Are these batteries safe to use with this laser?

First of all, I am new, and I would like to say hello everyone.

The laser is this one:

I ordered with this laser these:

and this to recharge the rechargeable ones:

I need to know if these batteries would work fine with this laser, as I do not want to burn this thing up.

Also, for the sake of you guys in the US thinking of ordering this, it is safe is you used the registered airmail, my friend showed me this and I'm expecting it soon.

EDIT: OH! And I heard camera CR2s burn out the diode or shorten its life, is that true!?

Thanks guy!

just so you understand, yes it will be a burner. no you will not see the beam in the day time like the site lists. cr2 i believe is just the battery size. the ones you want are 3volts i would recommend cr2's that are 3.6 volts. it will up the power safely
