG,Sanyo are the better batteries.As for the 650nm diode read the data sheet for it ,it will tell you the maximum amp's to run the diode on.

The photo isn't clear enough but yes it looks like something that would take one 18650 or two 16340, not every host that takes one 18650 can fit two 18350 or at least not just any 18350's. Anyway you can't use two batteries if the laser is supposed to use only one or it will kill your laser, so be sure you know if it's supposed to use 1 or 2 batteries.

About the 2 minutes duty cycle, yes that's right, be careful not to run it too long at a time or it won't last long. This is true of most all battery powered hand held lasers but the length of the duty cycle will vary a lot depending on the laser, many can't run as long as 2 minutes.

Ok, thanks for your kind reply. I'll try it .

Pretty thanks for your suggestion about not long time use. I think the 2 pcs 16340 Battery will function well.
Appreciate your suggestion,
Thanks

It looks like 18mm wide batteries would fit, however if only meant for one 18650 and you install two 18350's you could damage your driver/diode.

It won't hurt to try one 18650 first.

Ok, I'll try, thanks
