quick question

[jahad]

hey guys i have a red laser pointer but i have to use cr2 batterys is there any way i can use differnt batterys even 9v with the wire

If you have a laser that operates at 3V, DO NOT put 9.0V into it! I am absolutely certain it will fry. Can you post pictures? If you can get another battery/set of batteries that has the same voltage, it should work. I once used a CR2 and AA battery taped together in place of an 18650, and it worked pretty well.

[TTerbo]

w8 so it takes 6v? then connrcting them in series should make 6v!! why are you doing this anyway?
have a read Serial and parallel battery configurations

 

[jahad]

let me ask u if i do the 9v would it work?

 

[TTerbo]

well if by work you mean kill your laser then yes it will work

Try rechargeable CR2's from DX or ebay. You should be able to get a charger and batteries for less than $20.00. I use rechargeables in my red dilda and they work fine.

;p so any way of doing this and thanks for replying for fast guys

Did you even listen to what I told you? 3 batteries = 9 volts. 9 volts will kill your laser! If you want to increase the power and still have a chance of a working laser, get a 3.6 volt RCR battery. Any more than that is too much.

 

[jahad]

wtf are u talking about man the batterys im trying to use are 1.5 each

 

[randomlugia]

Sorry, but where did you get those batteries, and why are you using them? The standard CR2 voltage is 3.0 volts, as are the ones that come with the laser:

i have those too but i need to order a charger so i want to use double a for couple days can u help me out with this
