Batteries Question

I am looking at buying a laser and it says it requires (but does not come included with) 1 18650/16340 Battery.

Er... what is that? Where can I get one? When I try searching it on google it just directs me to other lasers.

These are 3.7V li-ion rechargeable batteries. You can buy them anywhere on Chinese shops or here from a forum member Larry.
