Default Battery help?

Hey, I dont know much about batteries, so i need some help.
I have a laser housing which can hold two cr123a batteries (or the lr123a batteries that im using). Unfortunately they only supply a max of 4v (8v together) and i need atleast 9v for my laser to run at 100%. Are there any other batteries that would get me to 9v while still fitting inside my housing???
thanks!

Default Re: Battery help?

The 8.4 VDC that two lithium ion cells would deliver . . .

should easily power your laser.
