I just got the 1 watt version of this laser in the mail and it says to use 16340 batteries. What I'm wondering is, does it matter if I use 3.2 volt batteries or do I need to use 3.7? I have a seemingly unlimited supply of 3.2v batteries from where I work and it would be nice if I could use those. But I don't want to ruin the laser and will get 3.7 volt batteries if I need to. Also, if I do need 3.7 batteries then don't be afraid to point me towards a reputable supplier. Thanks in advance.
