Batteries : rechargeable or not ?

It's about batteries.
I've bought a cheap green laser pointer from eBay, it is said to be 240mw (but I know it's not).

It needs 2 AAA batteries, and I have some rechargeable ones.
Since rechargeables are 550 mAh, do you think can I use them instead of regular AAAs ?

Regards,
Ray.

Yep rechargeables will be fine.

Rechargeables are great for most lasers, but sorry to say that you just got scammed. That "240mW" will just put out 20-30mW.

And gallons of infra-red light.

Rechargeables are fine, though they put out less voltage than is needed to burn stuff. It's not likely you'll be burning anything with that laser anyway, though. Not unless it's leaking (and it probably is) a fuckload of IR.

Thanks for the answers.
I tested with 2 AAA batteries and 2 rechargeable ones, and got a better spot with non rechargeables.

I know about the "true" power of those pointers. I just wanted a clear beam at night and it's enough.
BTW, my daughters wouldn't appreciate to see their balloons popping

I know about IR too, I hope someone (or something) will "see" it whem I'm pointing Beta Pictoris or Aldebaran :
