A CR 123 is 3 volt battery a LR 123A or RCR123A is 3.7 volt hence the L for lithium or R for rechargable which is 3.7 volt. You really shouldn't have a problem at all with 3.7 volt battery if its a laser. You usually only come into problems if you have two in series as instead of 6 volts you end up with 7.4 volts which could be enough to cook a diode. The CRr123 battery in basic form is 3 volt and not rechargeable(and usually tells you that on the battery) the rest are rechargeable and are 3.7 volt lithiums

Ok thx, I have found some rcr123a rechargeable 3.6 and 3.7 and like 2000 mAh where the 3.0volt I currently have in it is 1550mAh...I just wanted the opinions of some of you guys that would know what im talking about, I dont want to ruin the laser, I figured it wouldnt hurt to go up to the 3.6-3.7v but want to make sure. So I'll be good to go with the higher voltage??

Yes go for the 3.6 volt battery no problem, all my lasers use 3.6..3.7 volt rechargables so unless its weird type i cant see any problem....
